Written methods in Year 2

Addition Draw a picture, tally, dots Number lines to count in 1’s and bridging through 10. Empty Number lines. Counting on in 10’s and 1’s. Counting on in multiples of 10 and 1’s. Counting in 10’s and bridging through the next 10. Compensating (e.g. 24 + 19; add 20, subtract 1)

Have a go... 34 + 23 = 43+19= 16 + 28 = 11+17=

Subtraction Draw a picture, tally, dots Number lines to count back in 1’s and bridging through 10. Empty Number lines. Counting back in 10’s and 1’s. Counting back in multiples of 10 and 1’s. Counting back in 10’s and bridging through 10. Counting on (finding the difference).

Have a go... 23 - 11 = 41 – 19 = 35 – 29 = 27 – 15 =

Multiplication Draw a picture Repeated addition Arrays eg. 4 x 3 = 3 x 4 Number lines, counting on in equal steps. (Knowing the times tables , x2, x5, x10)

Have a go... 7 x 5 = 3 x 5 = 6 x 10 = 9 x 2 =

Division Secure knowledge of multiplication facts. Sharing Grouping (repeated subtraction) Grouping on a number line.

Have a go... 12 / 2 = 20 / 5 = 16 / 2 = 18 / 3 =
