Sara and Will were sorting some pictures of shapes on cards. "I'll collect the circles," said Sara. "I'll take the red ones," answered Will. Can you see any cards they would both want?
You'll need to work in a group on this problem. Can you use your sticky notes to show the answer to questions such as 'how many boys and girls are there in your group?'.
This activity is based on data in the book 'If the World Were a Village'. How will you represent your chosen data for maximum effect?
Take a look at these data collected by children in 1986 as part of the Domesday Project. What do they tell you? What do you think about the way they are presented?
Have a look at this data from the RSPB 2011 Birdwatch. What can you say about the data?
Class 5 were looking at the first letter of each of their names. They created different charts to show this information. Can you work out which member of the class was away on that day?
When Charlie retires, he's looking forward to the quiet life, whereas Alison wants a busy and exciting retirement. Can you advise them on where they should go?

What happens if this pdf is the arc of a circle?
This was perhaps more challenging than it looked at first. However, many of you worked out how the scoring system worked.
Many of you worked in a very systematic way to solve this challenge.
Lots of evidence of systematic thinking in the solutions we received to this problem.
We received some good solutions explaining why it makes sense to go second when playing with our non-transitive dice.
A random ramble for teachers through some resources that might add a little life to a statistics class.
Can you guess the colours of the 10 marbles in the bag? Can you
develop an effective strategy for reaching 1000 points in the least
number of rounds?
In this short problem, can you deduce the likely location of the odd ones out in six sets of random numbers?
