Rabbit measures a pretend path with equal-length sticks. Units must have the same size for the count to mean something. Leave no gaps and do not overlap them.

What you will discover

Measurement compares a length with repeated equal units.
Start at the same endpoint and place the units end to end.

English vocabulary

measure: đo
length: độ dài

Let’s play
