### Ontario Mathematics Curriculum

"The mathematical processes cannot be separated from the knowledge and skills that students acquire throughout the course. Students must problem solve, communicate, reason, reflect, and so on, as they develop the knowledge, the understanding of concepts, and the skills required in the course."

*The Ontario Curriculum, Grades 9 and 10: Mathematics*

The mathematical processes are:

- problem solving
- reasoning and proving
- reflecting
- selecting tools and computational strategies
- connecting
- representing
- communicating

*Taken and adapted from** **The Ontario Curriculum, Grades 9 and 10: Mathematics*

*For more information about the seven mathematical processes, watch the video "*Targeted Implementation and Planning Supports for Revised Mathematics (TIPS4RM): Mathematical Processes*".

"This course enables students to consolidate, and continue to develop, an understanding of mathematical concepts related to number sense and operations, algebra, measurement, geometry, data, probability, and financial literacy. Students will use mathematical processes, mathematical modelling, and coding to make sense of the mathematics they are learning and to apply their understanding to culturally responsive and relevant real-world situations. Students will continue to enhance their mathematical reasoning skills, including proportional reasoning, spatial reasoning, and algebraic reasoning, as they solve problems and communicate their thinking."
