These were new concepts for the Geometry Common Core Standards, so I wanted a creative way to teach it! My students LOVED this activity and it truly led to them mastering the two concepts. It also meant for a memorable activity. When we did these problems at the end of the year for review, I would simply have to say the Play Doh Activity and all of the students instantly remembered.
All of the materials needed for the activity are included in the directions. I ordered a large pack of small Play Doh containers. If you have big classes, you could always have the students work in pairs or small groups too. Dental floss worked well for actually performing the slices to see the cross sections of the three-dimensional shapes.
