Interactive Dice
Classroom · Year 1–Year 6
Roll up to six dice. Hold the ones you keep and roll the rest.
About the dice
Tap anywhere to roll. The total is at the top, big enough to read from the back, and it updates as you go.
Tap a die to hold it and the next roll leaves it alone. That is the thing a real pair of dice cannot do on a whiteboard, and it turns the tool into a proper probability activity: hold a six, roll for the second one, and talk about what you need.
Choose one to six dice, and six, ten or twelve sides. Six-sided dice show the usual spot patterns, because recognising five without counting it is half the reason to use dice at all. Above six the faces show a numeral instead.
Because tapping the mat rolls, it still works in fullscreen with the controls put away, which is when a class is most likely to be using it.
How to use it on your whiteboard
- 1Tap anywhere on the mat to roll.
- 2Tap a die to hold it. Held dice keep their value when you roll again.
- 3Use the plus and minus buttons to change how many dice you have.
- 4Switch between six, ten and twelve sides.
- 5Undo steps back through the rolls, so you can go back to the one before.
Questions
- Can I hold a die and roll the others?
- Yes. Tap a die to hold it and it keeps its number on the next roll. Release all puts them back in play.
- How many dice can I roll?
- Up to six. They resize so they stay readable, and six go in two rows of three rather than one long row.
- Are the dice fair?
- Yes, each face is equally likely on every roll, and held dice are simply not rolled.
