Webinar: Data Literacy Across the Strands   [MOV]

Students in Ontario are navigating a complex world driven by data. Our world is evolving and new fields and careers are emerging that require individuals with high levels of data literacy. Supporting students as they develop critical data literacy skills is an essential component of the new de-streamed Grade 9 curriculum. Data literacy is different from data management. Certainly, data management skills are important to analyse data. As part of the revised elementary mathematics curriculum in 2020, students have been building their data management skills. How do we connect these with the larger goal of achieving data literacy? What are the competencies necessary for data literacy, and how will we continue to build these competencies to ensure that all students leave our schools as data literate young adults? In this webinar, we will talk more about these competencies, and we will share strategies for integrating data literacy into the teaching of each of the math strands.

Lesson - Infinity Pool - Using Geometry and Coding to Explore Limits and Infinity   [GDoc]

This lesson introduces students to the concepts of limits and infinity through the lens of a practical geometry and measurement problem and through the use of coding and spreadsheets. Students will begin with a practical problem, then investigate, in a theoretical way, how increasing the number of sides of a regular polygon, while holding the perimeter fixed, influences the area of the polygon. They will create a pattern of polygon area calculations that tends to the largest area, a circle, by adding smaller and smaller increments. Patterns will be examined using tables of values and graphs, with an end goal of students understanding that the area will approach a limiting value. Students will then apply this new knowledge to the original practical problem.

Webinar: Course Planning   [MOV]

This webinar will introduce Ontario educators to three (3) course plans, each of which outlines a different way a teacher could structure the 2021 Grade 9 math course. These course plans have been shared on our OntarioMath.support website. Each course plan includes all of the curriculum expectations, providing suggestions as to how to group expectations to present mathematics in Grade 9 as a connected whole. In addition to providing ways to structure the course, each plan offers ideas for questions and tasks that will engage students with the mathematics they are learning. In this webinar, we will also outline the underlying principles upon which all three course plans have been designed to provide support for teachers as they implement a de-streamed grade 9 curriculum.
