Make a ten

Fill the ten frame first. Then add or take away the rest.

1.
Circle every fact that makes 10.

4 + 57 + 36 + 32 + 89 + 15 + 48 + 14 + 6

2.

There are 9 orange fish in the tank. Then 4 blue fish swim in. Break 4 into 1 and 3 to make a ten.

9 + 1 =  
10 + 3 =  
So 9 + 4 =   fish

3.

Kofi sees 8 starfish. Then he sees 6 more. Break 6 into 2 and 4 to make a ten.
