Empower children to be the change - join the teaching mathematics for social justice movement! We live in an era in which students of all ages have - through media and their lived experiences - a more visceral experience of social injustices. However, when people think of social justice, mathematics rarely comes to mind. With a teacher-friendly design, this book brings early elementary mathematics content to life by connecting it to the natural curiosity and empathy young children bring with them and the issues they experience. Tested in PK-2 classrooms, the model lessons contributed 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 justice issues. Learn to plan instruction that engages children in mathematics explorations through age-appropriate, culturally relevant topics such as fairness, valuing diversity and difference, representation and inequality, and environmental justice. Features include: content cross-referenced by mathematical concept and social issues; connection to Learning for Justice's social justice standards; downloadable instructional materials and lesson resources; guidance for lessons driven by children's unique passions and challenges; and connections between research and practice. Written for teachers committed to developing equitable and just practices through the lens of mathematics content and practice standards as well as social justice standards, this book will help connect content to children's daily lives, fortify their mathematical understanding, and expose them to issues that will support them in becoming active citizens and leaders.
