Expanding and factorising

A series of lessons on expanding and factorising single brackets and expanding and factorising quadratics. The lessons guide students through each step using intelligent practice and exposes them to all the eventualities they are likely to see when presented with these questions. For eg, when expanding single brackets, I have shown all the eventualities of having all positive terms in and outside the brackets, 1 negative, 2 negatives and all negatives. This can help students to develop a deep understanding of how a negative can affect the different parts of the answer and how it affects what is going on inside the brackets when factorising. It also eliminates questions like “there is a negative in front of the x, what do i do now”. This series of lessons fits well with a mastery curriculum as we can ask “what’s the same and what’s different, how will it affect our answer” as we go through the slides. I have added the powerpoint and worksheets to print out for the students.
