# Plan 50 – where my maths GCSE class are going to get their next 50 marks Plan 50 is the name I’m giving to a drive for each of my year 11 pupils to gain an additional 50 marks in their final mock exam in March compared to one they’ve just done in November.

The list below is all the things I’m going to cover over the next 50 lessons. The idea is for students to gain 1 extra exam mark per lesson. This list is more for me and for them but I thought I’d share it more widely in case it helps others.

As it stands, they’re grouped by general topic but they’re in no particular order. As I teach them, I’ll be bundling some together and pulling out the links between them, e.g. a few fractions lessons will take in the basic operations, solving algebraic fractions, pie charts, area of segments and best buy questions. When it comes to grouped frequency tables we’ll look at calculating the mean as well as drawing c.f. curves and histograms. With negative numbers, we’ll cover negative number operations, simplifying expressions, expanding brackets involving a negative, negative powers, vectors in the opposite direction and negative scale factors.

You’ll notice there are more than 50 items in the list… we can’t be too sure where those marks are going to come from!
