Question

Write or draw to explain two ways you can find the sum of 3+4+5

Answer 1

1+1+1+1+1+1+1+1+1+1+1+1 is one way and
3+9 or
7+5

Answer 2

3+4+5.

You could split it into different groups because of the communative property.

These are two combonations. :) (I'll put 3 so you can chose)

3 + 4 = 7 + 5 = 12.

3 + 7 = 10 + 4 = 14

7 + 4 = 11 + 3 = 14
