'Perception Versus Reality' printed from http://nrich.maths.org/
Why do this problem?
This problem challenges students to think about the way data can be presented to support an argument. There is the opportunity for cross-curricular collaboration as students look at communication and real world issues.
Show the video (and perhaps also the video from the USA linked at the bottom of the problem.
You could pause the video at each stage to allow students to reflect for themselves about their own perception of wealth distribution.
What makes the videos so powerful is the vast difference between people's perception and reality. Ask the class to think of their own areas of interest to find a question they would like to explore, and invite them to prepare presentations similar to the ones in the video. Students will need time to collect data and research their chosen topic.
Particularly powerful presentations could be shared with the rest of the school and the wider community, and perhaps shared through social media.
Picturing the World
invites students to think about data representation of large scale statistics in a slightly less politicised way.
