The model shows a fact family for the numbers 8, 5, and 13. The equations that represent this fact family are:
8 + 5 = 13
5 + 8 = 13
13 - 5 = 8
13 - 8 = 5
Therefore, the correct response is:
8 + 5 = 13, 5 + 8 = 13, 13 − 5 = 8, 13 − 8 = 5
Which fact family does the model show?
The bar diagram has 8 counters on the left and 5 counters on the right. The whole bar diagram is labeled with the number 13.

8 + 7 = 15, 7 + 8 = 15, 15 − 7 = 8, 15 − 8 = 7
8 + 7 = 15, 7 + 8 = 15, 15 − 7 = 8, 15 − 8 = 7
8 + 6 = 14, 6 + 8 = 14, 14 − 6 = 8, 14 − 8 = 6
8 + 6 = 14, 6 + 8 = 14, 14 − 6 = 8, 14 − 8 = 6
8 + 5 = 13, 5 + 8 = 13, 13 − 5 = 8, 13 − 8 = 5
8 + 5 = 13, 5 + 8 = 13, 13 − 5 = 8, 13 − 8 = 5
8 + 4 = 12, 4 + 8 = 12, 12 − 4 = 8, 12 − 8 = 4
