Factorising trinomials

Just in case I forget, Dan’s activity on factoring trinomials by creating a headache – it’s a good one that I’ve used a couple of times and seems to spark enough interest.

Jon Orr’s introduction of factoring is a bit different, but may still have some helpful content?

Also wanted to keep a digital record of the resource I’ve used a number of times with the flowchart for factorising in general – a helpful tool (factorising).
