The other equation she can use is
6 + 3 = 9
I changed the addends to show the other equation she can use.

Question 6.
Mike adds 6 + 4 + 3. Show two ways he might solve the problem. Circle the addends you add first.
6 + 4 + 3 =
___ + ___ = ___
So, 6 + 4 + 3 = ___

Explanation:
First add  4 and 3
4 + 3 = 7
Then add 6 and 7
6 + 7 = 13
So, 6 + 4 + 3 = 13.

6 + 4 + 3 =
___ + ___ = ___
So, 6 + 4 + 3 = ___

Explanation:
First add 6 and 4
6 + 4 = 10
Then add 10 and 3
10 + 3 = 13
So, 6+ 4 + 3 = 13

Question 7.
Carl sees 2 birds in a nest. He sees 1 bird on the ground. He sees 3 birds in the sky. How many birds does Carl see?
