This document outlines a lesson plan on polygons. The lesson will classify polygons by number of sides, differentiate regular and irregular polygons, and identify common polygons like triangles, quadrilaterals, and polygons with 5 or more sides. Students will play identification games with flashcards and shapes around the classroom. They will then sort shapes into regular and irregular polygons. The lesson aims to teach students about different types of polygons and identify examples of polygons used in daily life. An assessment matching polygons to their names and identifying regular and irregular shapes is included.
