Use Area Models to Divide 6 to 9 Groups by Grouping 3-98

Divide by grouping up to 9 in each group. What's 42÷6? If a rectangle has 42 unit squares and 6 in each row, how many rows? 5x6 = 30, so 7x6 = 42. Scaffold from known facts to learn new facts. Area of a rectangle? 42. Length of one side? 6. Length of the other side? 7. Given the area and one side, find the other side.
