# Mathematics

###### Year 9

##### Subject Information

Mathematics is a compulsory full year subject in Year 9.

##### Subject Description

This course is a general course which follows the Australian Curriculum guidelines. Students who have demonstrated a need for extra support may be grouped together to work on modified material with a pathway to Essential Mathematics. Students who demonstrate both high level problem solving skills and a passion for Mathematics will be extended with advanced material.

Students solve problems involving simple interest, apply index laws to numbers, express numbers in scientific notation, and explain the use of relative frequencies to estimate probabilities. Students calculate areas of shapes and the volume and surface area of prisms. Using Pythagoras’ Theorem and trigonometry students find unknown sides and angles of right-angled triangles and apply ratio and scale factors to similar figures. They are able to simplify a range of algebraic expressions,solve equations and describe the relationship between graphs and equations. Students sketch linear and non-linear graphs and determine the gradient and midpoint of a line segment.

All Year 9 students will have access to HOTmaths, an interactive online learning environment to support their learning.

Topics include:

Financial Mathematics

Pythagoras’ Theorem

Statistics and Probability

Algebra – Expanding and Factorising

Geometric Reasoning

Trigonometry

Introduction to non-linear relationships

Measurement

##### Course Fees

Nil.

##### Additional Costs
