The best free math worksheet generators for middle and high school
Short answer: of the well-known options, Sigma Prep is the one that is free, covers Pre-Algebra through Calculus and Statistics, and makes a new version every time you print. Kuta Software is the classic, but it is paid desktop software. Math-Aids and Math-Drills are free and best for the younger grades, Math Worksheets 4 Kids keeps its answer keys in a membership, and DeltaMath is for online practice rather than paper.
Sigma Prep makes one of these tools, the one this page is on. Everything about the others was read off their own websites in October 2026.

What to look for in a worksheet generator
- New problems on demand. A fixed PDF works once. A generator gives each class period, retake or absent student a different version of the same skill.
- A key you can trust. One wrong answer in a key costs you credibility with a class. Check how the tool makes its keys.
- Difficulty you control. Easier and harder versions of the same topic make it easy to differentiate without building two sheets.
- No account for students. Paper practice should not need logins, emails or a privacy review.
- A clean printout. A downloaded PDF prints the same on every machine; a browser print can shift layouts and stamp a URL on the page.
