From http://www.shoeguide.org/Shoe_Sizinghttp://www.shoeguide.org/Shoe_Sizing How long, in centimetres, do you think a size 21 shoe will be? Why?

Can you imagine the size of the person who could fit into them?

The tallest man ever to have lived is Robert Wadlow (1918 – 1940 ), pictured here with his father. He was 2.72 metres (8 ft 11 inches) tall and wore US size 25 shoes (pictured above next to US size 12). How tall might the wearer of the size 21 trainers be? What else can you predict about him?

It’s in the News! Big foot Teacher Notes

Big foot Introduction: A pair of size 21 trainers has been found at a petrol station in Derbyshire! Police are hunting high and low (though maybe not too low!) for the owner of the enormous Nike basketball boots. Denise Bostock, who works in the lost property office for the police said, “You just can’t imagine the size of the person who could fit into them.” It’s this statement that this resource explores, using the context of the shoes to make predictions – firstly, in a number sequence, and then using survey data. Content objectives: This context provides the opportunity for teachers and students to explore a number of objectives. Some that may be addressed are: communicate own findings effectively, orally and in writing, and discuss and compare approaches and results with others generate terms of a linear sequence using term-to-term and position-to-term rules, on paper and using a spreadsheet or graphics calculator plan how to collect the data; construct frequency tables with equal class intervals for gathering continuous data and two-way tables for recording discrete data write about and discuss the results of a statistical enquiry using ICT as appropriate; justify the methods used. Process objectives: These will depend on the amount of freedom you allow your class with the activity. It might be worth considering how you’re going to deliver the activity and highlighting the processes that this will allow on the diagram below:
