Finding Thirds with Unit Squares
Instructions
The Challenge
Use the POINTER tool to move unit squares to cover exactly one third of the area of each of the green rectangles. Find 12 different ways to do this. Remember, you are not trying to divide the rectangle into three thirds. You are trying to cover one-third the area of the rectangle.
Print and Discuss
