This product can be used to reinforce 3D shapes. I gave my students mini marshmallows (you could also use gum drops, Dots candy, etc.), toothpicks, and pipe cleaners (I cut the pipe cleaners in half). Students were to construct various 3D shapes using the marshmallows, toothpicks and pipe cleaners, trace the name of the shape, and record the amount of each material they used on their paper. Included in this product is a recording sheet and quiz.
