Big and Small

About Big and Small

The same picture appears three times at three different sizes, and the game asks for the biggest or the smallest. Because every picture is identical, only size can decide — which is exactly the skill being practised. No timer, no way to lose; a wrong tap simply wobbles and waits.

Big and Small is one of our numbers & maths games for kids. This one plays in the iPhone and iPad app rather than in the browser, but 33 of our games are free to play right here — browse the full library to find them. It is also in our games for toddlers and preschoolers collection.

How to Play

• Read (or listen to) what the game asks for: biggest or smallest.
• Tap that picture.
• A new set appears each time.

Tips & Tricks

• Hold two fingers up to compare heights.
• Ask ‘which one is bigger?’ about things around the room afterwards.
• The question swaps between biggest and smallest, so listen each time.
