This step can sometimes seem a little anti-climatic for teachers. Big question: does our answer fall within our range?

Routine: Connecting Representations

a) 10 + 1 = 11 b) 5 + 6 = 11 c) 6 + 6 – 1 = 11 d) 5 + 5 + 1 = 11

a) 10 + 5 = 15 b) 7 + 7 + 1 = 15 c) 8 + 8 - 1 = 15 d) 8 + 7 = 11

1 a) 7 + 1 b) 4 + 4 2 c) 10 - 2 3 d) 6 + 2 4 e) 5 + 3
