Tool: A Plethora of Polyhedra Review
Teacher Review (Based on classroom experience)
Reviewer: Jethro, Feb 21 2010 10:35:42:060PM
Classroom use in Courses and Topics:
Geometry: Perimeter, area, and volume
Duration of classroom use:
One Class
What did students learn?
Students learned the relationship between 3-D objects and the 2-D nets that create them. Specifically, as an intro to nets, they learned about the Platonic solids as an enrichment before learning about general nets.
What did students do with the resource?
Observed during a presentation; I might someday use the tool for individual student use but the lab requires more time than this lesson allows.
How hard was it for students to use?
Other classroom comments:
The presentation went very well. The only issue was the size of the window I could use. I had to reduce the size of the solid, especially when showing the icosahedron.
Appropriate for:
introduction to a concept, advanced investigations
What math does one need to know to use the resource?
Basic nets; basic polygons
What hardware expertise does one need to learn to use the resource?
Basic browsing, presentation equipment (if you want to show it to a classroom)
What extra things must be done to make it work?
familiarize yourself with little functions, like transparency, that you can't really play with while presenting.
How hard was it for you to learn?
The interface was user intensive... i only wish I could choose which vertex the polyhedra would unfold from. Several times I started unfolding from the back unintentionally.
Ability to meet my goals:
