Students in Grade 9 continue to enhance their skills in algebra, particularly with regards to roots, radicals and the laws of exponents. From there, students study linear functions and linear systems, one-variable inequalities, properties of functions, probability, factoring and surface area and volume of composite figures. If time permits, students are introduced to other function families which they will study in Grade 10. Stanstead College offers an advanced level of mathematics in Grade 9. Students in this level will also study the basics of trigonometry, two-variable inequalities, permutations and combinations and quadratic functions.

 

Pre-requisite: Math 9 (85%) or department approval. The Science Option has students continuing to develop their capacity for abstract thinking in order to enable them to make a variety of connections among the different branches of mathematics. This option prepares students for pure sciences and courses that contain science prerequisites. Students make formal use of symbols, rules and conventions and are required to construct proofs. Students will study algebraic expressions (identities, second-degree equations and one-variable inequalities), real functions (step, greatest integer, quadratic and their properties and parameters), systems of equations (including semi-linear), two-variable distributions (linear correlation and regression lines), equivalent figures, analytic geometry (midpoint, division point and distance between points), metric and trigonometric relations. There is a Ministry exam at the end of the course in June.

 

The Cultural, Social and Technical (CST) option helps students develop mathematical literacy so they can appreciate the connections between math and other aspects of culture. Students following this option are preparing for study in the arts, humanities and the social sciences. This option provides students with tools to help increase their capacity for analysis, consider different possibilities, make informed decisions, support their decisions and take a position on various issues. They study algebraic expressions (first-degree inequalities), relations and functions (periodic, quadratic, piecewise and step), systems of equations, subjective probability, statistics and one-variable distributions (measure of position), two-variable distributions (linear correlation), analytic geometry (slope, distance, division point) and basic trigonometry. There is a Ministry exam at the end of the course in June.
