This activity is a hands-on activity to deepen understanding of polygons. Students use a Tangram set to create a polygon with the specified number of pieces. Students must use their geometrical and spatial reasoning as well as their knowledge of polygons in order to solve each challenge. There is also a Tangram cut out provided for those who don't already have Tangram sets. This activity can be used for a variety of grade levels and is a great use of manipulatives to improve a student's understanding of Geometry.
