Central objective: Mixed-ages — practical guidance for early childhood educators and child care centers working with mixed-age groups. Supporting elements: a curated set of resources and templates including Creating a Culture of Safety for Mixed Ages, culturally responsive oral-health practices, bus sign-in sheets, active supervision guides (on buses and in settings), weather-appropriate activities, disaster preparedness education, and a mixed-ages weekly lesson plan template. Use these tools to improve safety, supervision, inclusion, and lesson planning across mixed-age classrooms and programs.
