Conics Project - Uprate #4: Cutting, Stamping, Surgeons and Interpreters

Cutting and stamping went well!

One team was allowed to cut at a time which felt very manageable.  Circle and ellipse groups had an easier time of actually cutting through the cone but they also often had to cut twice because their first circle was too small or their ellipse looked too much like a circle.

The cutting and stamping only took about 20-25 minutes so I plan to update the project calendar for next year by having the students start the poster making sooner.

The cones are Styrofoam and purchased from a craft store.  I found them in the section with the fake flowers.  Students marked them with markers to show where they planned to cut and then sawed through the Styrofoam with a serrated steak knife.   The material sheds a bit and we had to clean up some Styrofoam dust. The paint is water soluble poster paint.  Some groups got fancy and mixed colors!




I was absent (at a workshop) for the Surgeon and Math Interpreter meetings but my co-teacher felt that the group meetings went well but the rest of the class (with my substitute) was prone to getting off task.
