Tech Teaching Idea

My third graders have just started a polygon unit. For my lesson, I want to test their understanding of polygons, so I would split them into groups and assign each group a camera. I would have them go around the school and take pictures of different polygons found throughout. We would them come back and I would print off the pictures and the teams would have to collaborate and create a poster or other graphic organizer and explain to the class why they shapes they took pictures of are polygons (closed, no curved edges, and 3 or more sides).
