In the hop, skip and jump (Triple Jump) the record for men is 18.29m whereas the record for women is 15.5m. How much longer is the men’s record than the women’s.
Answer: 2.79
Strategy: 15.5 + .59 = 16.09
16.09 + 2 = 18.09
18.09 + .2 = 18.29
2 + .59 + .2 = 2.79
There are 8 boxes. Each box has 25 apples in it. How many apples are there altogether?
Answer: 200
Strategy:
8 x 25:

8 x 10 = 80
80 x 2 = 160
5 x 8 = 40
80 x 2 = 160 … 160 + 40 = 200
