Did Alex put the correct pieces together? Activities
1. Draw lines to match the boxes with the same value.
I think they are equivalent !
16 + 5 38 – 30 24 – 7 22

13 + 4 12 + 9 2 + 2 + 4 32 – 10

2. Tick (4) the correct number sentences.

17 – 4 = 26 – 8 4 + 8 + 3 = 18 – 3

15 + 4 = 23 – 4 25 + 4 = 17 + 12

16 – 4 = 27 – 12 30 – 15 = 7 + 7

Look!
