Use a set of stacking or nesting cups (or plastic kitchen cups of different sizes) to build a simple tower, largest to smallest, then knock it down and rebuild. A repeatable, low-stakes building activity sized exactly for toddler hands.
What you need
- stacking cups or plastic kitchen cups of varying sizes
How to do it
- 1Spread the cups out and let the toddler explore sizes by hand first.
- 2"Which one goes on the bottom — the big one or the small one?" Guide toward largest-first if needed.
- 3Stack cups one at a time, cheering each successful addition.
- 4Knock the tower down together and start over as many times as interest lasts.
Variations
- If stacking cups aren't available: any set of nesting bowls or plastic containers works the same way.
- How it ends: no formal ending needed — this one naturally stops when the toddler moves on.
💡 Parent tip
Narrate the sizes out loud ('big cup, medium cup, tiny cup') as you go — it turns the play into quiet vocabulary building.
What your child develops
- Size sequencing — ordering objects from largest to smallest is a foundational early-math skill
- Fine motor control — placing a cup precisely on top of another
- Cause and effect — building up and knocking down is one of the earliest satisfying feedback loops
