Further quadratics 1

This is my first lesson with a new year 11 class, revising previously covered material (in year 10).
I have not included worksheets as the ones I am using have come from other sites.

Slides have been animated, which will need checking before running as these can scramble with different versions of powerpoint.

Lesson covers:
Factorising quadratics
Factorising using the difference between two squares
Solving quadratics by factorisation

Please let me know what you think.
