What this lesson shows
Fixes a mistake
A big circle and a small circle go together. Big or small, turned or not, the shape stays the same.
The worked example
The lesson works this one step by step: circle (question 1). Then your kid tries one like it on paper.
The steps
- Look at the sides
- Ignore the size
- Same shape, same group
- Big or small, still the same
Helping at home
Read each box aloud. Your kid finds every one of that shape, big or small. Ask "is the small one a circle too?"
If your kid gets stuck
Big or small, it is the same shape.
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.
