Mathematics is a progressive subject - in order to master a given skill, it is often necessary to have mastered other skills already.  With this in mind we have organised the secondary maths curriculum into 'stages' and we name them according to the colours of the rainbow.  Pupil's work on a given stage for a year and then move on to the next stage in order to build their skill level across a broad range of topics.  We also work through four phases each year before revising them all at the end.  

The phases are: 

Each pahase concludes with a test.  There is not a set length of time allocated to each phase as, for example in the purple stage, there is a great deal of algebra and not so much number, whereas in the orange stage there is much more number and not so much algebra to cover.  They last 'roughly' 6-8 weeks each.
