How long is it? We can measure with blocks! Lay blocks end to end, with no gaps, and count them.
Key idea
Line up blocks with no gaps and count them to measure.
Worked example: A blocky snake
The snake is as long as 5 blocks. How long is it?
- Count the blocks under it: 1, 2, 3, 4, 5.
Answer: 5 blocks long
For the grown-up: Measure things around the house with blocks, paper clips or your child’s feet. Show how to keep the blocks touching, with no gaps and no overlaps. Short and happy beats long. Five minutes is a good lesson.
- Try it at home: Measure a table with steps heel to toe.
- How many blocks long is a spoon?
- Measure a teddy bear with paper clips.
