In #MathsToday Yr 1 #AlevelMaths proved the quadratic formula using an underground maths card sort, did some explorative work on key features of quadratic functions using factorised form and completing the square and then completed DrAustin finding quadratic equations from their graphs.

Totally agree as solid base, but care should be taken to avoid forcing students to think there is a 'right' way to begin. Apologies for lack of clarity in 2nd example. (1/2)x + 2/3 = 1/6 Multiply the whole equation by 6 as an example of a good first move. Admittedly unlikely to feature at y7.

I agree it's logical, but still feels like it would create barriers to fluency/flexibility to me. What about something like 123x + 246 = 369? Or 1/2x + 2/3 = 1/6?

I’m pretty sure my kid’s school got @draustinmaths.com to design their packed lunch ideas.

Maybe. You might prefer Imperial wherever you are in the UK. I still think two is a bit low for such impressive results. I’m thinking maybe they have been well drilled to pass A levels but less well prepared for entrance tests and/or interviews.
