Instructions

Get ready
  • Set out a clean ice cube tray on a table.
  • Fill a small bowl with a mix of items: pompoms, dried pasta, large beads, small erasers, buttons (appropriate to child's age).
  1. Set out a clean ice cube tray on a table.
  2. Fill a small bowl with a mix of items: pompoms, dried pasta, large beads, small erasers, buttons (appropriate to child's age).
  3. Show them: 'Can you put one in every hole? Let us fill the whole tray!'
  4. Step back and let them work. Some will place one per compartment, some will fill randomly — both are fine.
  5. If they want to use tools: offer a spoon or tweezers for an extra challenge.
  6. When the tray is full: 'Every hole has something! Shall we tip them out and try again?'
  7. Tip the items back into the bowl and let them refill — repetition is key.
  8. For older toddlers, add a sorting element: 'Can you put all the red ones in one row and all the blue ones in another?'

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.

The small compartments of an ice cube tray are irresistible to toddlers. Set it beside a bowl of mixed small items and watch them fill each compartment with focused precision. The pincer grip, the one-to-one correspondence (one item per hole), and the satisfying completeness of a fully filled tray combine to create an activity that holds attention beautifully. Empty the tray, mix the items, start again.

Why it helps

One-to-one correspondence — placing one item in one compartment — is a foundational pre-mathematical concept that the EYFS Mathematics framework identifies as a precursor to counting. The precise placement required develops visual-motor integration and the three-jaw pincer grip that occupational therapists identify as essential for pencil control. The self-directed nature of the activity builds the concentration and independence that Montessori educators associate with deep learning.

Variations

  • Use water and a small dropper or pipette to fill the compartments — one drop at a time for fine motor precision.
  • Freeze the filled tray and pop out the frozen items the next day — a surprise reveal that extends the activity over two sessions.
  • Use a muffin tin for larger items with younger toddlers — the bigger compartments are easier to target.

Safety tips

  • Assess all items for choking risk — buttons, beads, and dry pasta are not safe for children who still mouth objects. Use large pompoms for under-threes.
  • Supervise periodically to ensure items stay in the tray and bowl, not in mouths, noses, or ears.
  • Ensure the ice cube tray has no sharp edges — flexible silicone trays are safest.
