For teachers
Practice, homework and re-tests — ready in a minute
Pick a grade and topic and get a printable worksheet with an answer key you can trust, because every answer is checked by code. Make an easy, medium and hard version for the same lesson, run a quick live quiz, or print a fresh copy for a re-test so nobody can copy last week's answers.
How it helps
Differentiate in one click
The same topic at easy, medium and hard difficulty, so every group in a mixed-ability class works at the right level — with matching answer keys.
Create a worksheet →Bell-ringers and exit tickets
Five questions on today's topic take seconds to make. Check understanding at the start or end of a lesson and plan tomorrow from the results.
Exit ticket ideas →Live quizzes without student accounts
Students join on their own phones or laptops with a code — no sign-ups. Questions are marked automatically and you reveal answers together.
Start a live quiz →Fresh copies for re-tests
Generate a new version of any worksheet with different numbers and questions, so a re-test measures learning, not memory.
How to differentiate →Your own worksheets, cleaned up
Type or draw a custom worksheet, or photograph a handwritten one and turn it into a clean PDF and Word document.
Build a custom worksheet →Draw for the class
Share a live whiteboard: students see your working on their screens as you explain it.
Open the whiteboard →A 10-minute weekly routine
- 1On Monday, make an easy, a medium and a hard worksheet for this week's main topic.
- 2Use five questions from the medium sheet as a bell-ringer on Tuesday to see who's ready for what.
- 3Hand out the right level for independent practice; students self-mark with the answer key.
- 4On Friday, run a 10-question live quiz on the topic and note who needs another go.
- 5Print a fresh version for anyone who needs a re-test next week.

Questions
Are the answer keys really correct?
Yes. Math questions and answers are produced together by code, and English and Science questions come from reviewed question banks. Nothing is guessed by an AI model.
Do my students need accounts?
No. Students join live quizzes and whiteboards with a code. Only the teacher needs an account to create worksheets.
Can I print in A4 or US Letter?
Yes. Use Print or Save as PDF; worksheets are laid out to fit both sizes, with the answer key on its own page.
Which grades and subjects are covered?
Math, English and Science for grades 1–12 — more than a hundred topics, each at three difficulty levels.
