Peer marking tip for Year 11: don't give out the mark scheme. The moment it appears, the answer is definitive and the conversation stops. It's the argument about whether an answer is valid that builds reasoning. More: mr-mathematics.com/grade-7-gcse...

Quadratic and Linear Simultaneous Equations
Curriculum Hub → Maths Lessons → Quadratic and Linear Simultaneous Equations Ready-to-teach lesson. Includes editable slides, a video tutorial and a printable worksheet. Saves 2+ hours of planning. Most students can substitute one equation into another when told to. Far fewer can explain why substitution works here when elimination doesn't, or spot which variable to substitute for when the quadratic is a circle rather than a parabola.
