Year 9 Mathematics
Note: The chapters referred to below relate to the text we previously use at Cornerstone (Cambridge Essential Mathematics for the AC). We now use the CORE edition so this page will slowly be updated as we work though the course.

This site contains all the details of what students are expected to be learning in each year at school. Some of the more useful elements are the sample portfolios at the bottom of each year level, which give examples of satisfactory work at each year level. Note that the mathematics content is the important point, not the neatness of the handwriting or drawings!
