Cambridge Primary Cambridge Primary Mathematics 0096 Progression Grid Number Counting and sequences Stage 1 Stage 2 1Nc.01 Count objects from 0 to 20, recognising conservation of number and one-to-one correspondence. 2Nc.01 Count objects from 0 to 100. Ensure learners use one-toone matching, and know that numbers are in a fixed order. Develop numbers 20 to 99 first before revisiting teen numbers (11-19) as learners find them difficult to learn because in English they do not follow the same wording convention as other numbers. e.g. = 2 = two Learners visualise, then count numbers orally before being introduced to the number symbols. Ensure learners recognise conservation of number. e.g. there are fewer objects in the first row than the second row. Stage 3 Stage 4 Stage 5 Stage 6 When counting, learners group objects in twos, fives or tens. e.g. 34 = three groups of ten and two groups of two. Cambridge Primary Mathematics 0096 Progression Grid v1.2 1 1Nc.02 Recognise the number of objects presented in familiar patterns up to 10, without counting. 2Nc.02 Recognise the number of objects presented in unfamiliar patterns up to 10, without counting. Ensure learners have instant recognition of number patterns recognition without counting (subitising). Use resources to represent a variety of groupings for the same number. Use resources such as ten frames, dice, spinners, cards and dominoes to help learners visualise without counting. using ten frames to represent the number 5 e.g. e.g. 1Nc.03 Estimate the number of objects or people (up to 20), and check by counting. 2Nc.03 Estimate the number of objects or people (up to 100). 3Nc.01 Estimate the number of objects or people (up to 1000). Ensure learners understand that estimating is more appropriate in some contexts and accurate counting in others. e.g. choose from 10, 20, 50 or 100 when the number of objects is 47 Learners provide a range when estimating large numbers, e.g. that there are between 300 and 500 when there are 420 objects. e.g. learners should be able to recognise if the amount of sweets is enough for the number of people. Learners interpret and discuss estimations made by self and others. Use examples with objects that are not easily countable (raisins in a box). Cambridge Primary Mathematics 0096 Progression Grid v1.2 As learners become more confident encourage them to refine (narrow) their range. Encourage learners to mentally group objects into tens or hundreds when estimating. 2 Ensure learners understand that estimating means getting a number that is as close as possible to the actual number. Learners interpret and discuss estimations made by self and others. Learners interpret and discuss estimations made by self and others. 1Nc.04 Count on in ones, twos or tens, and count back in ones and tens, starting from any number (from 0 to 20). 2Nc.04 Count on and count back in ones, twos, fives or tens, starting from any number (from 0 to 100). 3Nc.02 Count on and count back in steps of constant size: 1-digit numbers, tens or hundreds, starting from any number (from 0 to 1000). 4Nc.01 Count on and count back in steps of constant size: 1-digit numbers, tens, hundreds or thousands, starting from any number, and extending beyond zero to include negative numbers. 5Nc.01 Count on and count back in steps of constant size, and extend beyond zero to include negative numbers. 6Nc.01 Count on and count back in steps of constant size, including fractions and decimals, and extend beyond zero to include negative numbers. Ensure learners make the connections between counting on and addition, and counting back and subtraction. Ensure learners relate counting on from zero (and back) to the 2, 5, and 10 times tables. Ensure learners relate counting on from zero, (and back) to 2, 3, 4, 5, 6, 8, 9 and 10 times tables. e.g. count on or count back in hundreds from 344: 344, 244, 144, … Use examples that start at a positive number and go beyond zero. Use examples that require knowledge of all times tables, focusing on 7, 8 and 9 and on those that start at a positive number and go beyond zero. Use fraction and decimal examples that include tenths, hundredths and thousandths and fraction examples that use small denominators. e.g. count back from 5 in threes: 5, 2, -1, … e.g. count back from 15 in sevens: 15, 8, 1, -6, … from 0.7; starting from , e.g. find 1 less than 19, count back 1, find 10 less than 19 count back 10. Ensure learners can also count on (and back) not only starting from zero. e.g. count on in tens from seven: 7, 17, 27, 37, … or count on in 100s from 159: 259, 359, 459, … Cambridge Primary Mathematics 0096 Progression Grid v1.2 e.g. count back in tenths 1 3 1 count on in steps of ; 3 starting from 0.4, count back in steps of 0.2. Ordering and comparing decimals are covered in the sub-strand Fractions, decimals and percentages when equivalence is introduced. 3 1Nc.05 Understand even and odd numbers as ‘every other number’ when counting (from 0 to 20). 2Nc.05 Recognise the characteristics of even and odd numbers (from 0 to 100). 3Nc.03 Use knowledge of even and odd numbers up to 10 to recognise and sort numbers. 4Nc.02 Recognise and explain generalisations when adding and subtracting combinations of even and odd numbers. Use the ten frame to show the pattern of odd and even numbers. Even numbers show pairs, odd numbers show pairs with one extra. e.g. Even numbers have the digit 0, 2, 4, 6 or 8 in the ones place. Odd numbers have the digit 1, 3, 5, 7 or 9 in the ones place. e.g. 589 is odd because it has the digit 9 in the ones place. even + even = even and Ensure learners know that if the total number of objects belongs to the 2 times table (can be counted in twos) then it is an even number. Learners recognise that an even number of objects can be shared into 2 equal groups and odd numbers cannot. Ensure learners understand that if numbers can be divided by 2 then the number is even, if they cannot then the number is odd. Ensure learners understand that when counting on from an even number (including zero), every alternate number is even, when counting on from an odd number every alternate number is odd. even – even = even, odd + odd = even and odd – odd = even, odd + even = odd and odd – even = odd, Start by using examples with numbers between 0 and 10 so learners can recognise the generalisations e.g. 3 + 3 = 6 so odd + odd = even 3 + 2 = 5 so odd + even = odd Use examples that learners will understand the underlying structure 5 + 5 = 10 4 + 1 + 4 + 1 = 10 4 +1 + 4 +1 = 10 4 + 4 + 2 = 10 The two left over (1 and 1) make an even number. 3Nc.04 Recognise the use of an object to represent an unknown quantity in addition and subtraction calculations. Cambridge Primary Mathematics 0096 Progression Grid v1.2 4Nc.03 Recognise the use of objects, shapes or symbols to represent unknown quantities in addition and subtraction calculations. 5Nc.02 Recognise the use of objects, shapes or symbols to represent two unknown quantities in addition and subtraction calculations. 6Nc.02 Recognise the use of letters to represent quantities that vary in addition and subtraction calculations. 4 Any object can represent an unknown. An unknown has a fixed value. Use objects familiar to learners. An object, shape or symbol can represent an unknown. Start with easy recognisable shapes. e.g. e.g. a farmer has two pieces of wood that are different lengths (metres) and the sum of the lengths is 45 metres. What lengths are the pieces of wood? Give all possible lengths. Learners are shown a picture of two identical bars of chocolate with a price tag of $2 for both price of chocolate + price of chocolate = $2 + + = $2 1m 44m = $3 1m + + = 12 kg What is the value of one ? Total e.g. A more difficult example might be: 45m ++++=1.3kg 45m Learners are shown a picture of a bar of chocolate and a football with a price tag of $10 for both. + = $10 Learners recognise that the unknowns are the price of Cambridge Primary Mathematics 0096 Progression Grid v1.2 + What are the possible values of and ? 44m - represents a mass in kg = 45 Allow learners to use their own strategies then suggest strategies for checking that they have found all possible answers. Variables can be different values. e.g. e.g. Four identical cans have a mass of 12 kg, what is the mass of 1 can? metres Learners are shown a $10 note and how much they have left after buying a football. The unknown represents the price of a football. $10 Use examples with numbers that are easy to calculate as this objective is about understanding pre-algebra and not complex calculations. e.g. + = $25 A B Learners are presented with two cups, one labelled A and the other labelled B. They are given 10 counters. Learners are asked to find all of the different ways that they can place the counters into the cups. This problem can be represented algebraically by writing A + B = 10. A and B vary because they can have lots of different values. For example, if A = 0, then B =10; if A = 1, then B = 9; if A = 2, then B = 8 and so A + B = 10. Link to other strands such as Geometry and Measure. e.g. s Learners are shown two pictures, one picture of two identical bars of chocolate with a price tag of $25 for both and another picture of a football and piece of chocolate with a price tag of $21 for both. The perimeter (p) of a square with side length (s) could be represented as p = s + s + s+ s. The value of s would be different for different size squares. 5 the chocolate and the price of the football and can represent the objects as shapes. e.g. Learners recognise that the unknowns are the price of the chocolate and the price of the football. + = 10 where the square represents the price of the chocolate bar and the circle represents the price of the football. Learners are shown a $10 note and how much they have left after buying a football. The unknown represents the price of a football. $10 - = $3 Learners recognise that the unknown is the price of the football and can represent the object as a shape. e.g. 10 - = + $21 price of chocolate + price of chocolate = $25 price of football + price of chocolate = $21 or + = 25 + = 21 Learners should be able to find the solution that each chocolate bar costs $12.50 and the football costs $8.50. $10 - = - $1 =3 The circle represents the price of the football. $10 - = $8 Learners should be able to find the solution that the chocolate costs $2 and therefore the ball costs $7 or 10 - = 8 10 - Cambridge Primary Mathematics 0096 Progression Grid v1.2 -=1 6 1Nc.06 Use familiar language to describe sequences of objects. 2Nc.06 Recognise, describe and extend numerical sequences (from 0 to 100). 3Nc.05 Recognise and extend linear sequences, and describe the term-toterm rule. 4Nc.04 Recognise and extend linear and nonlinear sequences, and describe the term-to-term rule. 5Nc.03 Use the relationship between repeated addition of a constant and multiplication to find any term of a linear sequence. 6Nc.03 Use the relationship between repeated addition of a constant and multiplication to find and use a position-to-term rule. Look at these shapes and describe what you see. Ensure the focus is on identifying patterns of numbers. Term-to-term rules describe how a term is produced from the term or terms before it and is also known as recursion rule. Term-to-term rules describe how a term is produced from the term or terms before it and is also known as recursion rule. Use examples where sequences are formed by adding and subtracting a constant. e.g. the sequence of odd numbers 1, 3, 5, 7, 9, 11, … has the recursion rule: 'the next term is 2 more than the previous term'. Therefore, 13 (11 + 2), 15 (13 + 2), and 17 (15 + 2) are the next three terms. Use examples of addition, subtraction, multiplication and division, with or without using a number line, extending beyond zero to include negative numbers. Ensure learners recognise that the pattern: 4, 8, 12, 16 are the answers to the four times table, and so the 10th term in the sequence can be found with 4 x 10 = 40. e.g. they are all squares, and the colour is blue, green, red, blue, green, red so the next one is blue. Patterns may be based on colour, shape or size of objects including symmetrical patterns in the environment (link to geometry and measure). e.g. when counting in ones or twos from 21 to 29, learners recognise the pattern: the tens digit stays the same and the ones digit changes. Examples should use numbers that are easily accessible to learners (2, 5 or 10 times tables) as this learning objective focusses on recognition of patterns rather than complex calculations. e.g. the sequence 5, 10, 20, 40 … has the recursion rule: 'the next term is two times the previous term’. 1, 2, 4, 8, 16 …. (doubling); 1000, 200, 40, 8, 1.6 …. (÷5) Use examples where the rule is given. e.g. if the rule is ‘add 2 and multiply by 3’, the next number in the sequence 1, 9 would be 33. Cambridge Primary Mathematics 0096 Progression Grid v1.2 e.g. the following sequence has steps of constant sizes 11, __, __, 23. Therefore, to find the missing numbers, learners need to identify that from 11 to 23 is 12 (three jumps of four). Ensure learners understand the difference between a term and position as this will assist them when they are formally introduced to algebra in the Lower Secondary curriculum. Use tables or mapping diagrams to assist learners in seeing connections between the terms, pattern and position. Position 1 2 3 4 5 6 10 ? 20 100 Term 3 6 9 12 15 ? ? 45 ? ? 7 3Nc.06 Extend spatial patterns formed from adding and subtracting a constant. 4Nc.05 Recognise and extend the spatial pattern of square numbers. e.g. continue the pattern by adding 3 triangles 3 + 3 + 3 is nine triangles Cambridge Primary Mathematics 0096 Progression Grid v1.2 6Nc.04 Use knowledge of square numbers to generate terms in a sequence, given its position. Use visual examples to assist learners to see the pattern. e.g. diagrams are provided. Learners extend the pattern to the 10th term. is 3 triangles 3 + 3 is six triangles 5Nc.04 Recognise and extend the spatial pattern of square and triangular numbers. The diagram shows that the first term is 1 (1x1), the second term is 4 (2x2), so the next term will be 9 (3x3). 1 1 dot 2 3 dots 3 6 dots 4 10 dots e.g. a diagram with the first term 1 (12) and second term 4 (22) is given. Learners recognise that the fifth term will be 52 = 25, and the tenth term will be 102 = 100. 8 Number Money Stage 1 Stage 2 Stage 3 1Nm.01 Recognise money used in local currency. 2Nm.01 Recognise value and money notation used in local currency. 3Nm.01 Interpret money notation for currencies that use a decimal point. This includes: This includes recognising the currency symbol for your country (e.g. $, £, €, ₹) e.g. the notation $1.50 means 1 dollar and 50 cents or 3 dollars and 25 cents is the same as $3.25 Differentiating the size and colour of notes and coins (if appropriate). Playing with fake money (without focusing on value and notation). Stage 4 Stage 5 Stage 6 Ensure learners understand to the left of the decimal point is dollars and to the right of the decimal point is cents. So the decimal point is a separator for dollars and cents. Although some countries do not use decimal notation or coins, Cambridge International adopts dollar notation as an internationally recognised currency. 2Nm.02 Compare values of different combinations of coins or notes. 3Nm.02 Add and subtract amounts of money to give change. e.g. 1 dollar is the same as two 50 cents coins: In local currency and also in the dollar currency: The concept of money is completed in Stage 3. From Stage 4 onwards, learners continue to use money in context, e.g. creating and solving problems, using decimal notation, discounted prices, converting between currencies, recognising when two quantities are directly proportional. Learners are not introduced to decimal places until Stage 5. 1, 5, 10, 25, 50 cents 1, 2, 5, 10, 20, 50 and 100 dollars e.g. to pay $3.55 you could use three 1 dollar notes, 50 cents and 5 cents or three 1 Cambridge Primary Mathematics 0096 Progression Grid v1.2 9 From Stage 2, Cambridge International adopts dollar notation as the standard notation for money as it is an internationally recognised currency. dollar notes, five 10 cents and 5 cents. Or if you used four 1 dollar notes, you would receive 45 cents change. Even though decimal places are not introduced until Stage 5, you can still ask learners questions related to money e.g. Sara has $10. She buys a pen for 4 dollars and 60 cents and a pencil for 3 dollars and 30 cents. How much change will she be given? 2 dollars and 30 cents. Cambridge Primary Mathematics 0096 Progression Grid v1.2 10 Number Integers and powers Stage 1 Stage 2 Stage 3 Stage 4 1Ni.01 Recite, read and write number names and whole numbers (from 0 to 20). 2Ni.01 Recite, read and write number names and whole numbers (from 0 to 100). 3Ni.01 Recite, read and write number names and whole numbers (from 0 to 1000). 4Ni.01 Read and write number names and whole numbers greater than 1000 and less than 0. e.g. Number name is ‘one’ and is represented by the symbol ‘1’ Ensure learners understand the relationship between number names and numbers, and only include place value if this has already been covered (see sub-strand Place value, ordering and rounding). Ensure learners understand the relationship between number names and numbers, and only include place value if this has already been covered (see sub-strand Place value, ordering and rounding). Ensure learners understand that 6542 is read as 6 thousands, 5 hundreds and forty-two but 86 542 is read as 86 thousands and not 8 ten thousands. This links to place value. e.g. number name is ‘twenty’, and is represented by the symbols ‘20’ using two numerals (digits) ‘2’ and ‘0’ and is the same as 2 tens and 0 ones (place value). e.g. number name is ‘three hundred and forty-one’, and is represented by the symbols ‘341’ and is the same as 3 hundreds, 4 tens and 1 one (place value). Ensure learners understand that number words and numbers are in a fixed order. One-to-one correspondence is covered in the sub-strand Counting and sequences Stage 5 Stage 6 For negative numbers, initially only use examples that use number lines, scales (e.g. thermometer). or other resources to assist calculations. Show position of positive and negative numbers around zero recognising that negative numbers are to the left of zero on a number line. Ensure learners understand that in English the number -34 is read as “negative thirty four” and not “minus thirty four”. Cambridge Primary Mathematics 0096 Progression Grid v1.2 11 1Ni.02 Understand addition as: - counting on - combining two sets. Introduce these concepts of addition using concrete apparatus, then pictorial representations before using the abstract notation of the + symbol. Start with numbers to 10, ensuring that examples do not use numbers greater than 20. 2Ni.02 Understand and explain the relationship between addition and subtraction. 3Ni.02 Understand the commutative and associative properties of addition, and use these to simplify calculations. Initially use materials (counters, dominos or dice) and symbols that show small numbers. Ensure learners understand that these properties do not apply to subtraction because e.g. 1 + 2 = 3 and 2 + 1 = 3, so 3 - 1 = 2 and 3 – 2 = 1 5 – 3 = 2 whereas 3 – 5 2 (negative numbers are covered in Stage 4). Then use examples that total 10 to reinforce complements of ten (number pairs) and the relationship between addition and subtraction. Ensure learners understand that when numbers are added their order can be changed without affecting the total. e.g. if 6 + 4 = 10, and 4 + 6 = 10, then 10 – 6 = 4, 10 – 4 = 6. e.g. Ensure learners understand that addition and subtraction are inverses. Do not use any examples where the total is greater than 100. 2 + 3 = 5 is the same as 3+2=5 3 + 4 + 6 = 13 is the same as 6 + 4 + 3 = 13 or 4 + 6 + 3 At this stage, learners have not been introduced to brackets so introduce associative property of addition informally e.g. If 2 + 3 + 5 = 10 then 2+3+5= 2 + 3 + 5 = 5 + 5 = 10 or ⏟ 5 2+⏟ 3 + 5 = 2 + 8 = 10 8 Cambridge Primary Mathematics 0096 Progression Grid v1.2 12 1Ni.03 Understand subtraction as: - counting back - take away - difference. Introduce these concepts of subtraction using concrete apparatus, then pictorial representations before using abstract notation of the symbol. Ensure learners know “difference” in the form of ‘How many more or how many less?’ 1Ni.04 Recognise complements of 10. 2Ni.03 Recognise complements of 20 and complements of multiples of 10 (up to 100). 3Ni.03 Recognise complements of 100 and complements of multiples of 10 or 100 (up to 1000). Complements to 10 is the same as number bonds, or number pairs that total 10. It is important to include 0 and 10. Ensure learners are secure with numbers to 20 before introducing numbers to 100. Ensure learners are using their knowledge of the addition number facts to 10 and 20 and the related subtraction facts. 10 + 0 = 10, 0 + 10 = 10, 9 + 1 = 10, 1 + 9 = 10 etc. Numbers that total less than 10 are covered later in this sub-strand e.g. 6 + 1 = 7, 8 – 2 = 6 e.g. Use addition and subtraction examples 15 + 5 = 20, 20 – 5 = 15, 12 + 8 = 20, 20 – 8 = 12, 20 – 12 = 8). For complements of 100, initially use numbers that end in 0 or 5. Complements of multiples of 10 (up to 100) e.g. 70 + 30 = 100 or 85 + 15 = 100 e.g. 20 + 60 = 80, 70 - 30 = 40 and then 76 + 24 = 100 or 13 + 87 = 100 Numbers that total less than 100 (that do not require Cambridge Primary Mathematics 0096 Progression Grid v1.2 13 regrouping) are covered later in this sub-strand e.g. 0 + 15 = 15 , 15 – 0 = 15, 41 + 36 = 77, 82 – 31 = 51 Complements of multiples of 10 (up to 1000) refer to multiples of 10 within 1000 e.g. 430 + 280 = 710, 640 - 270 = 370. Complements of multiples of 100 (up to 1000) refer to multiples of 100 within 1000, e.g. 400 + 300 = 700, 800 - 200 = 600. Start with multiples of 100 first, e.g. 400 + 300 = 700, 800 - 200 = 600, and then multiples of 10, e.g. 430 + 280 = 710, 640 - 270 = 370. 1Ni.05 Estimate, add and subtract whole numbers (where the answer is from 0 to 20). 2Ni.04 Estimate, add and subtract whole numbers with up to two digits (no regrouping of ones or tens). 3Ni.04 Estimate, add and subtract whole numbers with up to three digits (regrouping of ones or tens). 4Ni.02 Estimate, add and subtract whole numbers with up to three digits. 5Ni.01 Estimate, add and subtract integers, including where one integer is negative. 6Ni.01 Estimate, add and subtract integers. Ensure learners can estimate simple calculations so that they recognise when an answer is incorrect without a formal calculation. For addition calculations, the total should not exceed 100. For addition calculations, the total cannot exceed 1000. Use examples that require regrouping of ones and tens. Also use examples such as: Do not use examples that require regrouping of ones or bridging through ten. For subtraction calculations, initially do not use numbers with zeros. e.g. 207 – 29 = e.g. 358 + 45, 328 – 49, Use examples that find the difference between positive and negative integers, and between two negative integers. e.g. 1 + 5 = 6 cannot equal 17 e.g. 35 + 8 and 45 – 6 Use addition and subtractions examples such as: Add a pair of numbers by putting the larger number first and counting on. Use the + sign and know that = sign represents equivalence. Use examples such as: Add four or five small numbers 1 + 2 + 2 + 3 Add and subtract numbers that do not require regrouping e.g. 12 + 7 = 19 Cambridge Primary Mathematics 0096 Progression Grid v1.2 Pairs of 2-digit numbers 14 + 27 or 27 – 19 3-digit with 1-digit numbers 243 + 8 or 243 – 8 3-digit numbers with 2-digit numbers or 134 + 345 + 412 Ensure learners can estimate simple calculations so that they recognise when an answer is incorrect without a formal calculation. For large numbers learners can check using a calculator. Pairs of 3-digit numbers 243 + 171 + 359 Integers with more than 3digits 243 + 23 + 3478 For addition use examples that add a positive integer to a negative integer. For negative integers only, start with small numbers and include examples that use number lines or scales to support calculations. e.g. 30 – 5 = 25, - 30 – 5 = 35, - 30 + 5 = -25, 30 + 5 = 35 Learners start to understand addition and subtraction of integers using number line and familiar contexts such as rise and fall of temperature. e.g. -5 + 405 = 400. 14 17 – 5 = 12. Ensure learners know that number facts on either side of the = sign have the same value. 35 + 4, 30 + 9 45 – 3, 29 – 9, 12 + 12, 25 – 20, 17-15, 55 41. Present the calculations in different formats. e.g. 36 + 23 and 36 23 + e.g. 6 + 5 = 10 + 1 For subtraction, the minuend (number from which you are subtracting) must be 20 or less. 243 + 28 or 243 – 28, 243 + 71 or 243 – 71 3-digit numbers with multiples of 10 or 100 243 + 90 or 243 – 90 243 + 200 or 243 – 200 Pairs of 3-digit numbers 243 + 128 or 243 – 128 243 + 171 or 243 – 171 For both addition and subtraction calculations, do NOT use examples that require regrouping before introducing examples that do require regrouping. e.g. 235 + 23 = 258 and 174 – 139 = 35 then examples that require regrouping of ones and tens 325 + 449 = 774 For subtraction, use examples that subtract a positive number from any integer where the result is negative and use a number line to support learners if required e.g. 30 – 35 = -5 Ensure learners can estimate simple calculations so that they recognise when an answer is incorrect without a formal calculation. For large numbers learners can check using a calculator. e.g. if the temperature falls from 2 degrees to -4 degrees, learners count six steps (from right to left) on a number line to conclude that it is a fall of 6 degrees. Ensure learners can estimate simple calculations so that they recognise when an answer is incorrect without a formal calculation. For large numbers learners can check using a calculator. Ensure learners can estimate simple calculations so that they recognise when an answer is incorrect without a formal calculation.

So, 3 is in the ten thousand position and represents 30 000. If the digit to the right of the 3 is 4 or less (representing 34 000) then round the 3 down to 30 000. If the digit to the right of the 3 is 5 or more (representing 35 000) then round the 3 up to 40 000. So in this example the number would round down to 1 230 000. e.g. 2.4, 2.3, 2.2, and 2.1 round down to 2, whereas 2.5, 2.6, 2.7, 2.8 and 2.9 round up to 3.

Ensure learners can interpret fractions as comparing a part of a set of objects (partwhole discrete). Ensure learners can interpret fractions as comparing a part of a set of objects (partwhole discrete). Include activities that include half of sets of objects (discrete whole) Ensure learners understand that parts of a set can be put back together to make a whole set. Ensure learners can interpret fractions as comparing a part of a set of objects (partwhole discrete). A fraction is always a fraction of something and learners need to be able to describe the whole (the ‘something’) as well as the parts. Learners should be able to find half of any even number of objects between 0 and 20, e.g. half of 8 is 4. e.g. this is one-quarter of a set of balls. How many balls are in the set? e.g. 1 4 of the marbles are blue, so 3 4 of the marbles are white. Cambridge Primary Mathematics 0096 Progression Grid v1.2 32 You have some marbles and you pick up 3 marbles and that is one third. How many marbles do you have? 2Nf.03 Understand that one half and one quarter can be interpreted as division. 3Nf.04 Understand that a fraction can be represented as a division of the numerator by the denominator (half, quarter and three-quarters). 4Nf.02 Understand that a fraction can be represented as a division of the numerator by the denominator (unit fractions and threequarters). 5Nf.01 Understand that a fraction can be represented as a division of the numerator by the denominator (unit fractions, three-quarters, tenths and hundredths). 6Nf.01 Understand that a fraction can be represented as a division of the numerator by the denominator (proper and improper fractions).

Do not include examples that result in a mixed or improper fraction. e.g. half of 6 = 3 quarter of 12 = 3 Cambridge Primary Mathematics 0096 Progression Grid v1.2 Fraction as operator: a unit fraction is understood to be a number that acts on another number in the sense of shrinking the magnitude of the number. e.g. Find 1 10 of 100. The answer is 10. The operator, 1 10 , decreases the original value from 100 to 10. 3 2 of 6 is equal to 9. Ensure learners understand that operators are multiplicative rather than additive. 10 1 5Nf.02 Understand that proper fractions can act as operators. 3 10 of 100m is 30m Ensure learners understand that to solve this example several combinations of operations could occur: - Divide100m by 10 then multiply by 3 or Multiply 100m by 3 then divide by 10 The answer 30m is less than 100m because 100m was multiplied by a fraction less than 1 Ensure learners understand that they can multiply a quantity that represents a fraction to find the whole quantity e.g. If 1 4 of a length is 36cm, then the whole length is 36 × 4 = 144cm. 35 2Nf.05 Recognise the 1 1 3 4 2 4 relative size of , , and 1, and the equivalence of 1 2 2 2 4 4 2 4 and , and , and 1.

When learners have mastered equivalent fractions introduce them to the equivalence of fractions, decimals (place value) and percentage, initially using ½ and 1 only, then progressing to tenths and hundredths (one decimal place only). Include equivalences of fractions, decimals and percentages for hundredths (one or two decimal places). e.g. 100 50 100 100 100 10 100 40 100 is 50% = 1 2 = 0.5 is 100% = 1 = 1 10 = 4 10 e.g. 60 100 25 100 72 6 = 10 = 1 4 = 3 5 = 60% = 0.6 = 25% = 0.25 = 72% = 0.72 Use examples with mixed numbers 1 e.g. 1 = 1.25 4 = 10% = 0.1 = 40% = 0.4 1Nf.04 Understand and visualise that halves can be combined to make wholes. 2Nf.06 Understand and visualise that wholes, halves and quarters can be combined to create new fractions. 3Nf.07 Estimate, add and subtract fractions with the same denominator (within one whole). 4Nf.05 Estimate, add and subtract fractions with the same denominator. 5Nf.05 Estimate, add and subtract fractions with the same denominator and denominators that are multiples of each other. 6Nf.05 Estimate, add and subtract fractions with different denominators. In examples start by using the words one half and only At this stage do not use the fraction notation for three In examples use fraction notation. Use examples that add and subtract proper fractions with proper fractions (same denominator). Learners use diagrams to add and subtract fractions. Use examples that add and subtract proper fractions with proper fractions (same denominators and denominators that are multiples of each other).

When discussing proportion use the language “in every” or “out of”. When discussing ratio use the language “for every” e.g. imagine a row with a repeating pattern of 3 white squares and 1 grey square. Etc. Proportion: 1 in every 4 squares is grey Ratio: For every 1 grey square there are 3 white squares Ensure learners understand that the order of the numbers is important in a ratio. e.g. in a bag there are 4 red and 5 blue counters. The ratio of red to blue is 4:5 not 5:4 Ensure learners understand how to write proportion and ratio (including using the notation ‘:’) for a given situation and write proportion in different ways using knowledge of equivalence of Cambridge Primary Mathematics 0096 Progression Grid v1.2 6Nf.12 Understand the relationship between two quantities when they are in direct proportion. Ensure learners understand what is meant by “in proportion”. e.g. a model is in proportion to a real dog. The dog is 9 times as big as the model. If the model is 4cm tall, the real dog will be 36cm tall (9 x 4 = 36). If the real dog’s tail is 18cm long, the tail on the model will be 2cm long (9 x 2 = 18)? Ensure learners understand that when one quantity increases (or decreases) the other quantities increase (or decrease) in the same ratio. E.g. A photocopy is in proportion to the original. If the original is 30cm by 40cm. What sizes can be the photocopies? Use simple recipe examples e.g. to adapt a recipe for 6 people to one for 3 or 12 people 43 fractions and percentages (multiples of 10). e.g. in a bag there are 4 red, 3 green counters and 3 blue counters. The ratio of red to green to blue counters is 4:3:3. The proportion of red is 4 10 which is also the same as 40%. 6Nf.13 Use knowledge of equivalence to understand and use equivalent ratios. e.g. the following ratios are equivalent e.g. a builder uses sand and cement. He uses 3 bags of sand for every 2 bags of cement. If there are 10 bags of cement, how many bags are sand? Use a table or diagram to assist learners. Sand Cambridge Primary Mathematics 0096 Progression Grid v1.2 3 15 Cement 2 10 44 When discussing ratio, ensure learners understand that a ratio shows the relationship between two or more quantities, so a single number cannot express a ratio.

Daily routines (bedtime stories; yesterday, today, tomorrow; morning, afternoon and evening). Learners should understand relationships such as: a second is less than a minute, an hour is more than a minute, etc. e.g. age is measured in years, we sleep for approximately 8 hours, a football match lasts 90 minutes. Relationships such as Match the activity to its likely time span: blink of an eye, boil an egg, run 25m, walk 100m. Learners need to know that there are 60 minutes in an hour to read a clock. They do not need to know that there are 60 seconds in a minute or 24 hours in a day. Introduce activities that allow learners to estimate how many times they can do an activity in one minute, one hour, etc. Recognise the everyday language used to describe familiar activities related to time e.g. your birthday happens once a year, we play the same sport every day or every week. Learners do not need to understand the relationship between units of time. Learners should be able to order the days of the week and the months of the year by name with or without the aid of a calendar e.g. Wednesday comes before Thursday. 60 seconds(s) in a minute (min) 60 minutes in an hour (h) 24 hours in a day number of days in each month (including leap years) 52 weeks in a year 12 months in a year Stage 6 Likely time span: 0.5sec, 5min, 5sec, 25sec Use whole numbers only (e.g. 100 minutes is one hour and 40 minutes). In Stage 5 learners are introduced to decimals in the Number strand when adding and subtracting numbers. However, do not use examples involving time in decimals such as 1.5 hours as learners often misinterpret this as 1 hour and 50 minutes instead of 1 hour and 30 minutes. 1Gt.02 Know the days of the week and the months of the year. Cambridge Primary Mathematics 0096 Progression Grid v1.2 46 1Gt.03 Recognise time to the hour and half hour. 2Gt.02 Read and record time to five minutes in digital notation (12-hour) and on analogue clocks. 3Gt.02 Read and record time accurately in digital notation (12-hour) and on analogue clocks. 4Gt.02 Read and record time accurately in digital notation (12- and 24-hour) and on analogue clocks. 5Gt.02 Compare times between time zones in digital notation (12- and 24-hour) and on analogue clocks. e.g. ten o’clock in the morning, half past three in the afternoon. e.g. twenty-five past one in the afternoon (1:25), twenty to ten in the morning (9:40), quarter past in the evening (10:15), half past three in the afternoon (3:30), quarter to nine (8:45) in the evening. e.g. sixteen minutes past one in the afternoon (1:16), 9:40 can be read as 40 minutes past 9, twenty to ten in the morning or twenty to ten in the evening. e.g. 3:30 in the afternoon can be recorded as 15:30 or 3:30pm, and 3:30 in the morning as 3:30 or 3:30am. e.g. a quarter to four in the afternoon is later than 15:40. Ensure learners understand that when 24 hours is reached, they have reached a new day and must go back to zero with their counting. Ensure learners understand that the world is divided into 24 time zones but the comparison between time zones will depend on the time of year. Learners continue to read, record and compare times in context (12- and 24-hour clocks). Ensure learners understand that clocks are usually set one hour apart in adjacent time zones. Some countries have more than one time zone. 2Gt.03 Interpret and use the information in calendars. 3Gt.03 Interpret and use the information in timetables (12-hour clock). 4Gt.03 Interpret and use the information in timetables (12- and 24hour clock). Ensure learners understand that calendars are used to organise time in days, weeks and months of a particular year. Ensure learners understand that timetables are a plan of times at which events are scheduled to take place usually organised in hours and minutes. Ensure learners understand that timetables often use a 24-hour clock to differentiate between morning, afternoon and evening times. Learners continue to interpret and use calendars and timetables to calculate times (12- and 24-hour clocks). 3Gt.04 Understand the difference between a time and a time interval. Find time intervals between the same units in days, weeks, months and years. 4Gt.04 Find time intervals between different units: 5Gt.03 Find time intervals in seconds, minutes and hours that bridge through 60. Cambridge Primary Mathematics 0096 Progression Grid v1.2 - days, weeks, months and years 47 - seconds, minutes and hours that do not bridge through 60. Ensure learners understand that the difference between being 5 years old and the interval 5 years: a time interval measures the length of time between two given times. e.g. A journey that starts at 7:00 on February 15th and ends at 7:30 on February 16th has a time interval of 1 day and 30 minutes. Ensure learners can bridge through 60 e.g. a digital clock that displays 5:57 in five minutes will display 6:02 not 5:62 e.g. If an project runs from February to June, it represents a time interval of 4 months. An activity happening in February, happens 2 months earlier than an activity in April. Use examples that use the same units only, so that learners do not need to convert between units. 5Gt.04 Recognise that a time interval can be expressed as a decimal, or in mixed units. 6Gt.01 Convert between time intervals expressed as a decimal and in mixed units. e.g. know that 0.5 hours corresponds to 30 minutes or 0.5 minutes corresponds to 30 seconds or 1.5 days is equivalent to 1 day and 12 hours not 1 day and 5 hours, so that learners can calculate time intervals represented in a decimal format. Start with examples that are easy recognisable and easy to calculate e.g. 5.5 hours is equivalent to 5 hours and 30 minutes. 3.25 hours is equivalent to 3 hours and 15 minutes (0.25 1 1 is 4 and 4 of an hour is 15 minutes) Learners should understand that time can be represented Cambridge Primary Mathematics 0096 Progression Grid v1.2 48 in decimal format (usually as the result of a calculation) and that it can be converted to hours and minutes, and even parts of a minute. e.g. 1.5 hours is equivalent to 1 hour and 30 minutes not 1 hour and 50 minutes Tenths can be converted easily 0.1 min 0.2 min 0.3 min 6s 12 s 18 s 0.1 h 0.2 h 0.3 h 6 min 12 min 18 min e.g. convert 3.7 hours into hours and minutes 0.7 x 60 = 42 minutes 3 hours and 42 minutes Do not include examples where learners need to convert from whole numbers to decimals. e.g. 11 seconds into minutes Cambridge Primary Mathematics 0096 Progression Grid v1.2 49 Geometry and Measure Geometrical reasoning, shapes and measurements Stage 1 Stage 2 Stage 3 Stage 4 Stage 5 Stage 6 1Gg.01 Identify, describe and sort 2D shapes by their characteristics or properties, including reference to number of sides and whether the sides are curved or straight. 2Gg.01 Identify, describe, sort, name and sketch 2D shapes by their properties, including reference to regular polygons, number of sides and vertices.

Introduce learners to regular polygons only. e.g. pentagons, hexagons and octagons Identify and recognise that squares, circles, triangles and rectangles are 2D shapes. Learners continue to use shapes to make patterns using physical equipment including repeating a shape to see if it will fit together (tessellation). Familiarise learners with regular and irregular polygons. e.g. combine two triangles to make a larger triangle or square Include: e.g. combine two parallelograms to make a larger parallelogram. Further parallelograms can be added to form a tessellating pattern. Semi-circles and circles relevant information (properties) irrelevant information (e.g. characteristics such as colour) non-examples (e.g. dice). shapes in a range of different orientations reference to number of sides, number of vertices, curved, straight edges. Ensure that learners identify and sketch examples of 2D shapes in patterns, art and architecture e.g. Learners should be able to identify non-examples, relevant and irrelevant information.

What is the perimeter and area of this shape? e.g. if the area of this rectangle is 8cm2 Include lines that can be measured in cm or m. Know the meaning of ‘kilo’, ‘centi’ and ‘milli’ Ensure learners discover for themselves that the area of a square or rectangle can be found by multiplying one side length by the other side length. 1 m = 100 cm 1 km = 1000 m For area use the terminology ‘square units’ rather than cm2, m2 e.g. The area of the square below is 16 square units Cambridge Primary Mathematics 0096 Progression Grid v1.2 e.g. a rectangle has a perimeter of 32 cm, what is the area of the rectangle? Why? Ensure learners use the notation for area, square centimetres (cm2) and square metres (m2). - perimeter using millimetre (mm), centimetre (cm), metre (m) and kilometre (km) and understand their relationships - area using square centimetres (cm2) and square metres (m2) and square kilometres (km2). 4cm 2cm (Perimeter 30cm, Area 29cm2) Then, the area of each right angle triangle is 4cm2 2cm 4cm 53 4Gg.04 Estimate the area of irregular shapes on a square grid (whole and part squares).

They are not expected to use the terminology ‘curved surface’. e.g. Circles on a cylinder, triangle on a pyramid. e.g. compare the similarities and differences between pyramids and prisms e.g. compare the similarities and differences between squares, rectangles, cubes and cuboids. Use isometric paper or other resources to assist in sketching 3D shapes. Sketch rather than accurately draw. e.g. find the least number of centimetre cubes needed to turn this shape into a cuboid: Emphasise the properties of shapes rather than just their names. Ensure learners use and combine 3D shapes to make patterns and other familiar 3D shapes, e.g. the 3D shapes Learners continue to use shapes to make patterns.

Estimate and measure the capacity of familiar objects using nonstandard or standard units. 3Gg.07 Estimate and measure capacity in millilitres (ml) and litres (l), and understand their relationships. Use liquids only. 1 litre = 1000 ml Cambridge Primary Mathematics 0096 Progression Grid v1.2 Learners continue to use mass in context. 6Gg.05 Understand the difference between capacity and volume. Learners continue to use capacity in context. Volume is the amount of space taken up by an object, while capacity is the measure of an object's ability to hold a substance, like a solid, a liquid or a gas. 55 e.g. a flask can have a capacity of 1 litre but be filled with 0.5 litre of water. So, the volume of water is 0.5 litre. 1Gg.06 Differentiate between 2D and 3D shapes. 2Gg.08 Identify 2D and 3D shapes in familiar objects. 3Gg.08 Recognise pictures, drawings and diagrams of 3D shapes. 4Gg.06 Match nets to their corresponding 3D shapes. 5Gg.05 Identify and sketch different nets for a cube. 6Gg.06 Identify and sketch different nets for cubes, cuboids, prisms and pyramids.

Describe rotational symmetry as ‘order 𝑥’. e.g. Using a mirror or folding to confirm. Using a mirror or folding to confirm. e.g. a sheet of paper folded in half (line of symmetry); a sheet of paper folded unevenly (no line of symmetry). Ensure that learners understand that the same shape or pattern can have more than one line of symmetry. e.g. all lines of symmetry of squares, rectangles, pentagons, octagons, parallelograms e.g. colour three more squares so that this pattern has 2 lines of symmetry e.g. an equilateral triangle has rotational symmetry order 3, a square has rotational symmetry order 4; the letters A and T do not have rotational symmetry but they do have lines of symmetry Learners can use turn and rotate interchangeably This includes identifying examples in the environment. e.g. a picture of a butterfly showing the mirror line or fold line and looks identical only once in a full turn.

Identify right angles in 2D shapes and in the environment. Ensure learners recognise that a right angle is a quarter turn. Learners identify whether angles are greater than or less than a right angle. Do not measure angles, instead use benchmarks 90 degrees, 180 degrees to identify less than or more than 90 or 180 degrees. Know that a reflex angle is greater than 180º but less than 360º. Use full circle protractors to draw or measure angles. No need to draw or measure angles. 123º 247º Ensure learners know that: an angle less than a right angle is called an acute angle an angle greater than a right angle and less than a straight line is called an obtuse angle a quarter turn is 90 degrees a half turn is 180 degrees a three-quarter turn is 270 degrees a full turn is 360 degrees Cambridge Primary Mathematics 0096 Progression Grid v1.2 e.g.36º.

Ordinal points represent angles less than 90º. Emphasise oral descriptions rather than reading and writing them. Learners start creating and interpreting simple grid maps. e.g. Imagine you are facing south. Write the instructions for the route from start to finish. Start with: Move south 1 square, turn right …… Stage 5 Stage 6 e.g. describe all the different routes from A to B, travelling only northeast or northwest Start N Use simple scales, legends and directions to interpret information contained on a map.

First quadrant only. Ensure learners understand that coordinates can be represented by both negative and positive values, and fractions and decimals. Identify points on a 2D grid using coordinates (the first number represents the movement in the horizontal direction and the second number the vertical direction). Start to use the language: the first number refers to the x coordinate and the second number refers to the y coordinate, referring to x-axis and y-axis. e.g. Point (2,6) is further away from y-axis than point (1,3). This is point (5, 5). Estimate the position of (1,3).

Ensure learners can describe and perform a translation on a square grid using up, down, left, right or a combination of horizontal and vertical movements in the first quadrant Ensure learners can describe and perform a translation on a first quadrant and all four quadrant coordinate grid using up, down, left, right. e.g. A square ABCD has been translated 3 squares to the right. e.g. Translate the blue square 7 squares up. Learners are not expected to identify points using coordinates. They should use their geometrical knowledge. Coordinates are a separate concept that is Cambridge Primary Mathematics 0096 Progression Grid v1.2 65 covered in another learning objective. Ensure that learners understand translation as movement along a straight line whilst maintaining its size, shape and orientation (every vertex moves in the same direction by the same amount). Reflection and rotation of shapes should be on squared paper only at this stage, whereas translation can be done using coordinates. Learners should join the corresponding corners of a pair of translated shapes together to show the lines formed are parallel and the same length (in comparison to reflection where the lines are parallel but not equal length). 2Gp.02 Sketch the reflection of a 2D shape in a vertical mirror line, including where the mirror line is the edge of the shape. 3Gp.02 Sketch the reflection of a 2D shape in a horizontal or vertical mirror line, including where the mirror line is the edge of the shape. 4Gp.03 Reflect 2D shapes in a horizontal or vertical mirror line, including where the mirror line is the edge of the shape, on square grids.

Learners should sketch the shapes on plain paper rather than on grids because it is the concept of reflection that is important rather than accuracy. Ensure learners visualise and sketch the result of reflecting a shape along one edge to create new shapes. This includes examples in the environment.

Ask questions such as: Learners do not need to know formal definitions such as “categorical and discrete data”. Learners do not need to know formal definitions such as “categorical and discrete data”. Learners do not need to know formal definitions such as “categorical, discrete and continuous data”. Learners do not need to know formal definitions such as “categorical, discrete and continuous data”. Discrete data refers to data that can be counted and has a finite number of possible values in a given range, such as number of siblings, how many books they have read this month etc. Include examples where learners need to decide what data to collect in order to answer the question Continuous data refers to data that can be measured and has an infinite number of possible values within a selected range, e.g. mass, height, temperature. Ensure learners make predictions before conducting their investigation. Ask questions (on topics familiar and of interest to learners). e.g. What is your favourite fruit? Questions can be cross curricular, e.g. if reading The Very Hungry Caterpillar: Which food did the caterpillar eat the most? What is your favourite book? (non-statistical) What is the favourite genre of book of people in this class? (statistical) Discuss the difference between a statistical and non-statistical question with learners so they are familiar with these terms. A non-statistical question is one with a deterministic answer (it has a single answer), whereas a statistical question is one that will have variable answers so collecting data is necessary for it to be answered. Ask questions such as: How many 3-letter words are on this page? (nonstatistical) What length are the words in children’s books? (statistical) e.g. Which of these two children’s books is easier to read? For this question learners could suggest a number of different measures to investigate such as: word length number of pictures number of pages words per page. Include examples where learners need to decide what data to collect in order to answer the question. Learners should investigate a range of these ideas, rather than just one. e.g. Do 10-year olds have larger body measurements than 9year olds? For this question learners could suggest a number of e.g. “I think my data will show that 10-year olds have a larger shoulder width and shoe size than 9-year olds” Ask questions that allow learners to collect more than two variables including categorical per observation, to allow comparison of subgroups. e.g. data collected for height and gender could be split into male heights and female heights and compared e.g. Cambridge Primary Mathematics 0096 Progression Grid v1.2 68 different measures to investigate such as: height hand span leg length arm span shoulder width shoe size Learners may decide to investigate height, shoulder width and shoe size to answer the original question. Is there a connection between a person’s height and their other body measurements? Learners may decide to investigate whether there is a link between height and hand span, or height and shoe size. This relationship is best analysed using scatter graphs.

Record using a tally chart and include a column to present frequencies Continue to use tally charts and frequency tables where appropriate and explain choice of data representation. Include frequency tables with percentages to cover the idea of frequency as a proportion of the whole population Representing grouped discrete data in a frequency table e.g. e.g. Eva Record discrete data, e.g. Representing continuous data in a frequency table (not using ≤, < until later stages) Pierre Carlos Learners organise information into lists or tables: Apple Banana Eva Pierre They should explain the advantages and disadvantages of using a list, table or tally chart, to organise information.

Carlos Venn and Carroll Use Venn or Carroll diagrams to sort numbers or objects using one criterion; explain choices using appropriate language including ‘not’. e.g. Students can select their own groupings for discrete or continuous data Use Venn or Carroll diagrams to sort numbers or objects using one criterion or two criteria; explain choices using appropriate language including ‘not’. e.g. sorting shapes by colour (red and not red, circles and not circles). Cambridge Primary Mathematics 0096 Progression Grid v1.2 Continue to use Venn and Carroll diagrams with one or two criterion where appropriate and explain choice of data representation. For Venn diagrams, introduce the universal set and entries outside the chosen sets. Use Venn diagrams or Carroll diagrams to sort data and objects using up to three criteria. e.g. use a Venn diagram to compare characteristics of animals. Continue to use Venn and Carroll diagrams where appropriate and explain choice of data representation. Continue to use Venn and Carroll diagrams where appropriate and explain choice of data representation. For 2 sets learners can create Carroll diagrams from Venn diagrams and vice versa. 70 Block graph, pictogram, bar chart Use pictograms first and then show how this data can be represented in block graphs where one object or drawing represents one data value Draw block graphs directly from information presented in tally charts e.g. Use pictogram where one object or drawing represents one or two data values. e.g. each image represents two cars e.g. Introduce the terminology of axes and initially use examples that use words Cambridge Primary Mathematics 0096 Progression Grid v1.2 Use examples that record data in bar charts (discrete data), and do not use histograms (frequency diagrams for continuous data) as this requires knowledge of continuous data. Ensure learners know the difference between bar charts (discrete data) and frequency diagrams, or histograms, (continuous data) and can explain which representation to use in a given situation. Use bar chart scales in 1s, 2s, 5s, 10s and 20s. Use bar chart scales in 1s, 2s, 5s, 10s, 20s and 100s. Introduce bar charts with grouped discrete data represented in groups of 2 (1 – 2, 3 – 4 etc.), 5 (1 – 5, 6 – 10 etc.) and 10 (1 – 10, 11 – 20 etc.) e.g. Ensure learners understand the impact of representations where scales have different intervals, e.g. comparing 71 rather than numbers on x axis. Ensure learners understand that a bar chart of discrete data includes a gap between each bar, e.g. They should explain the advantages and disadvantages of using a pictogram or block graph to represent information. Ask learners to choose suitable equal class intervals where appropriate. and At this stage do not use examples that require histograms (frequency diagrams for continuous data) as this requires knowledge of continuous data. Use bar chart scales in 1s and 2s. Dot plots Use dot plots to record data, where each dot represents 1 count. Use dot plots to record data, where each dot represents one data point rather than one dot per count. e.g. Cambridge Primary Mathematics 0096 Progression Grid v1.2 Number of pets 0 1 2 3 Frequency 6 2 3 5 Continue to use dot plots where appropriate and explain choice of data representation. e.g. Number of pets 0 1 2 3 Frequency 6 2 3 5 72 Waffle diagrams and pie charts Use diagrams that represent proportions in data, e.g. waffle diagrams, to assist learners in understanding percentage and proportions of the whole sample or population. e.g. waffle diagrams: or Cambridge Primary Mathematics 0096 Progression Grid v1.2 Use examples where the total frequency is 4, 5, 10 or 20. If using other frequencies, ensure learners are provided with a pre-divided pie chart using dots around the edge of a circle. For example, for a total frequency of 12: Record data in waffle diagrams with 100 squares and related pie charts to assist learners in understanding the proportion of a population. e.g. 73 waffle diagram: pie chart: Frequency diagrams Cambridge Primary Mathematics 0096 Progression Grid v1.2 Ensure learners know the difference between bar charts (discrete data) and frequency diagrams, or histograms, (continuous data). Continue to use frequency diagrams for continuous data (histograms) where appropriate and explain choice of data representation. Provide learners with the scales and a partially complete diagram. Ensure learners can complete and add data to frequency diagrams for continuous data (histograms) with equal class intervals. Use scales for frequency such as 1s, 2s, 5s and 10s. 74 Use simple scales for frequency such as 1s. Line graphs Use line graphs to represent continuous data, e.g. temperature over time Continue to use line graphs where appropriate and explain choice of data representation. Use examples that require learners to read between grid lines. Use examples that include grid lines Scatter graphs Cambridge Primary Mathematics 0096 Progression Grid v1.2 Use examples that record data in scatter graphs to draw a line of best fit as learners will use these in science. 75 Use simple scales, for example 1s or 2s. Stage 1 Stage 2 Cambridge Primary Mathematics 0096 Progression Grid v1.2 Stage 3 Stage 4 Stage 5 Stage 6 5Ss.03 Understand that the mode and median are ways to describe and summarise data sets. Find and interpret the mode and the median, and consider their appropriateness for the context. 6Ss.03 Understand that the mode, median, mean and range are ways to describe and summarise data sets. Find and interpret the mode (including bimodal data), median, mean and range, and consider their appropriateness for the context. 76 e.g. Ana’s last five marks out of 10 were 1, 1, 5, 6, 7 Median: 5 Mode: 1 Ensure learners understand that in this situation the mode is not an appropriate measure as most of Ana’s marks (3 out of 5) were above 5. In this case, therefore, they should choose the median. The mode represents the marks that occurred the most and the median is the value that leaves the same number of data above and below it (2 marks below 5 and 2 marks above 5). Introduce median of an odd number of events so that the median is a whole number. First review median of odd number of events and then introduce median of even numbers. e.g. Becky’s last six marks out of 10 were 1, 1, 5, 7, 8, 8 Median: (5 + 7) = 12 = 6 2 2 Mode: 1 and 8 Mean = 5 In the example above, learners should recognise that there are three marks below the median and three marks above the median 1, 1, 5 below 6 7, 7, 8 above 6 If a shop manager wants to find out which size people buy on average, they should look into the mode as this represents the size they sell the most. If a company wants to report on the average salaries of their employees, they should use median as it will not be affected by the very high and very low salaries. If a student has had 1, 1, 1, 1, 2 and 3 as the last six Cambridge Primary Mathematics 0096 Progression Grid v1.2 77 marks, the mean would be more representative as it would be above 1 and would show that the student got some marks above 1. 1Ss.03 Describe data, using familiar language including reference to more, less, most or least to answer non-statistical questions and discuss conclusions. 2Ss.03 Describe data, identifying similarities and variations to answer nonstatistical and statistical questions and discuss conclusions. 3Ss.03 Interpret data, identifying similarities and variations, within data sets, to answer nonstatistical and statistical questions and discuss conclusions. 4Ss.03 Interpret data, identifying similarities and variations, within and between data sets, to answer statistical questions. Discuss conclusions, considering the sources of variation. 5Ss.04 Interpret data, identifying patterns, within and between data sets, to answer statistical questions. Discuss conclusions, considering the sources of variation. 6Ss.04 Interpret data, identifying patterns, within and between data sets, to answer statistical questions. Discuss conclusions, considering the sources of variation, and check predictions. Questions should be on topics that are familiar and of interest to learners. Within data refers to data collected about the preferred book genre of all learners in a class: Within data refers to data collected about word length of all words on one page of one children’s book: Between data refers to data collected about word length of all words on one page of two children’s books: Learners identify patterns within and between the data sets. Learners check whether their predictions were correct or incorrect and give possible reasons for this. The Very Hungry Caterpillar example: Use the diagrams to compare quantities, order items from most eaten to least eaten etc., and explain reasoning. Genre Number Adventure 12 Fact book 5 e.g. “The food that the caterpillar ate the most of was oranges. He ate more plums than apples. Maybe the caterpillar likes plums more than apples.” Scary stories 9 Word length 1 2 3 4 5 6 Number 10 11 13 9 7 2 Children’s book A Word length 1 2 3 4 5 6 Number 10 11 13 9 7 2 Children’s book B Word length 1 2 3 4 5 6 7 Number 6 6 9 8 7 4 2 Book A Cambridge Primary Mathematics 0096 Progression Grid v1.2 Book B Book A Book B e.g. “Both bar charts show the same bump. They go up and then down again. This is because they both have the most 3-letter words. The mode word length for both books is 3 letters.” e.g. “We thought there would be the most 1-letter and 2letter words in children’s books. Actually there were more 3-letter words. This might be because the words ‘and’ and ‘the’ are both 3letter words that come up a lot.” Use examples that cover the idea of frequency as a proportion of the whole population. e.g. “The bars are more similar heights in the bar chart for book B than book A. The bump isn’t as steep.” 78 Ensure learners interpret the data in context (presented in tables, bar charts, pictograms etc.) e.g. Learners should not say “the shortest bar is 6-letter words” instead they should say “The bar chart shows that there were fewest 6letter words. There were only two 6-letter words on the page” They should identify similarities and variations within the data set. e.g. “There were two more 4letter words than 5-letter words” Learners describe the data presented in tables, block graphs, pictograms etc. e.g. “The highest column on the block graph is adventure” “The most popular genre was adventure books” “The second column is shorter than the first column” Cambridge Primary Mathematics 0096 Progression Grid v1.2 Learners notice similarities and variations within data sets. e.g. “There were the same number of 1-letter and 2letter words in book B” They also make comparisons between data in tables, pictograms, bar charts, dot plots etc. “Book B had less words on the page than book A, but they were a bit longer. This might be because it was a fact book, not a story book” “About 50% of words on the page have length 2-letters, 3-letters or 4-letters” e.g. “The bar charts show both books had the most 3letter words” “Book B had two 7-letter words, but book A didn’t have any 7-letter words” Learners consider the sources of variation. They explain why the data shows variations and give reasons for the differences in the data they collected for each book. e.g. “The data I collected for book A and book B is different. This might be because Book A is a story book, but book B is a fact book. Also the fact book contains more pictures on the page. The fact book includes longer words, it is more complicated to understand” 79 Statistics and Probability Probability Stage 1 Stage 2 Stage 3 Stage 4 Stage 5 Stage 6 2Sp.01 Use familiar language associated with patterns and randomness, including regular pattern and random pattern. 3Sp.01 Use familiar language associated with chance to describe events, including ‘it will happen’, ‘it will not happen’, ‘it might happen’. 4Sp.01 Use language associated with chance to describe familiar events, including reference to maybe, likely, certain, impossible. 5Sp.01 Use the language associated with likelihood to describe and compare likelihood and risk of familiar events, including those with equally likely outcomes. 6Sp.01 Use the language associated with probability and proportion to describe and compare possible outcomes. e.g. When observing Classify and make judgements on familiar events and explain why. e.g. discuss statements using the vocabulary: no chance, poor chance, even chance, good chance and certain: Compare two or more events using vocabulary: most likely, less likely, equally likely (even chance), impossible, certain. Learners are not expected to calculate probabilities. They should be using the language only. I will watch television tonight It will get dark tonight I will see a penguin on my way home from school. Learners position events on a likelihood scale, e.g. RGBRGTRGBRGSR GT learners are able to make comments like “every third letter is an R” or ”G always comes after an R”. This also includes identifying when there appears to be no pattern. Cambridge Primary Mathematics 0096 Progression Grid v1.2 e.g. using fractions: 1 out of 4 chance; using percentages: 25% chance 5Sp.02 Recognise that some outcomes are equally likely to happen and some outcomes are more (or less) likely to happen, when doing practical activities. 6Sp.02 Identify when two events can happen at the same time and when they cannot, and know that the latter are called 'mutually exclusive'. e.g. from a pack of 52 playing cards: Ensure learners understand the term ‘mutually exclusive’, e.g. turning left and turning right are mutually exclusive 80 you are equally likely to choose a red card or a black card you are more likely to choose a number card than a picture card you are less likely to choose a king or queen than an even numbered card. (you can't do both at the same time); whereas turning left and scratching your head can happen at the same time. Ensure learners recognise that some probabilities cannot be calculated by using equally likely outcomes but can be modelled through experiments involving a large number of trials. 6Sp.03 Recognise that some probabilities can only be modelled through experiments using a large number of trials. Use probability examples that require a large number of trials, e.g. roll a pair of sixsided dice and observe the sum of the numbers on the uppermost face: which total(s) occur the most often/ least often? 2Sp.02 Conduct chance experiments with two outcomes, and present and describe the results. Cambridge Primary Mathematics 0096 Progression Grid v1.2 3Sp.02 Conduct chance experiments, and present and describe the results. 4Sp.02 Conduct chance experiments, using small and large numbers of trials, and present and describe the results using 5Sp.03 Conduct chance experiments or simulations, using small and large numbers of trials, and present and describe the results using 6Sp.04 Conduct chance experiments or simulations, using small and large numbers of trials. Predict, analyse and describe the frequency of outcomes 81 Use resources that only have two outcomes such as, coins (head or tails), selecting two items from a jar, spinners with two colours. Use resources that have more than two outcomes such as a pack of 52 playing cards, a spinner with ten colours. Learners realise that if there are more equally likely outcomes they are less likely to happen. e.g. winning a game of heads/tails or choosing the ace of diamonds from a pack of playing cards. Which is more likely? Why? the language of probability. the language of probability. using the language of probability. If possible, use digital resources such as chance generators that model realworld situations, e.g. model flipping a coin by using a random number generator on a computer, or assigning even and odd numbers on a dice. Use examples that include different coloured beads in a bag so that learners cannot see how many of each colour are in the bag, so that they need to predict the results. Understand that randomness has uncertain individual outcomes but exhibit regular patterns of outcomes over many repetitions. Also include examples with spinners and coins to encourage learners to use the language of probability to describe the outcomes of experiments and games with random generators. Ensure learners understand that experimental probability is random (has uncertain individual outcomes but exhibit regular patterns of outcomes over many repetitions) and unpredictable (the next outcome is not predictable). This will help to avoid the misconception that the theoretical probability value is precise (e.g. I will get a 3 on a dice every 6 rolls). Investigate through discussion and experimentation two outcomes that are equally likely, outcomes that are more or less likely.
