Creating Equations from Arrays

A sheet for practicing writing equations based on an array given .

Cover a Rectangle

Using colored tiles, choose a three rectangles to cover with those tiles. Explain how many tiles where used to partition each rectangle into rows and columns. Write an equation.

Roll a Rectangle Array
