10 minutes

What you'll need

Large lightweight ball · Purpose-made low ramp, or a smooth lightweight rounded-edge board secured by the adult · Non-slip support no higher than one large block

Before you start

Child can explore a simple problem with familiar objects in their preferred position

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

How to play

  1. The adult secures and tests the very low ramp on the floor.
  2. From beside the ramp, choose a start point and predict where the ball might stop.
  3. Roll, observe, then change one feature while the adult keeps the ramp secured.
Make it easier

Roll on a flat floor toward a visible line.

Standard

Roll one large ball down a purpose-made or carefully secured low ramp and make simple predictions before changing one thing.

Extend it

Compare two large balls while keeping the ramp unchanged.

What you might notice

Notice what evidence the child uses when changing their prediction.

Keep it safe

Use a purpose-made low ramp or a smooth lightweight rounded-edge board secured by the adult to a non-slip support no higher than one large block. Test before play, keep fingers clear of contact points, and stop if it shifts. The child rolls from beside it and never stands or climbs on it.

Why it may be useful

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

Guided-play evidence is stronger in preschool samples; toddler activities should remain simple and child-led.

How it works
  • Sort by a changing rule

    Sort a small set of large familiar objects by one visible feature, then choose a different rule and sort again.

  • What comes next sequence

    Arrange three familiar routine pictures or objects and wonder together what could come next, allowing more than one sensible answer.

  • Make a map of the room

    Draw a simple map of one room together and use it to find a familiar location or object.
