Big and Small

Parent and child compare quantities, sizes, and lengths of everyday objects. The agent coaches the parent to observe the child's use of comparison language, understanding of more/less, and ability to order objects by size.

What you'll need

3-4 objects of different sizes. Two groups of countable items in different quantities. Clear workspace.

How it works

  1. 1~20s

    Hold up two objects — one big, one small (like a big shoe and a small shoe, or a big cup and a small cup). Ask your child: 'Which one is BIGGER?' Then: 'Which one is SMALLER?' Does they point correctly? Can they use the words 'bigger' and 'smaller'?

    Watch for: Child correctly identifies bigger and smaller objects.

  2. 2~25s

    Now put two groups of items side by side — maybe 2 blocks and 5 blocks. Ask your child: 'Which group has MORE?' Then ask: 'Which has FEWER?' or 'Which has LESS?' Does your child know which pile has more without counting?

    Watch for: Child correctly identifies which group has more and which has fewer.

  3. 3~25s

    Last challenge — give your child three or four items of different sizes and say 'Can you put them in order from smallest to biggest?' This is called seriation and it's a more advanced comparison skill. How does your child do?

    Watch for: Child orders items by size from smallest to biggest or vice versa.
