Help students see their whole selves in the math they're learning with culturally responsive teaching. This book aims to re-center mathematics as a humanizing endeavor because putting children and their humanity at the heart of mathematics education can result in more engaged, meaningful, and joyful learning. It introduces a model and a tool for Culturally Responsive Mathematics Teaching, constructed to create a safe, inclusive space where all learners can come together in their own educational journey and develop a love for math that centers their experiences and comes from the heart. Implementing the Culturally Responsive Mathematics Teaching Tool (CRMT2) will help you cultivate and sustain meaningful, rich, and rigorous mathematical learning spaces for all your students - experiences that foster mathematical curiosity and joy. The book walks you through each aspect of the framework and tool, guiding you to consider how your classroom structures, lessons, tasks, and assessments: honor the existing cultural strengths, experiences, and lived realities of all your students; elicit diverse mathematical thinking and ideas; support equitable access to rigorous mathematical learning and discourse for all students; invite a sense of agency in each student's learning experience; promote high engagement and excitement while learning mathematics; and nurture an understanding that mathematics is a powerful tool for making sense of the world. By weaving these strategies into classroom lessons, teachers can humanize mathematics instruction to successfully build a love for math while providing equitable learning opportunities that empower student voice and promote success in mathematics.
