The hungry crocodile always eats the bigger number! Place the >, <, or = sign between two numbers up to 100. A fun animated crocodile turns to face the larger number after each answer.
Choose Difficulty and Mode
Pick Easy (1–20), Medium (1–50), or Hard (1–100). Then select 60-Second Chomp or Survival (3 lives).
Look at Both Numbers
Two numbers appear on either side of a hungry crocodile. Compare them carefully.
Choose the Right Sign
Tap < if the left number is smaller, > if it's bigger, or = if they're the same. Remember: the crocodile always opens its mouth toward the bigger number!
Watch the Croc Chomp!
If correct, the crocodile turns and chomps the bigger number. Keep feeding the croc to build your score!
Hungry Crocodile Visual
An animated crocodile sits between two numbers. After you choose the correct sign, the croc turns to face (and chomp!) the bigger number — reinforcing the classic classroom mnemonic.
Three Colorful Sign Buttons
Blue < button, purple = button, and orange > button are large and easy to tap. Keyboard shortcuts (1, 2, 3 or <, =, >) enable fast desktop play.
Three Difficulty Levels
Easy compares numbers 1–20 with obvious differences. Medium uses 1–50 with closer values. Hard covers 1–100 with tricky near-equal pairs that require careful comparison.
Equal Pairs Included
Some rounds present equal numbers, requiring the = sign. This prevents students from always guessing > or < and builds complete comparison fluency.
Crocodile Chomp is a number comparison game that uses the classic 'hungry crocodile' mnemonic to teach greater than (>), less than (<), and equal to (=) symbols. Two numbers appear on screen with an animated crocodile between them. The player must select the correct comparison symbol. The crocodile's open mouth always points toward the larger number — just like the > and < symbols. This visual connection helps young learners remember which way the symbol faces. The game includes equal pairs to build complete comparison skills, and three difficulty levels let it grow with the student.
Classic Mnemonic Made Interactive
The 'crocodile eats the bigger number' trick is used in classrooms worldwide. This game brings it to life with an animated croc that visually reinforces the connection between the symbol direction and number magnitude.
Builds Number Sense
Quickly comparing numbers is a foundational skill. On harder difficulties, numbers are close together (like 47 vs 49), requiring genuine place-value understanding rather than just visual size.
Includes Equality
Many comparison games only use > and <. By including = pairs, this game ensures students learn all three relationships and don't develop the misconception that numbers are always different.
Fast-Paced Practice
The 60-second mode encourages rapid mental comparison — building automaticity. Students who can quickly compare numbers perform better in ordering, rounding, and estimation tasks.
The crocodile (or alligator) mnemonic is a beloved classroom tool. Children learn that the crocodile's open mouth always faces the bigger number — and the > and < symbols look just like an open mouth. This game brings that lesson to life.
Yes! About 15–20% of rounds present equal numbers that require the = sign. This is intentional — students need practice recognizing when numbers are the same, not just which is bigger.
On Hard difficulty, numbers can differ by as little as 1–3, making quick mental comparison challenging. For example, 67 vs 64 or 88 vs 91.
Yes! Press 1 (or <) for less than, 2 (or =) for equal, and 3 (or >) for greater than. The period and comma keys also work as > and < shortcuts.
Designed for grades K–3 (ages 5–9). Easy mode is perfect for kindergartners learning to compare single-digit and teen numbers. Hard mode challenges older students with two-digit comparisons.
