Teaching tips and what to try next

Suits first graders who read numbers to 120 and know which digit is in the tens place. Children sometimes pick the number with the larger ones digit, so have them cover the ones with a finger and compare the tens first. Practice the comparison symbols in Comparing Two-Digit Numbers (>, <, =), and the standard page is 1.NBT.B.3.

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

Comparing numbers is about place value, not about which number looks longer or has bigger digits. In 56 and 52, the tens match, so the ones decide. In 104 and 98, the hundred makes 104 the greater number. First graders are expected to compare two-digit numbers based on the tens and ones digits, and counting to 120 means three-digit numbers just past one hundred show up too.

The page has sixteen questions. In Part A, children write the greater of two numbers, and in Part B, they write the number that is less. Numbers run from 10 to 120. Some pairs share the same tens digit, so children must look at the ones. Other pairs have different tens, and a few pair a number from 100 to 120 with a two-digit number, which helps children see why a three-digit number is greater. The two numbers in a pair are never equal. Each of the ten versions has new pairs and its own answer key.

How to use it: read each question aloud and ask your child to say which place they will look at first. If they are unsure, have them show both numbers with tens rods and ones cubes and compare the rods. A hundred chart taped to the table also helps, since the later number on the chart is the greater one.

The answer key shows the right number for every pair. For the greater than and less than symbols, try our Comparing Two-Digit Numbers worksheet. For putting numbers in order, try our Ordering Numbers and Counting to 120 worksheet.
