The topics on this page are what I would consider some of the “Big Ideas” of the MPM1D Grade 9 Academic Math Course to assist you in your course review and preparation for the EQAO Grade 9 Assessment of Mathematics which is worth 20% of your final grade. There are four (4) content strands in the course, so I will organize the topics based on strand and only include what I would consider the most important and/or common difficult concepts that all students should review over these last two weeks.
Note that you can find a full course review by clicking here.
