In Year 10 Mathematics, students recognise the connection between simple and compound interest. They solve problems involving linear equations and inequalities. They make the connections between algebraic and graphical representations of relations. Students solve surface area and volume problems relating to composite solids. They recognise the relationships between parallel and perpendicular lines. Students apply deductive reasoning to proofs and numerical exercises involving plane shapes. They compare data sets by referring to the shapes of the various data displays. They describe bivariate data where the independent variable is time. Students describe statistical relationships between two continuous variables. They evaluate statistical reports.
Students expand binomial expressions and factorise monic quadratic expressions. They find unknown values after substitution into formulas. They perform the four operations with simple algebraic fractions. Students solve simple quadratic equations and pairs of simultaneous equations. They use triangle and angle properties to prove congruence and similarity. Students use trigonometry to calculate unknown angles in right-angled triangles. Students list outcomes for multi-step chance experiments and assign probabilities for these experiments. They calculate quartiles and inter-quartile ranges.

The following topics provide the framework for learning in Year 9 Mathematics:
ASSESSMENT
Evidence of student achievement will be gathered through tests, investigations and other assessment tasks.
In semester 1, students have a test for each topic. There is a surface area to volume ratio task in Measurement where they investigate why cells that make up living things are so small. In the Probability topic they discover the maths involved in games of chance and how they can increase their chances of winning. In statistics they find correlations between variables of their choosing.
In semester 2 there are also tests for each topic. Additionally, they use their knowledge of Pythagoras and Trigonometry to find the heights of objects around the school and local community. They investigate how interest rates and types of interest can affect their investments and repayments.
Students are assessed against the IB MYP Science assessment criteria:
Criteria A: Knowing and understanding
Criteria B: Investigating patterns
Criteria C: Communicating
Criteria D: Applying mathematics in real-life contexts.
CARE • COMMITMENT • CO-OPERATION • RESPECT
