In this session, we will review three MLL Instructional Material Design Features for core math materials: - Mapping Content and Language Development - Monitoring Content and Language Development - Making Connections through Student Collaboration and Conversation and unpack their role as “ignitors” to effectively support mathematical language development along with deep math learning. Join us to discuss how informed choices can reduce disparities and create equitable opportunities for multilingual learners in mathematics education. Walk away with a deeper understanding of these 3 “Materials Must-Haves” and tools to embed these in your adoption or implementation plans.
