Joel's solution
To solve , Joel places base 10 blocks representing 3.7 on the mat below.
Then he separates them into groups of 0.2.
He found 18 groups of 0.2 with 0.1 left over. Joel says the answer is 18.1.
Is Joel correct? How do you know? How can you use the base 10 blocks to explain the quotient? Use a number line to model the same problem and strategy.
