Interdisciplinary by Design is a professional learning session that helps teachers integrate literacy, language development, and content instruction in a more intentional way. By aligning ELA and Social Studies, it supports multilingual learners within everyday instruction rather than adding extra layers. The session highlights practical structures that can streamline planning, reduce redundancy, and create more cohesive learning experiences for students. It is designed to help schools strengthen instruction while making the work more efficient and sustainable for teachers.
