How it works
Three steps to a finished worksheet.
Add your student
Name, grade, and what you want them to practice. That's it.
Request the sheet
Pick topics like 'prime numbers' or 'phonics blends.' Every sheet is built fresh for that student and reviewed for accuracy before you see it.
Send or print
Email parents a one-file link, print it, or hand over a tablet. The sheet runs offline from then on — no setup on the student's end.
What's inside
Designed for classrooms and kitchen tables alike.
Works anywhere, no internet
A single HTML file. Runs in any browser, on Chromebooks, tablets, old laptops — even fully offline.
Self-checking problems
Students get instant feedback as they go, so they can catch and correct mistakes on their own.
Personalized by name and level
Each sheet addresses the student by name and targets the exact topics and grade you pick.
Reviewed for correctness
Every problem is checked against an independent answer key before delivery. No rogue math or typos.
Community library
Browse and save sheets other teachers have shared — sorted by grade, skill, and popularity.

FAQ
Questions teachers usually ask.
Do students need an account or internet?+
No. Each worksheet is a single HTML file that runs entirely in the browser. You can email it, print it, or drop it on a USB stick. Once it's on the student's device, no connection is needed.
How do I know the problems are correct?+
Every worksheet is checked against an independent answer key before it reaches you. If anything looks off, the system re-generates just that section — you never see broken problems.
Can I edit or regenerate a worksheet?+
Yes. You can regenerate the whole sheet with different topics, or swap a single section from the community library. We're also adding inline section-level regeneration soon.
Is student data stored anywhere?+
Only the names and grades you add to your own roster. Student worksheets contain no tracking, no analytics, and no personally identifying information beyond the student's first name on the cover.
What happens if I cancel?+
You keep access to everything you've already created. Downloads never expire. Paid features simply pause until you resubscribe.
