In Year 8 Mathematics, students solve everyday problems involving rates, ratios and percentages. They describe index laws and apply them to whole numbers. They describe rational and irrational numbers. Students solve problems involving profit and loss. They make connections between expanding and factorising algebraic expressions. Students solve problems relating to the volume of prisms. They make sense of time duration in real applications. They identify conditions for the congruence of triangles and deduce the properties of quadrilaterals. Students model authentic situations with two-way tables and Venn diagrams. They choose appropriate language to describe events and experiments. They explain issues related to the collection of data and the effect of outliers on means and medians in that data.
Students use efficient mental and written strategies to carry out the four operations with integers. They simplify a variety of algebraic expressions. They solve linear equations and graph linear relationships on the Cartesian plane. Students convert between units of measurement for area and volume. They perform calculations to determine perimeter and area of parallelograms, rhombuses and kites. They name the features of circles and calculate the areas and circumferences of circles. Students determine the probabilities of complementary events and calculate the sum of probabilities.
The following topics provide the framework for learning in Year 8 Mathematics:
Evidence of student achievement will be gathered through tests, investigations and other assessment tasks.
In semester 1 students will complete a research task on integers and indices and how this relates to units of temperature, represent statistical data using fractions, decimals and percentages, and use algebra to calculate doses of medicine to be administered at different ages. Students will be tested on their knowledge and understanding of integers and indices, fractions, decimals and percentages, and algebra.
In semester 2 students will complete a research investigation into the value of pi. They will also be tested on their knowledge and understanding of measurement, statistics and probability, linear graphs, and ratio and rates.
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
