Frequently Asked Questions

Are these math worksheets really free?

Yes. Every worksheet generator on UnitFig is 100% free with no sign-up, no watermark and no paid tier. Problems are generated in your browser and print cleanly on US Letter paper.

Can I generate unlimited different worksheets?

Yes. Every click of "New random problems" produces a fresh set, and the engine avoids duplicate problems within a sheet so students cannot memorize a fixed pattern.

Are the answers correct?

Yes. The generator is a deterministic algorithm (not AI) that computes each answer from the problem it creates, and a build-time self-check verifies 150,000 sample problems across all worksheet types. Unit-conversion answers use the exact NIST/SI constants and can be verified with the UnitFig converters.

What size paper are these designed for?

US Letter (8.5×11 inches), the standard classroom paper size in the United States. The print layout hides the controls and prints just the problems and answer key.

Do the worksheets follow school standards?

The grade presets align with Common Core State Standards math domains (for example 2.OA.B.2 for grade-2 addition fluency and 7.NS.A.2 for integer operations).
