This geometry math activity reviews basic geometric shapes including: triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, and decagon. The activity was designed for an interactive bulletin board, but can also be used as a mini-lesson or math center. There are also programmable cards to add any other shapes that you would like to review. This also makes the activity flexible to allow for differentiation. Additionally, there are three worksheets to check individual student understanding (one covering triangles, one on quadrilaterals, and one on polygons). The answer keys are also included.
