A random number generator for 1 to 3. Press the button and the reels land on 1, 2 or 3, which is handy for choosing between three groups, three jobs or three games.

How to use it

  1. The range is already set from 1 to 3. Press Hold to roll or the Space bar, and let go to land on a number.
  2. The same number can come up again. Tick No repeats to use each number once.
  3. For another range, type the lowest and highest numbers in the boxes, or open the full random number generator for odd, even, multiples and more.

Ideas for class

  • Label three table groups 1, 2 and 3 and draw a number to decide which group shares its answer first.
  • Run a three-way choice for the last ten minutes of the day: story, drawing or a quiet game, each with a number.
  • Give three children the jobs of reader, writer and checker, then draw numbers to see who does which job today.
  • Play a guessing game in which each child holds up one, two or three fingers, then draw a number and see who guessed it.

Questions

Can I use it to pick between three options?

Yes. Give each option a number from 1 to 3, write them on the board, and press the button. Every option has the same chance, so nobody can say the choice was unfair.

What if I want each number to come up once before any repeats?

Tick No repeats. Then 1, 2 and 3 each come up once, in a random order, and the tool tells you when all three have been used. Reset puts them back.

Does it work on a tablet or an interactive board?

Yes. Tap or hold the big button, or press the Space bar on a keyboard. The numbers are large enough to read from the back of a classroom, and nothing is sent anywhere.
