Free Math Worksheets for Grade 3

These worksheets provide additional calculation practice for many third grade math topics, following the Common Core standards and Math Mammoth grade 3 curriculum. Use them as you need!
The worksheets are generated automatically each time you click on the links below.
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 in the Print Preview, adjust your
margins, header, and footer in the Page Setup settings of the browser. Or,
adjust the "scale" to 90% or less in the Print Preview. Some browsers
may have "Print to fit" option, which will automatically scale the worksheet to
be so small as to fit the printable area.
The problem sheets are randomly generated, so you can get a new, different one just by hitting
the refresh button on your browser (or F5).
