Dice for School Maths Lab

Quick Answer: Dice for School Maths Lab are numbered cubes that students roll to generate random outcomes for probability experiments and number games. Using dice for probability, pupils compare what they expect from equally likely outcomes with what actually happens when they roll many times.

Chance You Can Hold

A fair die is the simplest random generator a classroom can have. The title does not specify the dice type, so this page assumes the standard six-faced cube with faces numbered one to six, where each score has a theoretical probability of 1/6. Students predict how often a six should appear in sixty rolls, then roll and tally. The results never match the prediction exactly, and discussing why leads to the difference between theoretical and experimental probability.

Pooling results is where dice lessons become convincing. One pair rolls sixty times and gets an uneven spread; the whole class together may roll well over a thousand times, and the relative frequency of each score moves closer to 1/6. This is the law of large numbers in a form pupils can see on the board.

Two dice open a richer problem. The sums range from 2 to 12, but they are not equally likely: a sum of 7 can be made in six of the thirty-six possible combinations, while 2 and 12 can each be made in only one. Students draw the 6 × 6 grid of outcomes to explain why 7 turns up most often.

Specifications

Applications

• Comparing experimental results with the theoretical probability of 1/6
• Pooling class results to show relative frequency settling as trials increase
• Listing the 36 outcomes for two dice and explaining why 7 is the most common sum
• Mental arithmetic games: add, subtract or multiply the scores on two dice
• Place-value games in which rolled digits are arranged to make the largest number

Care & Handling

• Roll the dice into a tray or box lid to keep them on the table and reduce noise.
• Count the dice back after each lesson; small cubes are easily lost.
• Store dice out of reach of toddlers, for whom any small cube is a choking hazard.

Why Choose LabEquip

Maths departments usually order dice in class quantities, so each pair of students can run its own trials and add to a pooled class result. LabEquip lists them in the Mathematics School Lab Products range, where the Data Collection Board gives a quick way to graph the outcomes; ask about quantities through the contact page.

Frequently Asked Questions

What is the probability of rolling a six with one die?

On a fair six-faced die each face is equally likely, so the probability of a six, or of any single score, is 1 out of 6. That does not mean one six in every six rolls; it describes the long-run proportion.

Why does a sum of 7 come up most often with two dice?

There are 36 equally likely ways two dice can land. Six of them make 7: 1 and 6, 2 and 5, 3 and 4, and the same pairs reversed. Sums of 2 and 12 can each be made in only one way.

Why don’t 60 rolls give exactly ten of each number?

Each roll is random, so short runs of results are uneven. As the number of rolls grows, the proportion of each score tends to get closer to 1/6, which is why pooling the whole class’s results works better than one pair’s.

How can dice support arithmetic practice?

Students roll two or three dice and add, subtract or multiply the scores against the clock. Rolling digits and arranging them to make the largest or smallest possible number also practises place value.

How can students test whether a die is fair?

Roll it many times, tally each score and compare the frequencies. Small differences are expected by chance, but one score appearing far more or less often than the others over hundreds of rolls suggests the die may be biased.

What type of dice does the listing include?

The title names dice without stating the number of faces, so confirm the type, quantity and colours when you enquire. The activities on this page assume the standard six-faced cube.
