To decompose 17 using ten frames, you can start with 10 in the first frame and 7 in the second frame.
Then, to compose 10 and 17, you can add the total number of dots in both frames, which is 10 + 7 = 17.
Therefore, the equation 10 + 17 = 17 can be represented using ten frames.
Compose and decompose numbers 11-20 using ten frames. 10 + 17 =
