Free Printable Math Worksheets for Grade 3

This is a comprehensive collection of math worksheets for grade 3, organized by topics such as addition, subtraction, mental math, regrouping, place value, multiplication, division, clock, money, measuring, and geometry. They are randomly generated, printable from your browser, and include the answer key. The worksheets support any fourth grade math program, but go especially well with IXL's 3rd grade math curriculum.

The worksheets are randomly generated each time you click on the links below. You can also get a new, different one just by refreshing the page in your browser (press F5).

You can print them directly from your browser window, but first check how it looks like in the "Print Preview". If the worksheet does not fit the page, adjust the margins, header, and footer in the Page Setup settings of your browser. Another option is to adjust the "scale" to 95% or 90% in the Print Preview. Some browsers and printers have "Print to fit" option, which will automatically scale the worksheet to fit the printable area.

All worksheets come with an answer key placed on the 2nd page of the file.

Mental multiplication

I believe in a method I call structured drilling of the multiplication tables. It is not random at first, but students practice the tables based on the patterns in the tables — and (VERY IMPORTANT) they practice the tables "backwards" also. Worksheets can be used for random drilling after the initial stage of structured drilling.

Skip-count by 3, starting from 3
Skip-count by 4, starting from 4
Skip-count by 5, starting from 5

Skip-count by 8, starting from 8
Skip-count by 9, starting from 9
