Key Stage 3

At Stretford high School we deliver Mastery at Key Stage 3 (White Rose). Maths mastery is a teaching and learning approach that aims for pupils to develop deep understanding of maths rather than being able to memorise key procedures or resort to rote learning. Mastery of a mathematical concept means a child can use their knowledge of the concept to solve unfamiliar word problems, and undertake complex reasoning, using the appropriate mathematical vocabulary.

The underpinning principles of Mastery are:

Mathematics teaching for mastery assumes everyone can learn and enjoy mathematics.
Mathematical learning behaviours are developed such that pupils focus and engage fully as learners who reason and seek to make connections.
Teachers continually develop their specialist knowledge for teaching mathematics, working collaboratively to refine and improve their teaching.
Curriculum design ensures a coherent and detailed sequence of essential content to support sustained progression over time.

The scheme is based on 5 maths areas: Number, Algebra, Ratio & Proportion, Probability & Statistics, Geometry & Measures, and Ratio and Proportion delivered in years 7 to 9, laying the foundation for GCSE work in KS4.
