This powerpoint was made for a mixed ability Year 5/6 class, but would work well for Year 7 & 8 too. To improve accessibilty I have included some clue cards which I hope will be useful.
Finding the nth term suitable for low ability KS3/4. Resources include a PowerPoint lesson, blank grids to support less able students, bronze worksheet (ascending sequences), silver worksheet (descending sequences) and answers! Went down well as an observed lesson - let me know what you think!
