This maths masterclass explores practical ways of looking at continuous data averages using the very practical example of what size gloves a glove company should make. To gets to grips with continuous data such as hand sizes rather than discreet data such as the number of sweets in a jar, award-winning teacher Jonny Heeley and a group of 20 13-year-old students demonstrate the use and usefulness of calls intervals and cumulative frequency graphs. The objective is to enthuse teachers and teach students using situations that are easy and practical to set up in a school classroom. Jonny Heeley's talent lies in empowering the students and encouraging them to express their thoughts and ideas out loud as they work together towards an understanding of the maths.
