Subtraction Jumping Strategy

When we break down 24 - 12 using the JUMP strategy, it might look like:

• 24 - 10 - 2

• 24 - 12 - 10

Which sum do these JUMPS show?

• 93 - 32 = 61

• 93 - 61 = 32

• 32 + 61 = 92

Which sum do these JUMPS show?

• 77 - 51 = 26

• 77 - 26 = 51

• 51 + 26 = 77

When we break down 57 -24 using the JUMP strategy, it might look like:

• 57 - 10 - 10 - 4 = 33

• 57 - 20 - 5 = 33

• 57 - 10 - 10 - 1 - 1 - 1 = 33

DRAW the JUMP strategy for 30 - 14 =

Answer explanation

Good work!

Answer explanation

30 - 17 = 13

Well done!

Using the JUMP strategy, the sum 118 - 23 might look like.......

• 118 - 10 - 10 - 3 = 95

• 118 - 10 - 13 = 95

• 118 - 23 = 95

This JUMP strategy shows which SUM?

• 100 - 28 = 72

• 100 - 48 = 52

• 100 - 38 = 62

• 100 - 58 = 42

Use the jump strategy to subtract 123 - 116 =

• 7

• 9

• 11

• 3

Use the jump strategy to subtract 341 - 257 =

• 95

• 84

• 72

• 63
