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?

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.
