Our Mission
The Delaware Mathematics Coalition’s mission is to identify, endorse, and design high quality synergistic professional learning opportunities and experiences that support the actualization of research-based norms for teaching and learning mathematics.
As an organization, the Coalition advocates and supports at the state and district levels for the implementation of these practices in every classroom so that all students gain the mathematics proficiency necessary to graduate having successfully completed a rigorous, meaningful twenty-first century education that prepares them for careers, college, and citizenship.
Our Impact in Numbers

Math Professional Learning Opportunities
Keen Eye Video Analysis Coaching

January 3rd
Keen Eye workshops are purposefully designed to help instructional leaders develop the skills and knowledge to support their teachers in achieving more ambitious mathematics teaching by maximizing the impact of their pre and post-lesson video analysis conversations.
As part of the professional learning, teacher leaders, coaches, connectors, and mathematics specialists will explore the essential elements of high quality conceptually-focused mathematics teaching that translate into more ambitious teaching by experiencing “keen eye” learning cycles. Learn More
Leadership Coaching Lab Community

January 9th
The promise of secondary Leadership Coaching Lab (LCL) is to build a robust mathematics leadership community in which the role of curriculum, lesson study, video analysis, and teacher growth are public and itself the focus of study among colleagues. Across the year, sessions provide Leadership Coaching Lab participants with recursive opportunities to reflect on their instructional practices, engage in mathematically intense conversations, and develop a keen eye for the essence of the mathematics in their conceptually-grounded lessons.

Transforming and Understanding PL

January 17th (Grades 4-5) & 25th (Grades 6-7)
The Transforming and Understanding Professional Learning (TUPL) is a 4-year curriculum and content-focused professional learning project designed specifically for Grades 4-7 teachers in districts using the Bridges Mathematics and Illustrative Mathematics Programs. Participants engage in five days of professional learning across the academic year as well as a three-day summer Math Camp. Teachers study the content and author’s intent of their high quality instructional materials and work side-by-side with the project Connectors to unpack, enact (and capture video), and debrief their target lessons. To learn more, check out the flyers below.
