Polygons
Second graders view a PowerPoint presentation on Identifying Polygons by their number of sides and their individual properties. They separate polygon tiles into groups by their attributes.
Curated OER
Polygons and Plane Figures
Students choose a polygon to define and describe, and use Power Point and the Internet to present their polygon.
