The Penny Mile

Mainly aimed at Functional Skills as a revision task. Coverage includes:
To be able to convert between metric units
To be able to use simple formula to convert between metric and imperial units
To be able to work out the volume of an object
To be able to calculate the weight of an object
To be able to work out the mean average of a set of data
To be able to solve problems involving time
Exam style task based on recent events in my life, so very Functional. This could also be adapted to allow the students to do their own "How many in a minute" part, but just need the pennies. This task took most of my students a lesson. Please feel free to let me know if there is anything that could be improved.
