1 From the NCETM ‘ACTIVITIES’ Section of the New Curriculum Year 1 Fractions Activities Activities Programme of Study statements A B recognise, find and name a half as one of two equal parts of an object, shape or quantity recognise, find and name a quarter as one of four equal parts of an object, shape or quantity Activity A - NRICH Making longer, making shorter http://nrich.maths.org/5590 This activity includes doubling, halves and quarters in a very practical way using rods made from interlocking cubes. It gives children a practical context in which to explore simple multiplying and dividing, even if these particular terms are not used explicitly. It can provide a very useful context for introducing and using the vocabulary of halves and quarters. Having multilink cubes for each child is essential. Activity B – NRICH Happy Halving This problem consolidates children's understanding of halving and will help them to develop their skills of visualisation.It is important pupils are clear that, in this problem, the halves must be exactly the same size as each other. A precursor to this activity might be to show the group a square and ask them to split it in half in their "mind's eye". By discussing where they have imagined the "cutting line", the children will discover that there is more than one way to do this. From this point, you can talk about whether or not the two halves are the same size each time.It may be useful for the pupils to have a sheet of the shapes. Alternatively, they could use a pegboard or geoboard to try out their ideas . 2 Year 2 Activities Activities Knowledge and understanding covered in Year 2 Fractions Programme of Study A B C D Recognise fractions of shapes Write fractions Recognise fractions of a quantity Recognise equivalence of 2⁄4 and 1⁄2 Find fractions of objects Activity A(i) – Halving http://nrich.maths.org/1788/note This problem is a wonderful way to consolidate children's understanding of halving and halves. It also gives learners experience of mathematical proof. Activity A (ii) - Early Fraction Development http://nrich.maths.org/9746 In this article, Bernard Bagnall outlines suggestions for tasks which will help young children develop the concept of fractions Activities B – Colouring halves and quarters of shapes E.G. Colour a half of these shapes 3 Year 2 continued Colour a quarter of each shape Activities C – What fractions is shaded?

Powerpoint slides – Key Stage 1 Resources (attached) 6 Year 3 Activities Activity Programme of Study statement A B C D E F G count up and down in tenths; recognise that tenths arise from dividing an object into 10 equal parts and in dividing one-digit numbers or quantities by 10 recognise, find and write fractions of a discrete set of objects: unit fractions and non-unit fractions with small denominators recognise and use fractions as numbers: unit fractions and non-unit fractions with small denominators recognise and show, using diagrams, equivalent fractions with small denominators add and subtract fractions with the same denominator within one whole (e.g. 5/7 + 1/7 = 6/7) compare and order unit fractions, and fractions with the same denominators solve problems that involve all of the above Activity A – visualising fractions along a line Use counting sticks and bead strings to help children visualise fractions. If the bead string represents one whole, then each set of ten coloured beads could represent one tenth and each individual bead could represent one hundredth. 7 1. Label the two ends of the bead string as 0 and 1. Give students tags to place each tenth on the bead string. You could use a 1-10 bead string instead of a 1-100 bead string. 2. Join several bead strings together to create fraction lines that extend over one. For example, five bead strings allow fractional numbers from 0 to 5. Label simultaneously in mixed numbers (2 ½) and improper fractions (5/2). 3. Ask the pupils to represent each tenth with a variety of manipulatives, for example, Numicon, Dienes (Big Base) and coins. 4. Extend pupils’ understanding to include the equivalence of fractions, decimals and percentages. For example, ½ = 0.5 = 50% or 2 2/10 = 2.2 = 220% Activity B Fractional Triangles http://nrich.maths.org/2124/note This problem could be used as part of a lesson on finding fractions of various shapes. It should help develop an understanding of the relationship between the part and the whole. It allows children to explore fractions in a non-threatening, open-ended way and yet it does contain some real challenge. This practical activity develops an understanding of the part and the whole, Understanding unit fractions: A Hungarian Approach (pdf downloaded) A series of lessons on finding fractions of amounts from Lesson 11, page 9 onwards based on an alternative, Hungarian approach, to teaching maths. There are linked resources and activities, although the site is slightly tricky to navigate. Activity C Trains (downloaded as a word document) An activity from New Zealand that involves using number rods to develop children’s understanding that fractions can extend beyond 1.

A range of difficulty levels makes this game easy to adapt. http://www.funbrain.com/fractop/index.html Activity E(i) : Folding ribbons Show the children a lengths of ribbon (or string) measuring 3/4 metre in length. Fold it into three parts. What fraction of the ribbon have we found? ( 1/3 ). Measure the folded piece together. How long is it? ( 1/4 m). So, 1/3 of 3/4 or 1/3 x 3/4 = 1/4. Try this with other fractions and starting lengths. Activity E(ii) – ratio tables Ask children to use their multiplication tables to scale recipe quantities up and down to complete the table below. Consider their multiplication of simple fractions for quantities of vanilla extract and chocolate chips. Ingredients 3 cupcakes 6 cupcakes 12 cupcakes Self- raising flour 130 gm Caster Sugar 100 gm Butter 125 gm Large Eggs 2 Vanilla extract ½ teaspoonful Chocolate chips ¾ cupful 18 cupcakes 24 cupcakes 260 gm 1 teaspoonful 19 Activity F(i) - Pizzas This pizza themed fraction resource from the TES can be used in many different ways, and includes several suggestions from the author. http://www.tes.co.uk/teaching-resource/Fractions-Pizzas-6142902/ Activity F(ii) – Planetary Wars Published by BEAM, and hosted within the National STEM Centre E-library, this two-player dice game requires children to find fractional quantities of numbers. http://www.nationalstemcentre.org.uk/elibrary/maths/resource/3364/fraction-games-for-students-aged-9-11 Activity G – Decimal Point Chair When multiplying or dividing by powers of ten, the key issue to emphasise in many classrooms is that it is not the decimal point which moves, but the digits of the number. Prepare a range of cards to include several zeros, a decimal point and two whole numbers [e.g. 2 and 7]. Give a group of children one card each and ask the child with the decimal point to sit in the middle of a row of chairs, facing the class. Ask the 2 children with the cards with whole numbers to choose a chair to sit on, leaving no empty chairs between them and the decimal point. Explore ways to do this. Then introduce one zero in various places and talk about the numbers created. Add a second zero and do the same. Move on to asking the children to decide what happens to the number created if we multiply or divide by 10, then 100, then 1000 – emphasise that the decimal point must not move. Ask children to consider ways in which they might record this.
