lesson
The audience changes the choice
1 · Learn
Email, messages, shared documents and video calls serve different communication needs. A shared document can support asynchronous editing; a live call requires participants at the same time. Choose a school-approved channel for the purpose and audience.
Access permission matters as much as the channel. A public link and an invited private group have different exposure. Do not assume a friendly display name proves someone's identity.
2 · Worked example
For classmates editing a fictional project at different times, I propose an approved shared document with restricted access, rather than publishing everyone's notes publicly.
3 · Your turn
Why is a public link not the same as permission limited to named collaborators?
Check your answer
Anyone who obtains a public link may be able to access it, depending on settings; restricted access checks authorised users.
4 · Apply your learning
Compare three fictional communication tasks and justify the audience, timing and permissions for each.
Adult guidance and safety
Use a school-approved offline or supervised tool and fictional data. Keep work private, respect media permissions and check accessibility. Paper traces support understanding but do not replace running, saving and testing a real project. Do not enter passwords, addresses or other personal details into 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.
