Polygons and Plane Figures
Students choose a polygon to define and describe, and use Power Point and the Internet to present their polygon.
Curated OER
Geo-Mat
Young scholars review plane figures by playing a game that resembles "Twister." They listen to directions to locate a large example of the figure which is placed on the floor.
Curated OER
Manipulative Mania
Students explore tangram vocabulary and tangram designs, creating an art design that contains various geometric parts. They complete a checklist titled, Important Thing About a Quilt Design.
