A brief introduction to and overview of wedges that worked well for my elementary STEAM progam for ages 6-11. Though I did not read it aloud, the back matter includes a glossary of the bold words in the text, a list of additional books on the topic, and an index. I more or less skipped the portion about the complex machines since half of it was about earth movers and what they're used for.
