The worksheets are randomly generated, so you can get a new, different one just by hitting the refresh button on your browser (or 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 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.

Copying permission: you can freely print and copy unlimited copies of the worksheets for use in the classroom, home, tutoring center—anywhere you might be teaching. If you want to distribute the links or worksheets on a website or publication, please contact us.
