This session will walk through the progression of a mathematics unit: building relationships with teachers; co-planning, honouring students’ cultures; redesigning a mathematics task to include cultural relevance and meeting the needs of students' IEPs; celebrating student voice; and long-range planning using mathematical modeling. I will share data that shows how student engagement and achievement are affected by redesigned practices that include BTC, UDL, and DI principles. Participants will have the opportunity to bring their own examples and adapt curricular mathematics tasks to embed with students' cultures and lived experiences.
