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, including recipes and other contexts (thus the title!). The teaching of ratios and proportional reasoning should build on students’ work in measurement 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.
* In-Person participants are invited to come 15 minutes early and enjoy a continental breakfast.
