What this lesson shows
Fixes a mistake
A pyramid on its side is still a pyramid.
The worked example
The lesson works this one step by step: a square pyramid, on its side. Then your kid tries one like it on paper.
The steps
- Turning does not change it
- Count its parts
- Stand it on a base
Helping at home
Turning a solid does not change it. Name it by its parts, not by how it sits: count the bases, look at the faces, and look for an apex.
If your kid gets stuck
Count the bases. Look for an apex.
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.
