## Why do we study Mathematics?

Mathematics is one of our core subjects, enabling students to develop the skills needed to become the problem-solvers of the future. There are thousands of different jobs that require some knowledge of Mathematics and many practical applications in day-to-day life. You may not want to be an engineer and design the next Tasman Bridge but students will certainly need to cook and adapt recipes or possibly secure a loan to buy their first car.

At Rose Bay we have a strong focus on developing multiplicative thinking in Year 7 and 8 to enable students to access all areas of the Australian Curriculum in Mathematics. We offer many opportunities for students to extend their skills through Maths by Inquiry in Year 8, Accelerated Mathematics in Year 9 and General Mathematics – Foundation and Mathematical Methods – Foundation in Year 10.

## Middle School Program of Study

## Year 7

**Topics and Units of Work Studied**

The duration of a unit of work is usually between four to five weeks. Topics covered in Year 7 include:

**Measurement**– Perimeter, area and volume**Geometry 1**– Angles and parallel lines**Algebra**– Substitution, simplifying expressions and solving simple linear equations**Fractions, decimals and percentages****Data**– Graphical representations of data, calculation of mean, median and mode**Geometry 2**– Triangles and quadrilaterals, the Cartesian plane, transformations.**Probability**– chance, equally likely events

We assess students on their multiplicative thinking at the beginning of Year 7 enabling teaching and learning experiences to be tailored to meet students’ needs. Development of numeracy skills are taught throughout the year and are integrated within each of the units of work.
