Square Circles

Estimate the value of one of the most famous irrational numbers. The hands-on lesson instructs classmates to measure the circumference and diameters of circles using yarn. The ratio of these quantities defines pi.

In this geometry worksheet, students create a map that uses various geometrical concepts. The final project is the creation of a "geometrical town." Rubric for grading is included.

A second installment in a series on circles, this production demonstrates the process of finding the area of a circle. As an introductory tool, it is effective. However, it does not explain the reasoning behind the formula because that...

Young scholars explore measurements of a circle. In this lesson about circumference and radius, students practice calculating measurements of a circle. Young scholars estimate, calculate, and practice with graphing all while learning...

Mathematicians analyze the relationships between surface area and volume. They conduct Internet research, conduct various experiments, record the data in a spreadsheet, and graph the results and compare the rate of increase of surface...

Sixth graders use geoboards and dot paper to experiment with geometric concepts. In this geometry lesson, 6th graders complete four activities using geoboards or dot paper including naming points on a coordinate plan and finding the area...

Students explore fairness. In this fairness lesson, students recieve a envelope of materials, not all envelopes contain the same materials. Students cut shapes to specific measurements and get money for them. If the shapes are not...

Students see circles in real life and have fun with them
