How these worksheets are made

Every answer is checked by computer, not by eye. Each worksheet is generated from a program that recomputes every answer — with exact fraction arithmetic, or against the real trigonometric values — before the PDF is written. If one answer disagrees, no file is produced.
Worked keys, not answer lists. The key shows the steps, not just the final value, so a student can find where they went wrong.
Built to print. US Letter and A4 versions of every sheet, and nothing depends on colour — they stay readable in black and white.
Proper mathematical typesetting. Fractions are stacked, radicals and exponents are set correctly, and nothing is written as plain text like 3/4.

Frequently asked questions

Are these worksheets free?

Yes. Every worksheet is free to download, print and use in a classroom. No sign-up and no account.

Do the worksheets include answers?

Yes. Every PDF ends with a worked answer key covering all of its questions, showing the working rather than only the final answer.

Can I print these on A4 paper?

Yes. Every worksheet is offered in both US Letter and A4, laid out separately for each so nothing is cut off or scaled down.

What grade or level are these for?

They are organised by skill rather than by grade, so you can pick the set that matches what a student is working on. The fractions sets suit upper elementary and middle school; the algebra, geometry and trigonometry sets suit Algebra 1 through Precalculus.

Can I use these with my class?

Yes. Print as many copies as you need for your own students.
