Teaching tips and what to try next

Good for second graders who can read three-digit numbers aloud and name the value of each digit. Keep a small card with the tens words (twenty to ninety) nearby so spelling does not slow the place-value thinking. Expanded form is the companion skill in Hundreds, Tens, and Ones Place Value; compare numbers next in Comparing Three-Digit Numbers.

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 read and write numbers up to 1,000 with digits, with number names, and in expanded form. Writing number names is also good spelling practice for words like forty, ninety, and fifteen. This second-grade worksheet works in both directions.

In Part A, children read six number names, such as seven hundred forty-two, and write each number with digits. In Part B, they read six numbers and write the number names. Every part includes numbers with a zero in the tens or ones place, such as 506 or 830, and a number that ends in a teen, such as 418. These are the numbers that cause the most mistakes. Each of the ten versions has new numbers and its own answer key.

How to use it: teach your child to read a number in chunks. First say the hundreds, then say the last two digits as one number: 742 is "seven hundred" and "forty-two." Remind them that a zero is not said out loud, so 506 is "five hundred six." Point out the spellings that trip children up: forty has no u, and the tens from twenty to ninety end in y. In Part A, have your child write the hundreds digit first and then ask, "Are there any tens?" before writing a 0.

The answer key shows every answer. For expanded form and place value, try our Hundreds, Tens, and Ones Place Value worksheet. For the smaller number words, try our Number Words 0-10 worksheet.
