Effective September 2021, all mathematics programs for Grade 9 will be based on the expectations outlined in The Ontario Curriculum, Grade 9: Mathematics, 2021. The content of this course should be used as a supplementary resource only.
Subject
Mathematics
Grade: 9
Credits:1.0
Type: Academic
Language of Study: English
Prerequisites:
None
Course description:
In this course you will develop an understanding of mathematical concepts related to algebra, analytic geometry, and measurement and geometry through investigation, the effective use of technology, and abstract reasoning. You will investigate relationships, which you will then generalize as equations of lines, and determine the connections between different representations of a linear relation. You will also explore relationships that emerge from the measurement of three- dimensional figures and two-dimensional shapes. You will reason mathematically and communicate your thinking as you solve multi-step problems.
