Empower young adolescents to be the change-join the teaching mathematics for social justice movement! Students of all ages and intersecting identities-through media and their lived experiences- bear witness to and experience social injustices and movements around the world for greater justice. However, when people think of social justice, mathematics rarely comes to mind. With a user-friendly design, this book brings middle school mathematics content to life by connecting it to issues students see or experience. Developed for use by Grades 6-8 educators, the contributed model lessons in this book walk teachers through the process of applying critical frameworks to instruction, using standards-based mathematics to explore, understand, and respond to social injustices. Learn to plan daily instruction that engages young adolescents in mathematics explorations through age-appropriate, culturally relevant topics such as health and economic inequality, human and civil rights, environmental justice, and accessibility. Features include: content is cross-referenced by mathematical concept and social issues; connection to Learning for Justice's social justice standards; downloadable teacher materials and lesson resources; guidance for lessons driven by young adolescents' unique passions and challenges; and connections between research and practice. Written for teachers committed to developing equitable and empowering practices through the lens of mathematics content and practice standards as well as social justice standards, this book will help connect content to young adolescents' daily lives, strengthen their mathematical understanding, and expose them to issues that will support them in becoming active agents of change and responsible leaders.
