This is a whole lesson looking at expanding quadratics, or 2 parenthesis.
It has a neat multiplication starter linking the grid method learnt into expanding, but also looks briefly at the foil method, i.e. arrows. It has 6 different examples of questions, and then has differentiated questions within the PowerPoint, with answers and plenary. It also includes full learning objectives and key words.
I have found this PPT a very good way of getting all students to understand and be able to expand two parenthesis. It also includes a help sheet that I give out, especially for the lower ability students, which is an excellent way of differentiating.
This is normally the second lesson I would teach on expanding / factorizing.
1. Expanding 1 Parenthesis
