This three-part interactive lesson has students use spatial sense and analytical skills to investigate the parts of three-dimensional polyhedra. Students view and control animations of the solids and their nets, which help them to count faces, edges and vertices, and to establish Euler's relation among those counts. Teachers notes, worksheets and printable nets are provided.
Nice 3-lesson package By Uncle Bob on 08/22/2012 - 09:22
Nicely interactive. The lessons are learner-paced, and they use animation, color, and manipulation to show the parts of 3D shapes and their nets. This resource is worthwhile even if the Euler number is not one of your objectives.
Might need some teacher direction By path on 01/23/2013 - 11:06
Great activity, but might need some additional teacher direction for use with upper elementary students.
