IMPACTS-MS Ratios, Proportions, and Proportional Reasoning

September 18, 2021

Ratios and proportional relationships are critical areas for middle school 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.

(Activities will be different from last year’s Ratios workshops, so teachers who attended last year should still consider attending this year’s workshop.)

NOTE: This is a TWO PART workshop. Participants will be expected to take a task back to their classrooms, collect and analyze student work, and share their reflections with the group.


***Teachers from Arizona schools are invited to apply at no cost. Others may register for $60.
