What this lesson shows
Sticks and clay balls build a triangle and a square: count the sticks for sides and the balls for corners, then draw it.
The worked example
The lesson works this one step by step: square (question 1). Then your kid tries one like it on paper.
The steps
- Sticks make the sides
- Balls make the corners
- Triangle: 3 sticks, 3 balls
- Square: 4 sticks, 4 balls
Helping at home
Read each box aloud. Your kid draws a straight line from ball to ball, then counts the sides or corners. Build it for real too: straws or toothpicks with clay or play dough.
If your kid gets stuck
A stick for each side. A ball for each corner.
Watch it with Lux
