Each one on its own page
Dice roller
One die or six, from d4 to d100, drawn as the solid it is.
Coin flip
Heads or tails, with a running tally of the flips so far.
Random number
A number out of any range, with no repeats if you want.
Random letter
A letter of the alphabet — all of them, or only vowels.
Good to know
Are the draws really random?
Every result comes from your browser’s cryptographic random source, and it is drawn before anything moves on screen. The die tumbling and the coin turning are animations played towards a result that has already been decided, so they cannot nudge it.
Why one page per die and per range?
Because that is how they are asked for. A page for a twenty-sided die can say what is true of twenty faces — the odds, the average roll, how many rolls it takes to see them all — and a page for 1 to 100 can count the primes in it. Both are computed from the numbers, not written out.
Does anything get sent anywhere?
No. The pickers need nothing from you: there is no list, no account and no upload. Your last result and the tally of flips are kept in this browser so a reload in front of the class changes nothing.
The rest of the kit
Name wheel
Spin to pick a pupil. Nobody is picked twice until everyone has had a turn.
Random groups
Split the class into even groups in one click, by number of groups or by size.
Classroom timer
A countdown the back row can read, with a bar that turns amber, then red.
Stopwatch
Start, lap, stop. Laps with splits, fastest and slowest marked.
Focus timer
Work and break rounds that run by themselves, 25 and 5 or your own.
