Maths Key Stage 3 – Theta (Intermediate)


In maths at Stretford High school students follow a 5 year tiered scheme of work based on 5 maths areas: Number, Algebra, Probability & Statistics, Geometry and Measures, and Ratio and Proportion which starts in KS3 and lays the foundation for GCSE work in year 9 and throughout KS4. KS3 pupils follow the Pi, Theta or Delta programme using a variety of teaching methods and applying the Mathematics to real life situations. The programme includes problem solving mathematics including financial planning. Students are assessed at the end of each unit and half term, they are notified of their strengths and areas for development so they are clear of what they have done well and how to improve for next time.

Students study the Mathematics National Curriculum and through this we aim to develop our students as follows:

  • a positive attitude towards mathematics, as well as competence and confidence in mathematical knowledge, concepts and skills;
  • an ability to solve problems, to reason, to think logically and to work systematically and logically;
  • the skills to use their own initiative and an ability to work both independently and in co-operation with others;
  • an ability to communicate through mathematics and to use and apply mathematics across the curriculum and in real life.
