What this lesson shows
Two circles that overlap: red things in one, thick things in the other. A red, thick block goes in the middle, where both are true; a thin blue one goes outside both. A yes-no chart asks one question: is it red?
The worked example
The lesson works this one step by step: red thick 2, red thin 1, blue thick 1, blue thin 1. Then your kid tries one like it on paper.
The steps
- One circle for each rule
- Both true: the middle. Neither: outside
- Count each part
- A yes-no chart asks one question
Helping at home
Plain blocks are red; blocks with a dot are blue. Read each box aloud. Your kid draws two circles that overlap, red in one and thick in the other, and puts each block where it fits: both in the middle, neither outside. Then a yes-no chart: is it red? Sort toys by two rules the same way.
If your kid gets stuck
Both true: the middle. Neither: outside.
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.
