Study Notes
Released Grade 9 Mathematics Assessment Questions
- This resource supports educators using the EQAO Grade 9 Assessment of Mathematics (2021).
- Each question maps to a knowledge category and an overall and specific expectation in The Ontario Curriculum.
- Definitions of knowledge and skills categories are included, along with adapted assessment questions.
- Detailed information about each question, including its overall expectation, knowledge category, and correct answer, is provided.
- The assessment is online, computer adaptive and completed at the end of the Grade 9 course.
- It assesses knowledge and skills in number, algebra, data, geometry and measurement, and financial literacy.
- Mathematical thinking and making connections, and social emotional learning are not assessed.
- Students complete questions related to the categories of knowledge and skills throughout the assessment.
- The assessment questions follow a blueprint, and each student completes a comparable number of questions from each strand, enabling year-to-year comparison.
- The EQAO Grade 9 Assessment reports overall achievement levels, not scores per strand or knowledge category for individual students.
- Detailed reports on a strand/skill basis are available at the school, board, and provincial levels.
Definitions of Knowledge and Skills Categories
- Knowledge and Understanding: Questions in this category require students to demonstrate knowledge of subject-specific content and understanding of its meaning and significance.
- Example: A question about the linear relationship between the cost of an activity and the number of people participating.
- Application: Questions in this category require students either to select the appropriate tool or gather and apply necessary information to solve a problem.
- Example: A question about calculating the cost per person for an activity given a table of values.
- Thinking: Questions in this category require students to select and sequence tools or demonstrate a critical thinking process (e.g., reasoning). Students must make a plan to answer the question.
- Example: A question using a table of values to determine the number of people participating in an activity given a specific total cost.
Suggested Uses in Class
- Questions can be used without answer options to encourage student discussion about methods and common errors.
- Technology can be used to record instant student responses for discussions about correct answers and errors.
- Questions can be used as pre- and post-assessments, or as revision tools.
- Manipulatives and examples are recommended for students to use with questions.
Data Analysis, Collection, and Representation
- A correlation coefficient (r) represents the strength of a linear relationship between two variables.
- A strong negative correlation (correlation coefficient closest to -1) indicates a strong inverse relationship.
- A correlation coefficient of 0 indicates no linear correlation.
- Box plots visually represent data distribution.
Geometric and Measurement Relationships
- Geometric problems often involve relationships, like between a rectangular frame and a second frame with altered dimensions.
- Area calculations and characteristics of 2D and 3D shapes are necessary.
Financial Literacy
- Students can create monthly budgets.
- Monthly expenses are compared to the monthly income to modify the budget or check for its adequacy.
