First Level
Class: ________________________________ Session:__________________________
Addition and
Subtraction
First Level (1)
I can share ideas with
others to develop ways
of estimating the
answer to a calculation
or problem, work out
the actual answer, then
check my solution by
comparing it with the
estimate
MNU 1-01a
RECALL
Number bonds to 10 e.g. 3 + 7, or
what to add to a single digit
number to make 10,
e.g. 3+
= 10 or
+ 7 = 10
I have investigated how
whole numbers are
constructed, can
understand the
importance of zero
within the system and
can use my knowledge
to explain the link
between a digit, its
place and its value.
MNU 1-02a
I can use addition,
subtraction,
multiplication and
division when solving
problems, making best
use of the mental
strategies and written
skills I have developed.

Emphasise the use of estimation and rounding in calculations
Re-order numbers when adding, e.g. put the larger number first
Count on or back in 1’s,2’s,5’s,10’s
Partition small numbers, e.g. 8 + 3 = 8 + 2 + 1,
Partition and combine tens and ones, partition and combine multiples of tens and ones
Partition: double and adjust, e.g. 5 + 6 = 5 + 5 + 1
Partition: bridge through 10 and multiples of 10 when adding and subtracting
Partition: count on in tens and ones to find the total/difference
Partition: add a multiple of 10 and adjust by 1
Partition: add or subtract 10 or 20 and adjust
Partition: count on or back in minutes and hours, bridging through 60 (analogue times)
Use patterns of last digits, e.g. 0 and 5 when counting in fives
Use knowledge of pairs making 10, e.g.60 – 7 think 10 – 7 = 3, so 60 – 7 = 53
Identify pairs totalling 10 or multiples of 10

STRATEGIES – Learners should understand when to use and be able to apply these strategies.
See Multiplication and Division mental maths booklet

Emphasise the use of estimation and rounding in calculations

Use patterns of last digits e.g. 0 and 5 when counting in fives

Partition: double the tens and ones separately, then recombine

Partition then recombine e.g. double 35 = double 30 + double 5

Using halving as inverse of doubling and doubling is equivalent to multiplying by 2

Use multiplication facts from the 2,3,4,5,9,10 times tables e.g. Recognise that there are 15 objects altogether because there are 3 groups of 5.

Link multiplication and division facts to unit fractions e.g. Finding 1/3 of 9 = 9 ÷ 3

Recognise that when multiplying by 10 or 100, the digits move one or two places to the left and zero is used as a place holder, also applying
the inverse.

Peter Patilla strategies e.g. Counting stick

Recognise that finding a unit fraction is equivalent to dividing by the denominator and use knowledge of division facts

Emphasise the importance of using mental maths skills and recall in a variety of contexts, e.g. Money
