A maths-based Football World Cup simulation for teachers and students to use.
Charlie thinks that a six comes up less often than the other
numbers on the dice. Have a look at the results of the test his
class did to see if he was right.
What can you say about the child who will be first on the playground tomorrow morning at breaktime in your school?
Try out the lottery that is played in a far-away land. What is the
chance of winning?
What statements can you make about the car that passes the school gates at 11am on Monday? How will you come up with statements and test your ideas?
Kaia is sure that her father has worn a particular tie twice a week
in at least five of the last ten weeks, but her father disagrees.
Who do you think is right?
Roll two red dice and a green dice. Add the two numbers on the red dice and take away the number on the green. What are all the different possibilities that could come up?
Engage in a little mathematical detective work to see if you can spot the fakes.
Move your counters through this snake of cards and see how far you
can go. Are you surprised by where you end up?
Can you generate a set of random results? Can you fool the random
Which of these ideas about randomness are actually correct?
Imagine a room full of people who keep flipping coins until they
get a tail. Will anyone get six heads in a row?
Use this animation to experiment with lotteries. Choose how many
balls to match, how many are in the carousel, and how many draws to
make at once.
Can you work out which spinners were used to generate the frequency charts?
Simple models which help us to investigate how epidemics grow and die out.
A simple spinner that is equally likely to land on Red or Black. Useful if tossing a coin, dropping it, and rummaging about on the floor have lost their appeal. Needs a modern browser; if IE then at. . . .
You'll need to work in a group for this problem. The idea is to
decide, as a group, whether you agree or disagree with each
Six balls of various colours are randomly shaken into a trianglular
arrangement. What is the probability of having at least one red in
In this game you throw two dice and find their total, then move the appropriate counter to the right. Which counter reaches the purple box first? Is this what you would expect?
7 balls are shaken in a container. You win if the two blue balls
touch. What is the probability of winning?
Is this a fair game? How many ways are there of creating a fair
game by adding odd and even numbers?
Can you beat Piggy in this simple dice game? Can you figure out
Piggy's strategy, and is there a better one?
All you need for this game is a pack of cards. While you play the
game, think about strategies that will increase your chances of
This is a game for two players. You will need some small-square
grid paper, a die and two felt-tip pens or highlighters. Players
take turns to roll the die, then move that number of squares in. . . .
Have a go at this game which involves throwing two dice and adding
their totals. Where should you place your counters to be more
likely to win?
Use the interactivity or play this dice game yourself. How could
you make it fair?
This interactivity invites you to make conjectures and explore
probabilities of outcomes related to two independent events.
Identical discs are flipped in the air. You win if all of the faces
show the same colour. Can you calculate the probability of winning
with n discs?
Think that a coin toss is 50-50 heads or tails? Read on to appreciate the ever-changing and random nature of the world in which we live.
This article, for students and teachers, is mainly about
probability, the mathematical way of looking at random chance and
is a shorter version of Taking Chances Extended.
