The University of Arizona: IMPACTS Middle School – Ratios, Proportions and Proportional Reasoning (Grades 5 – 9) Part 2 of 2

Ratios and proportional relationships are critical areas for middle grades mathematics and are foundational for further study in mathematics and science, as well as being useful for everyday life. The teaching of ratios and proportional reasoning should build on students’ work in measurement and in multiplication and division in the elementary grades, while also further developing fraction sense as students move from additive to multiplicative thinking. Come and explore the learning trajectory, tasks, and student supports for proportional reasoning, in order to develop a deeper understanding of the Big Idea and the 10 Essential Understandings of ratios, proportions, and proportional reasoning. **NOTE: Participants will be expected to take a task back to their classrooms, collect and analyze student work, and share their reflections with the CRR.
