lesson
A project needs a usable delivered version
1 · Learn
A project might combine a spreadsheet chart, original illustration and explanatory web page. Choose each tool for a job and keep editable source files as well as the final viewing copy. Exporting can flatten information or change layout.
Use clear headings, meaningful link text and text alternatives for informative graphics. Test the delivered version with the intended task, including keyboard and narrow-screen use, rather than judging appearance alone.
2 · Worked example
For a fictional club report, I export a labelled chart and check it remains readable in the final page. I keep the spreadsheet so the values and chart can be revised later.
3 · Your turn
Why retain an editable chart source after placing its image in a report?
Check your answer
The image may not retain editable data or chart settings; the source supports accurate later changes.
4 · Apply your learning
Build a small private multi-tool report using invented data and record one usability improvement from testing.
Adult guidance and safety
Use an approved private interpreter, simulator or authoring tool with fictional data. Trace and predict before running. Never execute unknown downloaded code, inspect real credentials or use other people's private data. Working examples still need saved-project and assessment integration before release.
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.
Powers, roots and trigonometry · Year 7 onward
Use only when the task allows a calculator. Choose one operation at a time and record your working. Trigonometry here always uses degrees (DEG), not radians. Inverse sine, cosine and tangent return an angle, not a reciprocal. Keep exact fractions and π in answers when requested.
Approximate numerical results use up to 12 significant digits. Inverse sine returns −90° to 90°, inverse cosine 0° to 180°, and inverse tangent −90° to 90°; these are principal values, not every possible solution of a trigonometric equation.
