The Marshmallow Geometry Unit is an engaging and challenging lesson reviewing 2D and 3D geometric vocabulary and concepts. Students will enjoy this hands-on experience in math as they create 2-dimensional and 3-dimensional shapes using marshmallows and toothpicks. Students will also use their problem solving and team building skills as they create a suspension bridge and tower. Practicing measurement and averaging skills as comes into play as different team members shoot the marshmallows from a marshmallow shooter. Students then measure the distance the marshmallow traveled and find their teams average distance.
