Key Stage 3
At Stretford high School we deliver Realistic Maths Education (RME) and Mastery at Key Stage 3, Years 7 and 8. In RME, mathematics is developed by working with contexts which provide a source for generating mathematical models and hence a deep understanding of where mathematics comes from. Contexts can be taken from the real world, from fiction or from an area of mathematics that students are already familiar with – the important thing is that students are able to imagine and engage with them.
The key features of an RME classroom are:
The scheme is based on 5 maths areas: Number, Algebra, Ratio & Proportion, Probability & Statistics, Geometry & Measures, and Ratio and Proportion delivered in years 7 and 8, consolidated in year 9, laying the foundation for GCSE work in KS4.
