Tonya is passionate about learning about and supporting teachers in developing equitable mathematics instructional practices that recognize and transgress systemic inequity. She understands that issues of culture, race, ethnicity, identity, and power influence students’ opportunities to learn and teachers’ opportunities to teach mathematics and that these factors must be explicitly discussed and addressed if we hope to fully support equitable mathematics teaching and learning. Tonya is honored to have participated in the writing of this book and in continued efforts supporting mathematics education that explores, understands, and responds to social injustice and supports students’ learning of mathematics.
