Grade: 9

Level: Academic

Prerequisite: None

*This course enables students to 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. Students will investigate relationships, which they will then generalize as equations of lines, and will determine the connections between different
representations of a linear relation. They will also explore relationships that emerge from the measurement of three-dimensional figures and two-dimensional shapes. Students will reason mathematically and communicate their thinking as they solve multi-step problems.*

The textbook for this course is Principles of Mathematics 9 by McGraw-Hill Ryerson. A replacement costs around $90, so be sure to take care of it.

### Exam Review

There is a Course Review section toward the end of your textbook. MathWiz is another great resource for exam review questions. Mr. Silvaggio has also prepared a package that you can download and work on.
