About Kujji
A small set of tools for making printable practice material, built for the way teachers actually work: decide, configure, print.
What this is
Kujji makes printable math worksheets and printable paper. Every page on the site is the tool itself — you arrive from a search, configure what you need, and print it. There is no article to read first and no PDF to hunt for.
How the sheets are made
- Everything is generated in your browser. The questions are created on your device when you click Generate. Nothing is uploaded and nothing is stored on a server.
- Answer keys come from the same source as the questions. The two pages are rendered from one set of data, so they cannot disagree.
- Printable paper is drawn in physical units. Grids are specified in inches and millimetres rather than pixels, so a quarter-inch square is a quarter inch on paper.
- Letter and A4 are laid out independently. Neither is a scaled version of the other, so margins and page breaks are correct on both.
What we do not do
- No accounts. You do not need to sign up, and there is no email capture to print a sheet.
- No paywall on the basics. Printing a worksheet with an answer key is free.
- No copied material. Every question is generated by the tool. We do not reproduce worksheets, answer keys or artwork from other publishers.
- No data about children. The tools never ask for a pupil name, and nothing a child types is sent anywhere. The name line on a printed sheet is filled in with a pen.
- No advertising in the way of the tool. If advertising ever appears, it will not sit between you and the Print button.
Corrections
If a question or an answer key is wrong, that is the most serious kind of bug on this site. Tell us which sheet, which settings and which seed — the seed is printed in the sheet footer — and it can be reproduced and fixed exactly.
Using the sheets
You may print as many copies as you need for the pupils you teach, at school or at home. You may not resell the sheets, republish them as your own, or mirror the tools on another site. If you want to link to a sheet, link to the page and use Copy link to capture the exact configuration — that is what it is for.
