Alder Creek Middle School is a two-year school with about 700 students in grades 7-8. The school uses a teaming structure with five teams that loop with students for two years. All math teachers teach two levels of math each year to accommodate this structure. As a department, they have shifted to doing more collaborative professional development, sharing best practices, using common assessments and student discourse protocols. Through their participation in OMLI, they have focused on lesson planning frameworks, observations, and protocols for both staff and students. Going forward, they plan to continue deepening the curriculum, developing interventions, using data, visiting classrooms, and celebrating their successes together as a department.
