What this lesson shows
Sort the solids: a sphere rolls, a cube stacks, and a cylinder does both.
The worked example
The lesson works this one step by step: cylinder (question 1). Then your kid tries one like it on paper.
The steps
- A sphere rolls
- A cube stacks
- A cylinder does both
- Sort by what they do
Helping at home
Read each box aloud. Then test real things: does a ball roll? Does a block stack? A can does both. Your kid sorts them into "rolls" and "stacks".
If your kid gets stuck
Round parts roll. Flat parts stack.
Watch it with Lux
With Lux, this lesson is a narrated video and a printed page your kid works on. Then Lux helps with the same math on their own worksheet, one question at a time.
