What this lesson shows
Fixes a mistake
A pencil drawn higher up looks taller. Line up the bottoms, and it is the shorter one.
The worked example
The lesson works this one step by step: towers, 6 and 4: which is taller. Then your kid tries one like it on paper.
The steps
- Higher up is not taller
- Put them on the same floor
- Line up the bottoms
- Then compare the tops
Helping at home
Read each box aloud. Then try it: a short toy on a stool next to a tall toy on the floor. Which is taller? Put both on the floor to check.
If your kid gets stuck
Line up the bottoms first.
