This training is a prerequisite for AMSTI 6-12 Math Content Area Trainings. This one-day session focuses on providing an overview of pedagogical strategies, student mathematical practices, mathematics teaching practices and formative assessment cycle making connections among grade-band standards and strategies to the ALCOS. Participants will explore student-invented strategies, analyze evidence of student understanding to inform planning of next instructional steps, discuss the importance of sense-making, and explore the impact of concrete, semi-concrete, and abstract learning opportunities on the development of conceptual understanding.
