Roll, Slope, and Slide (A Book About Ramps) by Michael Dahl & Denise Shea

In Roll, Slope, and Slide, Michael Dahl introduces children to ramps, slopes, and inclined planes through familiar examples like playground slides, skateboards, and roller coasters. Bright illustrations and simple explanations help children notice how ramps make movement possible and how objects can roll, slide, or stay put depending on the surface and slope. This title pairs well with Kodo materials that invite children to build pathways, adjust steepness, test motion, compare materials, and revisit their ideas through playful investigation. It gives educators an easy way to connect children’s ramp play with the simple machines they encounter every day.

Appropriate for children ages 4+.
