Cup Nesting

What you need

• measuring cups or stacking cups

How to do it

1. Tip a set of measuring cups onto the floor
2. Show them the biggest one and drop a smaller one inside
3. Let them work out which fits inside which

Why it matters

Working out what fits inside what builds size judgement and the careful hand control they’ll use for puzzles.

What they're learning

Size judgement

Figuring out which cup fits inside which is early visual comparison, the same reasoning behind picking the right-size shoe or container lid later.

Hand-eye teamwork

Lowering a smaller cup into a bigger one without missing trains the precise aim used later for stacking blocks and puzzle pieces.

Trial and error

Trying a cup that doesn't fit and swapping for another teaches them to adjust rather than force it.

What to look for

Watch for them holding two cups side by side to compare size before choosing, instead of grabbing at random.

A tip

Start with just 3 cups of very different sizes — a full nesting set is genuinely tricky and can frustrate this age group.
