An online dice roller for class games and math

This online dice roller replaces the handful of dice that always roll off the table. Roll up to six dice at once, see the total instantly, and put them on the projector so everyone sees the same result. Six-sided dice show real pips, which helps younger students practice subitizing, while other dice show the number.

Switch between d4, d6, d8, d10, d12 and d20 dice for different games and math lessons. A pair of six-sided dice is perfect for addition facts, two d10s make two-digit numbers, and a d20 adds suspense to review games.

Every face has the same chance on every roll. Because nothing physical is involved, there are no lost dice, no noise and no arguments about a die that landed on its edge.

Classroom ideas for dice

  • Roll and add

    Roll two dice and have students write the addition sentence. Use three dice for a challenge.

    Roll two dice 50 times and graph the totals. Why does 7 come up most?

  • Review game points

    Answer a question correctly, then roll to see how many points the team earns.

  • Story dice

    Roll to choose a character, a setting and a problem from three numbered lists.

  • Exercise breaks

    Roll a die for the number of jumping jacks or stretches in a brain break.
