A headline reads, “Two out of three Americans owned a smartphone in 2015.” Does that mean two out of every group of three Americans? Is it possible to have a group of Americans who all own smartphones? Adults encounter ratios and proportions all the time in news or media statistics, estimates of risk, shopping for the best deal, creating mixtures and recipes, and countless other daily activities. The ability to reason about these numerical relationships develops over a long period of time and through deliberate exploration of the mathematics involved. Language teachers can provide opportunities for students to encounter and expand their ability to reason with ratios in real life contexts.

Mathematizing ESOL III: Integrating Ratio Reasoning is a course for English language teachers who want to deepen their own conceptual understanding of ratios and proportions and to learn strategies for helping students build ratio reasoning skills. This course is for participants who have successfully completed Mathematizing ESOL I and Mathematizing ESOL II. MESOL III is a 6 week, asynchronous, facilitated online course with an additional final project for Massachusetts participants who wish to earn Professional Development Points (PDPs).
