You wake up sick at 5:30 a.m. and the last thing you can face is building a lesson a stranger can teach. Media and digitalisation is actually an ideal sub-day topic, students have opinions, the material connects to their daily lives, and the discussion can run itself, but only if the plan is genuinely no-prep. This post gives you a self-contained lesson a substitute can run with zero preparation: clear timings, student-facing instructions, and a built-in product to leave nothing to chance. Print it, drop it in the sub folder, and go back to bed.
What to leave on the desk
Everything the substitute needs fits on two pages. Leave a printed set from the Media and Digitalisation – Chances and Risks unit, a class list, and this timed plan. The instructions are written to the students, not the sub, so no content expertise is required. The only sub job is to keep time, hand out paper, and collect the exit slips at the end. Write across the top in bold: "No grading required, just collect the exit tickets for the teacher."
The 50-minute plan, minute by minute
Here is the whole lesson, timed so a substitute never has to improvise:
- 0–5 min, settle and read the board: Students silently answer, "Name one way your phone helped you this week and one way it got in your way."
- 5–15 min, independent reading: Students read the provided passage on the chances and risks of digital media and underline three claims.
- 15–30 min, structured response: Students complete the T-chart, listing benefits on one side and risks on the other, then write a one-paragraph position.
- 30–43 min, talk partners: In pairs, students compare charts and try to change one another's minds using evidence from the text.
- 43–50 min, exit ticket: "Are the benefits of digitalisation worth the risks? Take a side and give one reason." Collected by the sub.
Every step has a paper output, so there is always visible evidence of work and never a dead ten minutes.
Student-facing instructions that run themselves
The secret to a true no-prep day is instructions students can follow without an expert in the room. Keep them concrete and numbered:
- "Work silently until the timer beeps, then you may talk with your partner only."
- "Use full sentences on the exit ticket, one reason is enough."
- "If you finish early, add a second risk and a possible solution."
- "Hand your exit ticket to the substitute on your way out."
Because the topic pairs naturally with control, surveillance, and technology themes, an early-finisher extension can point curious students toward the ideas in Dystopia – Orwell's 1984 and Beyond, asking how a dystopian author might view today's digital media, no prep required, just a discussion prompt on the page.
A backup activity if the room moves fast
Every sub plan needs an overflow option. Leave a single-sheet "silent debate": students write their opinion at the top, pass it, and each classmate adds a written response. It fills any leftover time, needs no tech, and keeps the room calm. If your class is more mature, a short close-reading task drawn from Shakespeare – Analysing a Drama (Macbeth) makes a ready-made backup that keeps the literacy rigor high even on a sub day.
What you will find when you return
Come back to a stack of exit tickets that tells you exactly where the class landed on the debate, a genuine formative snapshot rather than busywork. You will be able to open the next lesson with "Most of you said the risks outweigh the benefits, let's test that," turning a sick day into a real starting point instead of a lost period.
