Pattern sequences and finding the nth term rule

This is a lesson to follow introduction of the nth term rule, which looks at pattern sequences. It is introduced as a contextual problem - a farmer who has to build a fence to separate his sheep from his goats. In this phase, students use mini-whiteboards to give their responses, before moving on to complete a worksheet (slides 18 and 19). Make sure your audio is turned on as sound is embedded in some slides.\n\nPlease rate/comment/favourite as appropriate. All suggestions to improve are welcome. Dave
