The Birds

10 min

Narrative

The purpose of this Warm-up is to elicit the idea that the shape of a birdhouse can be modeled by a rectangular prism, which will be useful when students solve problems about the volumes of birdhouses in a later activity. While students may notice and wonder many things about the photograph, the shape of the birdhouse is the important discussion point.
