Shut the Box

Stage: 1 Challenge Level: Challenge Level:1

An old game but lots of arithmetic!

problem icon

Sorting Numbers

Stage: 1 Challenge Level: Challenge Level:1

Use the interactivity to sort these numbers into sets. Can you give each set a name?

problem icon

Birds in the Garden

Stage: 1 and 2 Challenge Level: Challenge Level:1

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?

problem icon

Three Spinners

Stage: 2 Challenge Level: Challenge Level:1

These red, yellow and blue spinners were each spun 45 times in total. Can you work out which numbers are on each spinner?

problem icon

How Random!

Stage: 2 Challenge Level: Challenge Level:2 Challenge Level:2

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?

problem icon

Can't Find a Coin?

Stage: 3 Challenge Level: Challenge Level:2 Challenge Level:2

Can you generate a set of random results? Can you fool the random simulator?

problem icon

Which Spinners?

Stage: 3 and 4 Challenge Level: Challenge Level:1

Can you work out which spinners were used to generate the frequency charts?

problem icon

Distribution Differences

Stage: 4 Challenge Level: Challenge Level:2 Challenge Level:2

How could you compare different situation where something random happens ? What sort of things might be the same ? What might be different ?

problem icon

Introducing Distributions

Stage: 4 Challenge Level: Challenge Level:2 Challenge Level:2

When five dice are rolled together which do you expect to see more often, no sixes or all sixes ?

problem icon

Coin Lines

Stage: 4 Challenge Level: Challenge Level:2 Challenge Level:2
