Welcome to Ohio! We're glad you could stop by! While you are studying your state's geography, facts and symbols, this activity will integrate art, math and fun into your unit. Your students will create a dodecahedron. Since a dodecahedron is a 3-dimensional, 12-sided shape, each side will be used to represent a symbol from your state. For display, hang these little guys from the ceiling. They are sure to brighten up any hallway or classroom.
