Addition 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?

• 12 + 10 = 22

• 12 + 15 = 27

• 12 + 5 = 17

Which sum do these JUMPS show?

• 23 + 21 = 50

• 23 + 21 = 44

• 33 + 11 = 44

When we break down 57 + 56 using the JUMP strategy, it might look like:

• 57 + 10 + 10 + 10 + 10 + 10 + 6 = 113

• 57 + 10 + 6 = 113

• 57 + 10 + 10 + 10 + 6 = 113

DRAW the JUMP strategy for 15 + 12

DRAW the JUMP strategy for 13 + 17

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

• 118 + 10 + 10 + 3 = 141

• 118 + 10 + 13 = 141

• 118 + 30 = 141

This JUMP strategy shows which SUM?

• 43 + 16 = 59

• 69 - 20 = 43

• 53 + 10 = 63

• 43 + 26 = 69
