This middle school and high school resource contains three great geometry activities in one coupled with Common Core alignment and research tips. Answer keys are included.
- Knowing the Angles: Versions 1 & 2 — Students will construct polygons and find their interior angles. They will discover patterns that help them make predictions about other polygons. Multiple options allow for both younger and older students to participate and to understand the concepts. They will begin by using tangrams and then graduate to more sophisticated applications as they generalize their discoveries.
- Clock Angles — Students will model given times on a clock face and find the interior and exterior angles formed by the hands. They will use protractors and ratios to measure the angles and work with proportional reasoning.
- Geoboard Squares — Students will explore the different ways to build squares on a geoboard in this engaging and intriguing exploration.They can use the Pythagorean Theorem to prove which squares can be built on the grid and which squares cannot.
