Is it weird I am excited to teach my Year 9s next week?

I wanted to extend solving quadratics by factorising but with more algebraic manipulation and problem solving. Too often kids have simple and boring quadratics to solve.

Comments are welcome.

Fun with quadratic sequences. There is more to quadratic sequences than just finding the nth term.

Check out this lesson for higher GCSE students on problem solving with the quadratic nth term.
