Free Printable Number Words Worksheets for Class 3

Third graders typically work on mastering number words up to 1,000 and are often introduced to writing numbers into the thousands (e.g., 1,250 or "one thousand, two hundred fifty"). The focus is on solidifying the patterns for larger numbers.

Use a place value chart that includes the thousands period. Teach students to read the number to the left of the comma first ("one"), say the period name ("thousand"), and then read the remaining three-digit number as they learned in second grade ("two hundred fifty").

A frequent mistake is misplacing or omitting the word "thousand." Students may also struggle with the proper use of commas or revert to incorrect forms like writing "twelve hundred" instead of "one thousand, two hundred."

In third grade, this skill moves into practical application. Students can practice by writing out numbers found in word problems, reading large numbers from science or social studies texts, or in real-world contexts like understanding monetary amounts.

These worksheets are available as printable PDFs and in a digital format. The printable version is great for focused, offline practice, and you can grade submissions quickly using the Wayground for Teachers app. Each worksheet also includes a full answer key.

While third-grade math shifts to multiplication and fractions, strong number sense remains the foundation. Mastering number words for large numbers prepares students for the fourth-grade Common Core standard (4.NBT.A.2) of reading and writing multi-digit whole numbers in various forms.
