Hi! I have an observation on Tuesday with top set year 8's (level 7) on finding the nth term of a quadratic sequence. I have to admit that when I taught this last year I fell into the trap of teaching students the process rather than letting them discover the process and links themselves (and this wouldn't go down well with my observer). Has anyone got any ideas on how I could structure this lesson to encourage the students to start discovering this themselves? They are a bright class and good at team work (if lacking in confidence at times!). I was thinking of giving them some linear nth term to start (which they are all confident with) and throwing in a 'one that doesnt work' (quadratic) Thank you in advance!
