Mathematical modeling is the process of using mathematics to understand and make decisions about our world. As we think about our role in education, we take to heart our responsibility to use education to leave the world better than we found it and our call to empower young learners as knowers and doers of mathematics. Modeling is a practice we can draw on to create mathematically powerful spaces where students share their knowledge and perspectives to understand and address situations they care about. Modeling inherently provides opportunities for access, equity, and empowerment for each and every student. In this session, our goal is to help you conceptualize what mathematical modeling can look like in your classroom and launch you on the journey of becoming a teacher of modeling. We will discuss four big ideas that have helped us conceptualize mathematical modeling in elementary classrooms, explore examples of tasks, and share wisdom from teachers who have engaged in this journey.
