Number bonds to 10,

2
+ 7 = = = = = = = = 10 Making 10, 20 and 100 Adding can be a lot easier if we remember numbers that add to 10. Complete these number sentences to make = = = = = = = = 10

3
10 – 7 = 3 10 – 6 = 4 10 – 9 = 1 10 – 8 = 2 10 – 1 = 9 10 – 3 = 7 10 – 5 = 5 10 – 2 = 8 Making 10, 20 and 100 Subtraction can also be a lot easier if we remember pairs of numbers add to 10. Complete these number sentences. 10 – 7 = 3 10 – 6 = 4 10 – 9 = 1 10 – 8 = 2 10 – 1 = 9 10 – 3 = 7 10 – 5 = 5 10 – 2 = 8

4
= – 80 = – 70 = = = 100 Making 10, 20 and 100 If you know pairs of numbers that make 10 then you will easily work out pairs of numbers that make – 60 = – 90 = = = = = = – 70 = – 60 = – 90 = – 80 = 20 Hint: just add 0 on the end.

5
= = = = = = = = 20 Making 10, 20 and 100 We can use the numbers that make ten to help us work out the numbers that add to 20. Complete these number sentences to make = = = = = = = = 20
