Question

When adding 46+17, Laura realizes that 6 and 7 give her a 2digit number. Can you guide Laura to solve her problem?

A. Compose a ten and solve the problem.
B. Explain the place value strategies.

Answer 1

46 = 40 + 6
17 = 10 + 7

First add 40 and 10 together

40 + 10 = 50

Than add the remaining, 6 & 7 together

6 + 7 = 13

Add 50 & 13 together (as it is much easier to)
50 + 13 = 63

63 is the answer


i'm not sure what the place value strategy is so i think you'll have to do it


hope this helps though
