This activity challenges you to make collections of shapes. Can you
give your collection a name?
An old game but lots of arithmetic!
Use the interactivity to sort these numbers into sets. Can you give
each set a name?
This activity asks you to collect information about the birds you
see in the garden. Are there patterns in the data or do the birds
seem to visit randomly?
These red, yellow and blue spinners were each spun 45 times in
total. Can you work out which numbers are on each spinner?
Explore this interactivity and see if you can work out what it
does. Could you use it to estimate the area of a shape?
Which of these ideas about randomness are actually correct?
Can you generate a set of random results? Can you fool the random
Can you work out which spinners were used to generate the frequency charts?
How could you compare different situation where something random
happens ? What sort of things might be the same ? What might be
When five dice are rolled together which do you expect to see more
often, no sixes or all sixes ?
If a coin rolls and lands on a set of concentric circles what is
the chance that the coin touches a line ?
Estimate areas using random grids
Use your skill and judgement to match the sets of random data.
What is a random pattern?
By exploring the concept of scale invariance, find the probability
that a random piece of real data begins with a 1.
Can you build a distribution with the maximum theoretical spread?
Many of you explained each step of your solution to this problem
Those big numbers didn't seem to frighten you away. Take a look at
how some of the problems were tackled.
This was a popular problem. Many of you managed to make sense of
all that jumbled up information.
Matthew offers a good explanation of what appears to be happening
In the time before the mathematical idea of randomness was discovered, people thought that everything that happened was part of the will of supernatural beings. So have things changed?
This interactivity invites you to make conjectures and explore
probabilities of outcomes related to two independent events.
Four numbers on an intersection that need to be placed in the
surrounding cells. That is all you need to know to solve this
This tool allows you to create custom-specified random numbers,
such as the total on three dice.
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.
In Classical times the Pythagorean philosophers believed that all
things were made up from a specific number of tiny indivisible
particles called ‘monads’. Each object contained a
different number of particles, and so they believed that
‘everything was number’.
