Tangram Circles: Fractions, Geometry, Algebra, and a Generous Helping of Pi


Description
If your students are working with pi and calculating the areas or circumferences of circles, this activity will give them plenty of practice. Students will use πr2 to calculate the areas of circles and regions within them. Each model progresses in complexity from simple to advanced. This can be used as an individual or team activity with upper middle school and high school students in regular education or more advanced students at lower grade levels. Students can even create their own circular designs using the included template for a culminating project.
