This is an interactive activity that allows students to demonstrate their understanding of the number of faces, edges, and vertices on a three dimensional figure. There is also an image select game. One of 18 - 3 D images along with either # of faces, # of edges, or # of vertices will flash on the screen. The student will touch the flashing objects and 3 answers will appear. The student must answer the question correctly. Immediate feedback is provided. This activity could be used individually, small group or whole class.
