This online course will introduce teachers to specific strategies for engaging students in mathematics lessons and activities built around social justice issues; for example, healthy eating, living wages around the world, access to clean water, or fair trade. Teachers will explore the rationale for integrating these kinds of issues into mathematics curriculum, examine the guidelines for incorporating social justice lessons, and evaluate current research-based strategies for promoting critical thinking, problem solving, and reasoning within Common Core mathematics instruction. This course may be completed with or without students.
