Thousands of teachers around the country have taken the Black Lives Matter movement into the classroom in an effort to stop the school-to-prison-pipeline and combat institutional racism in education. From Seattle to Philadelphia and beyond, teachers declared the first week of February as Black Lives Matter at School week and built a truly powerful national action. This movement holds the potential to unite parents, students, educators, and their unions in an uprising that can win important victories in the short term—such as ethnic studies programs, restorative justice, and the hiring more Black teachers—while helping lay the basis for a larger movement for Black liberation.
