I have used this organizer so many different ways. I have had students look at geometric solids as they fill it in, fill it it based on memory and even fill it is as they make some of the geomtric solids with toothpicks and marshmallows.
Students can work independently or in small groups.
I have included the most common geometric solids. I have also left one extra space on the organizr for you to add an additional solid that isn't listed if needed.
