Mathematics 9 Course Outline
2012-2013
Ms. Keddy
A major emphasis in this course will be to encourage and enable students to gain
confidence in their mathematical abilities, become better problem solvers,
communicate mathematically, and understand the value of mathematics in their
everyday lives. In Math 9 students will continue to develop skills and concepts
learned in grade 7 and grade 8, as well as discover and learn new outcomes for
grade 9.

General Information
π
All math work must be completed in PENCIL. Work done in pen will NOT
be accepted.
π
Practice questions will be assigned on a regular basis. While these questions
will not always be collected and marked, the completion of these questions is
essential to the development of concepts taught in this course and must be
completed. Additional questions will often be provided for students who
need/wish to have more practice to solidify concepts and ensure
understanding.
π
If you miss a class it is very important that you find out what was covered
that day. Please see me beforehand if you know you will be absent the day
of a quiz or test. Assignments are due on the assigned day at the beginning
of class.
