How many dice can I roll at once?

Anywhere from one to six dice. The total updates automatically so the class can check their math against it.

Does the classroom dice roller work on an interactive whiteboard?

Yes. The dice scale to fill the screen, the roll button is a large tap target, and fullscreen mode hides everything except the dice.

What math games can I play with classroom dice?

Plenty by grade band: counting and race-to-20 games in K–2, place value, multiplication and fraction practice in grades 3–5, and probability experiments, integer operations and mean/median/mode work in middle school.

Can I use the dice for a probability experiment?

Yes. Roll two or six dice at a time, tally the sums your class gets, then compare the experimental results with the theoretical probability of each sum.

Yes — no account, no login, and nothing to install. Open the page and roll.

How to use the classroom dice roller

Choose how many dice you need, pick a color that shows up well on your projector, then tap Roll dice (or press Space). The total appears under the dice, so students can check their own addition against the screen. Press F for fullscreen when the whole class needs to see the result.

Classroom games that use dice

Roll-and-write math warmups, place-value practice, addition and multiplication races, story-starter prompts, brain-break movement challenges, and deciding turn order for review games. Pair it with the classroom scoreboard to track team points, or the random student picker to choose who rolls next.

Math games with dice

Dice turn almost any math skill into a quick game. Here are activities sorted by grade band, all playable with the dice on this page and a whiteboard or scrap paper.

Grades K–2: counting and early addition

Roll and count: roll one die, then have students clap, hop, or draw that many objects.
Race to 20: roll two dice, add them, and keep a running total until a team passes 20.
Compare it: roll two dice and ask which is greater, which is less, and by how many.
Make ten: roll one die and name the number that gets you to ten.

Grades 3–5: place value, multiplication, and fractions

Place value builder: roll three or four dice and arrange the digits to make the largest (or smallest) number.
Multiplication showdown: roll two dice and multiply; first correct answer scores a point.
Fraction of the roll: use two dice as numerator and denominator, then simplify or compare fractions.
Rounding rolls: build a three-digit number from three dice and round it to the nearest ten and hundred.

Middle school: probability, integers, and expressions

Probability experiment: roll two dice thirty times, tally the sums, and compare the results with the theoretical probability of each sum.
Integer operations: assign one color of die as negative and add, subtract, or multiply the signed values.
Expression builder: roll for the coefficient and constant, then evaluate or solve the resulting equation.
Mean, median, mode: roll six dice and find all three measures of center from one screen.

For probability work, roll six dice at once to gather data faster, and use the classroom timer to keep each round short.
