Free Dice Roller for Teachers

Roll configurable dice — choose sides and count.

How to use this in your class

  • •Use two six-sided dice for quick addition practice — students call out the sum before the dice stop bouncing.
  • •Set up a 20-sided die for RPG-style classroom quests where students roll to determine challenge difficulty.
  • •Roll multiple dice at once for probability lessons — ask students to predict the most common totals.
  • •Use a single die to assign page numbers, textbook problems, or review questions at random.
  • •Let students take turns pressing Roll on the projected screen to keep them physically engaged.

Why use a dice roller for classroom?

Physical dice are fun but impractical for a whole class. They roll off desks, get lost, and only the students nearby can see the result. A dice roller for classroom use puts the roll on the projector so every student sees the outcome at the same time. It's also configurable — need a 12-sided die or five dice at once? Done in one click, no rummaging through a supply closet.

How this dice roller works

Choose the number of dice (1–10) and the number of sides per die (4, 6, 8, 10, 12, or 20). Press Roll and each die animates before landing on a random result. The total is displayed clearly beneath the dice. You can roll again instantly or change the configuration for a different activity.

Digital dice vs. physical dice

Physical dice have their charm, but they're hard to manage in a classroom of 25+ students. A digital dice roller is visible on the big screen, impossible to lose, and offers die types (d8, d10, d12, d20) that most classrooms don't stock. It's also faster for repeated rolls during math games or probability experiments.

Tips for effective use

  • For math warm-ups, roll two dice and ask students to multiply the results — change the operation each day.
  • Use a single die to randomly select question numbers from a worksheet for whole-class review.
  • In probability units, have students predict the outcome distribution before rolling 50 times and comparing.
  • Add gamification by letting students roll for bonus points during review sessions.
