We continued our exploration of geometric shapes this week using Power Polygons and Geoboards. We played the game “What’s my rule?” to focus on characteristics of the shapes. Then we concentrated on triangles and what makes a triangle. The biggest hit was making triangles on geoboards! The students worked together to make as many triangles as possible by connecting their geoboards. They go up to twenty-nine boards and then we ran out of rubber bands. They also discovered that it takes the same amount of time to make shapes on a geoboard as it does to take them off.
