A trick to remember < and >

The open side of the sign always faces the bigger number, like a hungry crocodile’s mouth: 7 > 3 and 3 < 7. To compare big numbers, look at the number of digits first, then compare the digits from left to right: hundreds, then tens, then units.

🐊 About this game

The signs < and > confuse many children because they look alike. The hungry crocodile solves this with a simple picture: its mouth always opens towards the bigger number. In this game, children compare pairs of numbers that grow from 20 to 100 and then to 1000, including tricky pairs such as 47 and 74, and the occasional equal pair. It quietly trains place value: to compare big numbers, look at the digits from left to right.

Best for ages 5–10
