This lesson develops the concept of ‘Greatest Common Factor’ (GCF) and ‘Least Common Multiple’ (LCM). The central theme is to separate out the two concepts.

There is an introductory ‘guess my numbers’ activity. The GCF and LCM of a pair of numbers is given and students must work out what the numbers are,...

This resource from Ofsted is a full report and summary of the findings from a visit, in September 2009, made by two of Her Majesty's Inspectors to educational establishments in Finland.

In this predict-observe-explain activity, students explore different ways of extinguishing a flame with some surprising results. The lesson is introduced with the video of engineer Yusuf Muhammad. Yusuf is developing a revolutionary new household fire-safety device, incorporating the techniques of professional...

This video demonstrates how compressing a gas increases its temperature. A small piece of cotton wool is placed into the bottom of a narrow plastic tube. When the air is rapidly compressed by a piston, the air temperature increases and the cotton ignites. The 'fire piston' can be used to illustrates the transfer of...
