The lesson was informative but short, so they were really able to retain the information and answer questions I asked them about what they learned about polar bears. Drawing the polar bear was also educational because we were learning about measuring, how to follow a blue print, and team work.

As a homeschool mom I love the idea of making life-sized or scale drawings for the kids to supplement their learning. Especially because they’re at the age where a visual aid will work so much more effectively than just words on a page. Plus, they love sidewalk chalk so this is going to be a great way to get them more engaged with the material.
