Virtual Dice Roller

How teachers use virtual dice

Real dice are brilliant until they are on the floor, in a pocket, or missing the six. A projected die does the same job for the whole class at once, and nobody has to squint at a table to see what came up.

In Year 3 maths especially, dice are the fastest way to generate practice that does not feel like a worksheet. Roll two dice for a two-digit number, roll again for another, and the class has an addition to do that nobody wrote out in advance.

• Generating random numbers for column addition and subtraction
• Times tables practice — roll two dice and multiply
• Place value: roll three dice to build a three-digit number, then order or compare
• Probability work in upper key stage 2, where lots of rolls are needed quickly
• Board games and phonics games with no physical dice in the room
• Choosing at random between six options without a wheel

Sides, totals and how many dice

Six-sided dice cover most primary maths, but you can change the number of sides — ten-sided dice are useful for place value and decimals, and larger dice make probability work more interesting. The total is shown alongside the individual dice, so you can use it either way.

Rolling more than one die at a time is what makes it useful for arithmetic: two dice for addition, three for a three-digit number, six when the whole table needs a number each.

Making it a talk activity, not a click activity

The dice generate the numbers; the talk is the lesson. Before you roll, agree what the class does with the result: "when I roll, tell your partner the answer before I ask anyone." That way every child does the thinking, not just the one who gets asked.

For EAL learners, keep the sentence the same every time — "I rolled a four and a three, so the answer is seven" — so the language is a scaffold they can reuse rather than a new hurdle on every roll.
