Finding Fourths with Unit Squares
- Jack D. Gittinger
The Challenge Use the POINTER tool to move unit squares to cover exactly one fourth of each of the orange rectangles. Find 12 different ways to do this. Remember, you are not trying to divide the rectangle into four fourths. You are trying to cover one-fourth the area of the rectangle. Print and Discuss When you have found 12 ways to cover a fourth, 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 other solutions? How many?
