Geometry 1 - Classifying Polygons teaches students how to use the properties of polygons to classify them into groups. Students learn to identify polygons according to the number of sides they have. They also learn to identify which polygons are regular and which are not regular. There is a title slide, focus slide, objectives, vocabulary, concept development, step-by-step demonstrations, guided practice, checking for understanding, and a reward slide at the end. For best results, students should have white boards and dry erase markers.
