Explain how the fact that you chose can help.

Doubles fact: 5 + 5 = 10

Since the doubles 5 + 5 = 10, the sum of 5 + 6 will be one more. 5 + 6 = 11

Part II




Number Sentence: The sum of the numbers 8, 3, and 9 is equal to 20.

9. Look at the number sentences below.

The correct number sentences are highlighted in yellow:

16 > 20     10 < 5     3 < 7      12 > 10      8 > 8

On the lines below, rewrite the incorrect comparisons using the correct symbol. Then, explain how you know your answer is correct.

16 < 20      10 > 5      3 < 7      12 > 10       8 = 8


16 < 20 means that the number 16 is less than the number 20

10 > 5 means that the number 10 is greater than the number 5

8 = 8 means that the number 8 is equal to 8
