Factorising Quadratics

I am looking at factorising with year 9 after half term and I have been thinking about starting the lesson with the following task. I know they have looked at rectangles regularly at KS2 and KS3 and our next unit after the current one is on 2D shapes. I thought this activity would give them a good starting point to start factorising quadratic by inspection.

  1. Brilliant…I love this! I’ve used 2D shapes to talk about collecting like terms when doing perimeter and area but makes perfect sense to introduce factorising quadratics like this!
