Finding Thirds with Unit Squares
- Jack D. Gittinger
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 When you have found 12 ways to cover a third, print the GeoGebra screen. Find a partner who is also finished and compare your solutions. Do you agree with each other? Did you find different solutions? Are there others? How many?
