Measuring with Hands and Cubes

Goal: Measure length using the same unit again and again (hand spans, blocks, paper clips) and compare results.

For parents: The big idea: units must be the same size and have no gaps. Once children see why, rulers make sense.

Do together

  1. How many blocks long?

    You need: Building blocks or dominoes, a shoe, a book, a spoon

    Line blocks along each object with no gaps. Count them. Which object was longest?

  2. Footsteps across the room

    You need: The room

    Walk heel-to-toe across the room and count your steps. Then an adult does it. Why are the numbers different?

  3. Paper-clip worms

    You need: Paper clips, strips of paper cut to different lengths

    Measure each paper 'worm' with a chain of clips. Order the worms from shortest to longest.

Talk about it

  • Why did Abba need fewer steps than you?
  • What happens if we leave gaps between the blocks?
  • Which is longer: 6 blocks or 9 blocks?
