Bennie has 9 apples in his ten-frame basket.
Riley brings 4 more.
"Let me fill the ten first," says Bennie.
Look at 9 + 4.
9 needs 1 more to make 10.
Break 4 into 1 and 3.
9 + 1 = 10. Then 10 + 3 = 13.
So 9 + 4 = 13.
The first frame is full. 3 more makes 13.
Ten and some more is easy.
10 + 3 = 13. 10 + 5 = 15.
The ones tell the last number.
