Random student picker for the classroom

Cold calling, choosing who goes to the board, forming lab groups, setting presentation order: these small decisions eat up class time and can feel unfair to students. This random student picker handles them in seconds on the projector, so the class can see the pick is random.

Everything you reach for during a lesson is on one screen:

• Who's next? A big name picker with a short shuffle animation.
• Groups. Split the class by group size or number of groups.
• Order and pairs. Presentation order, turn order or partner pairs.
• Timer. Huge digits, a color bar that turns amber and red, and a chime at zero.
• Dice and coin. For games, review activities and quick decisions.

It all runs in your browser. Your roster is never uploaded.

A plain random picker can call the same student twice in a row while someone else waits for weeks. Fair rotation fixes that: once a student is picked, they sit out until every student who's present has had a turn, and then a new round starts.

The round is saved per class, so next period you pick up where you left off. Turn it off if you want every pick to be fully random, repeats included.

Mark absent students with one tap. They won't be picked or put into groups, and "Everyone's here" clears the list at the end of the day.

Full screen mode (press F) scales everything up so it's readable from the back row. Choose a dark or light background depending on your room and projector.

Key	What it does
Space or Enter	pick the next student
1–6	switch view (picker, groups, order, timer, dice, coin)
F	full screen on or off
Esc	leave full screen

A wireless presentation clicker that sends Space or Enter works too, so you can pick from anywhere in the room. It also works on interactive whiteboards and Chromebooks.

Make a roster for each class or period and switch between them from the menu at the top. Paste names straight from your grade book or a spreadsheet, one per line. Duplicate names are counted once, so add a last initial if two students share a first name.

Rosters, absences and the fair-rotation progress are saved only in this browser. On a different computer you'll need to paste the roster again, and clearing your browser data removes them. Because nothing goes to a server, there's no student data to manage or delete on our side.

The classroom timer shows the time left in huge digits, with a bar that shifts from green to amber to red so students in the back row can see how much time is left. One-tap presets cover 30 seconds and 1, 2, 3, 5, 10, 15 and 20 minutes, or type your own. A chime sounds at zero when sound is on; switch it off for quiet work.

Use it for group work so every group gets the same time, for presentations, for a two-minute brain dump, or for clean-up countdowns. The dice roll one to four standard dice and show the total, handy for probability lessons and review games. The coin flip keeps a running count of heads and tails, which makes a quick demo of how results even out over many flips. Every tool sits on the same screen, so you switch with the buttons or the 1–6 keys instead of opening new tabs.

There are also stand-alone versions built for the projector: the classroom timer shows time left as a traffic light or a shrinking ring, the classroom noise meter listens to the room's volume, and the classroom seating chart builds a seating plan from the same class lists.

• Warm-ups and review: call on two or three students at the start of class.
• Group work: let the picker make groups of four so students work with new classmates.
• Presentations: shuffle the order ahead of time, copy it, and give everyone the same time on the timer.
• Think-pair-share: pairs mode gives everyone a partner; with an odd number, one group of three forms.
• Games and decisions: who goes first, which question to tackle next: roll the dice or flip a coin.

Picks use your browser's cryptographic random number generator, so no student is more likely to be chosen than another.
