Teaching tips and what to try next

Use this after second graders can name the hundreds, tens and ones in a number. Building both numbers with base-ten blocks makes the hundreds-first rule easy to see when a pair is close. Review the two-digit version in Comparing Two-Digit Numbers (>, <, =), and see the standard explained at 2.NBT.A.4.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

Second graders learn to compare three-digit numbers by looking at the value of each digit. This second-grade worksheet gives fifteen pairs of numbers from 100 to 999, and children write the greater than, less than, or equal symbol in the circle between them.

The pairs are planned to practice every step of comparing. In some pairs, the hundreds digits are different, so the hundreds place decides. In other pairs, the hundreds digits match, so children must look at the tens. In the trickiest pairs, the hundreds and tens both match, and only the ones digit is different, such as 472 and 476. Two pairs on every page are the same number, so children also practice the equal sign. Each of the ten versions has new pairs and its own answer key.

How to use it: teach your child to compare from left to right. Point to the hundreds digits first and ask which is bigger. If they are the same, move to the tens, and then to the ones. Watch for children who decide by the last digit or by which number "looks" bigger; for example, 309 is less than 390 even though 9 is a big digit. A simple way to remember the symbols is that the open side of the symbol always faces the greater number. Base-ten blocks can help when a pair is confusing: build both numbers and compare the hundreds flats first.

The answer key shows the correct symbol for every pair. For two-digit practice, try our Comparing Two-Digit Numbers (>, <, =) worksheet. For place value, try our Hundreds, Tens, and Ones Place Value worksheet.
