5 minutes

What you'll need

Two purpose-made under-3 matching containers with permanently attached lids

Before you start

Can manipulate large household objects

Best fit: indoors · medium energy · low caregiver effort · low mess

How to play

  1. Mix the lids beside the containers.
  2. Let your child try first.
  3. Offer a small hint only if frustration grows.
Make it easier

Use one container and one lid.

Standard

Offer two containers and lids for trial-and-error matching.

Extend it

Add a third container or compare big and small.

What you might notice

Turning, checking and changing strategy after a mismatch.

Keep it safe

Use only intact purpose-made under-3 matching containers with lids that cannot detach, snap on fingers or trap a hand. Stay within arm's reach, stop mouthing or damage, and count and store both containers.

Why it may be useful

This gives your child room to explore while you add just enough help to keep the puzzle interesting.
