How it works
Stack same-size blocks one on the next, as tall as the thing. Then count them.
The blocks must all be the same size.
Start at the bottom and go up with no gaps.
Worked examples
Measure a can
- Stack blocks beside a can until they are as tall.
- Count them: 1, 2, 3, 4.
- The can is 4 blocks tall.
A fair way
- All the blocks are the same size.
- That makes it a fair measure.
- Different sizes would not be fair.
Try it
- Measure a cup with the same blocks.
- Stack and count.
- Say how many blocks tall.
