Comparing three-digit numbers means figuring out which number is bigger, which is smaller, or whether they are equal to each other. In Grade 2, you work with numbers from 100 all the way up to 999, learning to line them up and compare step by step. The smart way to compare is to start at the biggest place: the hundreds. If the hundreds digits are different, the number with more hundreds wins every time. If the hundreds match, look at the tens next. If the tens also match, compare the ones. We write these comparisons using three special symbols: > means greater than, < means less than, and = means equal to. A fun trick is the alligator mouth: the open side always faces the bigger number because the hungry alligator wants to eat the larger amount. So 345 > 234 and 234 < 345. When both numbers have the same digits in every spot, we use an equal sign like 256 = 256. In Grade 3, you will stretch this same thinking to four-digit numbers up to 9,999.

Common Mistakes to Watch For
- Comparing the ones place first instead of the hundreds. Students see 189 and 231 and say 189 is bigger because 9 is more than 1, but 231 has more hundreds so it is bigger.
- Flipping the > and < symbols. Students write 234 > 345 when they mean 234 < 345. Remember the alligator's open mouth always faces the larger number.
- Forgetting to use the equal sign when two numbers are exactly the same. If both numbers have matching hundreds, tens, and ones, the correct symbol is =, not < or >.
Frequently Asked Questions
Which place do I look at first when comparing three-digit numbers?
Always start with the hundreds place. The number with more hundreds is larger. Only move to the tens if the hundreds are the same, and only move to the ones if the tens are the same too.
What do the symbols >, <, and = mean?
The > symbol means greater than, so 5 > 3 means 5 is bigger. The < symbol means less than, so 3 < 5 means 3 is smaller. The = symbol means equal, so both sides are the same.
What is the alligator trick?
Pretend the > or < symbol is a hungry alligator's mouth. The mouth always opens toward the bigger number because the alligator wants the biggest snack. So 7 > 4 shows the mouth eating the 7.
How do I compare 456 and 459?
The hundreds are the same (4 and 4). The tens are the same (5 and 5). So look at the ones: 6 and 9. Since 9 is bigger, 459 is greater. Write 456 < 459.
Can two three-digit numbers be equal?
Yes. If every place value matches, the numbers are equal. For example, 325 = 325 because both have 3 hundreds, 2 tens, and 5 ones. Use the = sign for equal numbers.
