Terms of use.

Using generated worksheets

You may generate, print and share Numberleaf worksheets and answer keys for classroom, home and tutoring practice, including paid lessons. Attribution is appreciated but not required on the printed sheet. Do not present our website or unchanged worksheet collections as your own original product, or resell access to this free website.

Choose suitable practice

The site offers mathematical exercises, not learner assessment or professional educational advice. Presets are not curriculum, grade or year-group certifications. Check the selected range, notation and answers before using a sheet, and consider the learner’s needs. Long-division keys give final answers rather than complete worked methods.

Service and output limits

The generator uses nonnegative whole numbers and positive proper fractions within its displayed limits. Repeated questions can occur. Reproduction requires the same seed, normalised settings and generator version; future versions may change the output. Download and print results depend partly on your browser and device.

We aim for accurate output and test the core rules, but cannot promise uninterrupted service or that no error will occur. If you find an issue, retain the skill, settings, seed and question number. See the help page for troubleshooting and support availability.

Responsible use

Do not place personal or sensitive details in seeds, misuse the website or attempt to disrupt hosting. Questions are generated locally, so no account or submission is needed. Your use of external sites, browsers and printing services is subject to their own terms and practices.

Changes

These terms describe the first release. We may improve features or revise resource permissions, with an updated notice here. No purchases or subscriptions are part of this release.
