Match the question, answer and feedback
1 · Learn
A quiz program needs a complete question, a way to accept an answer, a decision and useful feedback. The accepted answer must match the question shown.
For a numerical question, decide how inputs such as spaces or text are handled. A visually attractive quiz can still be wrong if its stored answer belongs to a different question.
2 · Worked example
For 3 + 5, I accept the intended numeric value 8 and explain the addition. I do not reuse an answer from a previous subtraction question.
3 · Your turn
What should you test besides one correct answer in a quiz program?
Check your answer
A wrong answer, a blank answer, relevant invalid input and any boundary or formatting cases the tool supports. Check feedback and retry behaviour too.
4 · Apply your learning
Build a two-question practice quiz with original self-contained questions in an approved tool. Test every answer path and label it as a local project, not a saved website score.
Adult guidance and safety
Use adult-approved offline or school-managed tools, invented data and original media. Keep projects private unless sharing is explicitly approved. Paper traces support, but do not replace, practical programming and saved digital work. No real passwords or personal records belong in these exercises.
Open your writing and drawing pad
Write, draw or show your working. Use a mouse, pen or finger. This pad is not a submitted answer.
Not saved to your account. Download your drawing as PNG and your typed notes as TXT before leaving or refreshing. They are separate files. Do not enter private information.
Open a picture saved on this device to draw on it again. Opening replaces the drawing, but Undo can restore it. PNG only, up to 4 MB and 4096 × 4096 pixels. The picture stays in this browser; it is not uploaded. Paper lines in a saved picture become part of that picture.
Clear the drawing? Your typed notes will stay. You can undo this action.
Your pad is empty.
Open a UTF-8 TXT file from this device, up to 40 KB and 10,000 characters. It stays in this browser. Opening can be undone until you type again. Downloads keep a new copy; they do not change the file you opened.
Replace the notes on this page with the opened file? Download the current notes first if you want to keep them.
Typed notes are not submitted answers.
Check a calculation · Year 5 onward
Use this only when your teacher or adult allows a calculator for the task. Show your thinking first. It does not replace mental or written arithmetic and does not mark your lesson answer.
