Mathematics is a core curriculum subject. Students should build on Key Stage 2 work and make connections across mathematical ideas to develop fluency, mathematical reasoning and competence in solving increasingly sophisticated problems.

Students at Heathside study Mathematics for four periods of 50 minutes per week in Key Stage 3. Students are placed in ability groups at the start of Year 7 based on data from primary schools and our own assessments. Student ability is reviewed using data from chapter tests, half-term assessments, and end-of-year assessments.

**Year 7**

Students study the following topics:

- Numbers (directed numbers, decimals, fractions, percentages, ratio, BIDMAS, and estimates).
- Algebra (sequences, expressions, formulae, equations, and graphs).
- Geometry and Measures (perimeters, areas, volumes, angles, constructions, and transformations).
- Statistics (averages, probability, analysis, and representing data).

**Year 8**

Students study the following topics:

- Numbers (directed numbers, decimals, fractions, percentages, ratio, HCF, LCM, and powers).
- Algebra (sequences, expressions, formulae, equations, indices, and graphs).
- Geometry and Measurements (angles, constructions and loci, circles, transformations, scale drawings, conversion of units of area and volume, surface area, and volume of prisms).
- Statistics (probability, interpreting, and representing data).

**Year 9**

Students study the following topics:

- Numbers (HCF, LCM, BIDMAS, indices, fractions, decimals, ratio and proportion).
- Algebra (expressions, factorisation, changing the subject of a formula, graphs, sequences, and indices).
- Geometry and Measurements (angles, polygons, imperial and metric units, compound measures, area, volume, transformations, loci, Pythagorasâ€™ theorem, similar shapes, and congruency).
- Statistics (statistical representation and measures).

**United Kingdom Mathematics Trust (UKMT)**

Students with a natural ability in Mathematics are entered annually in UKMT Maths Challenges. Years 7 and 8 are entered for the UKMT Junior Challenge, while Year 9 are entered for Intermediate Challenge. The challenges involve answering 25 multiple choice questions in one-hour exam conditions and without the use of a calculator.
