Responsive Math Teaching (RMT) is an NSF-funded research project focused on improving mathematics instruction in a network of elementary schools through a research-practice partnership between Penn GSE and the School District of Philadelphia. The RMT project is built around five core components:

What is Responsive Math Teaching?


Responsive math teaching (RMT) is instruction where the teacher continuously elicits information about what students currently know and understand and responds in ways that move them forward in relation to developmental and grade-level mathematical goals. This occurs throughout the instructional cycle, which includes:

Responsive Math Teaching cycle, with a mathematical goal at the center, including plan; launch; facilitate productive struggle; make student thinking visible; connect to mathematical goal; build and expand; and reflect, consolidate, assess

  • Selecting and launching cognitively demanding tasks that are open to multiple entry points and solution strategies;
  • Engaging students in productive struggle, discourse, and collaboration;
  • Having students share strategies and defend their solutions;
  • Building connections and deeper and more sophisticated understanding of core concepts, strategies, and procedures;
  • Collecting formative assessment information to inform instruction.

Recognizing what students know and are able to do and leveraging that to move towards higher level reasoning and problem solving ensures equity and access to mathematics for all students. When the teacher responds simultaneously to student thinking and a mathematical goal, each and every student is recognized as a capable learner who can develop deep, meaningful, and flexible understandings.

Professional Development

The professional development program begins with the Experience year in which participants experience RMT as learners to reflect on and develop new teaching practices. In the second year, participants engage in Lesson Study and peer coaching, collaboratively planning, teaching and reflecting on RMT with students and other teachers. Finally, in year three, participants develop their leadership skills, learning how to support other teachers to adopt and refine Responsive Mathematics Teaching practices.

Teachers with one or more years of RMT experience participate in Lesson Study sessions with teachers from across the network working at the same grade level. In these cross-school planning teams, teachers and leaders engage in cycles of planning, enacting, and debriefing RMT lessons. The goal of Lesson Study is for teachers to improve their ability to plan and enact responsive math lessons.


Building Sustainable Leadership Capacity

The phasing in of school involvement allows for expertise to grow across the network over time and for schools to serve as resources for one another.
