Looking for ways to address the gaps in students' learning in Mathematics? Accelerate Mathematics Proficiency (AMP) is a learner-centered approach that builds on students' existing knowledge and advances them using a learning progression. This two-day, face-to-face session offers a process to provide real-time acceleration for students who may have unfinished learning. Day 1 will focus on building a mathematical community of learners and strategies for designing and using formative assessment to make "in-the-moment" instructional decisions. Day 2 will continue with the process by analyzing student work and creating extended learning opportunities by building on the student's conceptual understanding. In the weeks immediately following each full day of learning, participants will have the opportunity to engage in optional one-hour virtual follow-up sessions to gain support on the implementation of skills learned and earn additional professional learning hours.
