MEC Teacher Mathematics Leadership development is for local cadres of current and future mathematics leaders. These teachers, math coaches and others, comprise the Local Math Support Teams (MSTs), and are immersed in summer mathematics content courses and six days of leadership follow-up each school year. They serve as leaders and mentors within their schools and communities during and beyond the scope of MEC support. MSTs are also prepared to lead community Math Nights, Numerical Reasoning workshops and other sessions to facilitate and sustain continuous learning and access to high-quality mathematics for every student.
