On their homepage for the Math Equity Toolkit, they write:
A Pathway to Equitable Math Instruction is an integrated approach to mathematics that centers Black, Latinx, and Multilingual students in grades 6-8, addresses barriers to math equity, and aligns instruction to grade-level priority standards. The Pathway offers guidance and resources for educators to use now as they plan their curriculum, while also offering opportunities for ongoing self-reflection as they seek to develop an anti-racist math practice. The toolkit “strides” serve as multiple on-ramps for educators as they navigate the individual and collective journey from equity to anti-racism.
Lots of jargon, but basically, the Bill and Melinda Gates-funded math, tells educators to focus on their biases. It assumes all whites are racist.
