  • Mix together 20-30 small objects: coloured pompoms, buttons, dried pasta shapes, pegs, small erasers.
  1. Set out a 6 or 12-cup muffin tin on a table or tray.
  2. Mix together 20-30 small objects: coloured pompoms, buttons, dried pasta shapes, pegs, small erasers.
  3. Dump the pile beside the muffin tin: 'What a muddle! Can you sort them out?'
  4. Do not give instructions on how to sort — let your child decide their own system.
  5. Watch from a distance. If they ask for help: 'You decide — where do you think that one goes?'
  6. Some children will sort by colour, some by size, some randomly. All approaches are valid.
  7. When the tin is full: 'Look! Every cup has something in it! How did you decide where they go?'
  8. Tip them all out and invite them to sort again: many children will choose a completely different system the second time.

Parent tip

Set out pom poms before inviting your toddler in so the first minute feels smooth.

What success looks like

Intense focus, even briefly. Watch for the small ‘aha’ moment when they figure out how something works.

Take a muffin tin and dump a mixed pile of small objects beside it: pompoms, buttons, pasta shapes, beads, coins, pegs. Your child sorts them into the compartments however they choose — by colour, by size, by type, or by their own mysterious logic. The muffin tin provides built-in structure that guides the activity without adult instruction. This is the quintessential Montessori transfer activity, and children will often repeat it multiple times.

Why it helps

Sorting is a foundational mathematical skill — classifying objects by attributes (colour, shape, size) is pre-number thinking that the EYFS Mathematics framework identifies as key for this age. The Montessori approach to transfer activities like this builds concentration, hand-eye coordination, and independence simultaneously. Research shows that self-directed sorting (where the child chooses the classification system) develops higher-order thinking more effectively than adult-directed sorting, because the child must create and test their own categories.

Variations

  • Add tongs, tweezers, or a spoon for transferring — changes the fine motor challenge significantly.
  • Colour-code the cups: put a small coloured dot of paper in the bottom of each cup and challenge the child to match objects to colours.
  • Use natural materials: acorns, pebbles, shells, leaves — sorting outdoors adds a nature element.

Safety tips

  • Assess choking hazard risk for your child's age — buttons, coins, and dry pasta are not safe for children who still mouth objects.
  • For under-twos, use only large pompoms, chunky pegs, and objects bigger than a golf ball.
  • Supervise periodically — the novelty of many small objects can tempt children to hide them in ears, noses, or pockets.
