Short answer: put the timer where the whole class can see it and give every activity a start and an end: arrival, solo work, pair talk, a short brain break, tidy-up, practice tests and quiet reading. Pupils stop asking "how long is left?", and you stop watching the clock. Below: seven routines, an example 45-minute lesson and how to set it up in two minutes, free and without logins.
Key takeaways
- Visible time answers "how long is left?" before anyone asks.
- Short rounds (15–20 minutes) fit most lessons better than one long block.
- Brain breaks work best when the timer starts them, not the teacher.
- Tidy-up and transitions get calmer with a 2-minute countdown everyone can see.
- Free Classroom Mode runs in a browser tab, with no accounts and nothing saved about pupils.
Why use a visible timer in class?
A timer on the projector makes time something the whole class shares. Instead of one adult holding the plan in their head, everyone can see what happens now and what comes next.
It helps most in the small moments: getting started, switching from solo work to pairs, or wrapping up before the bell. Those moments add up across a long school week.
Schools in England have been expected to run a school week of at least 32.5 hours since September 2024 (GOV.UK guidance). That is a lot of transitions to manage.
1. Settle in (3 minutes)
Start a short countdown as pupils walk in, with the task already on the board. When the round ends, everyone is seated and the lesson starts on time without a single reminder.
2. Solo work in focus rounds (15–20 minutes)
Set one focus round for independent work. Many classes manage 15–20 minutes well, and you can adjust from 1 to 90 minutes. The ring slowly filling up shows progress without anyone checking a watch.
3. Pair talk (5 minutes, then swap)
Give pairs one round each: partner A explains, partner B listens, then swap when the chime sounds. The chime is off by default, so turn it on in Set up if you want an audible signal.
4. Brain break (2–3 minutes)
Between rounds, Classroom Mode shows a short card: a koala stretch (sitting or standing, both are fine), a breathing pause, a riddle, a doodle or a Finnish word of the day. There are 33 cards per language, in English, German and Finnish, and we will share 12 favourites next week.
Koa's tip: press N to skip to the next break card if one does not fit the moment, and F for full screen on the projector.
5. Tidy-up race (2 minutes)
A two-minute countdown turns tidy-up into a small team challenge. Ask the class to beat the clock together, not each other, so nobody feels rushed or singled out.
6. Practice tests at real length
For mock exams or quizzes, set the round to the real exam length so pupils get used to the pace. A calm, dark board theme keeps the screen easy to look at during long tests.
7. Quiet reading (10–15 minutes)
End with a short reading round. When the last round finishes, Koa puts on a little party hat and the lesson ends on a small, shared win.
When everyone can see the time, nobody has to ask for it.
How to set it up in two minutes
- Open pinkoa.com/class on the classroom computer and connect the projector.
- Type a class name, then open Set up: focus length, break length, number of rounds and a weekly class goal.
- Press Start (or the space bar). Breaks and the next round start by themselves.
- When the class reaches its weekly goal, download the class card and pin it to the wall.
Koa says: nothing about your pupils leaves the classroom computer. No accounts, no logins, and the timer sets no cookies of its own.
