2-D Objects and Their Properties

One of the most exciting aspects about this lesson besides the construction of various area formulas, is the connection to one of Tiffany Neill’s Environmental Science lessons, “Reduce, Reuse, Recycle.” I’d love to hear from those of you who engage your students with these lessons as part of a larger environmental or recycling theme.

This lesson really emphasizes the context of the environment as students explore how much trash can fit into landfills. With such a multi-faceted question, this lesson first focuses on areas of 2-D objects, allowing students to develop there own visual and kinesthetic proofs.
