A multiage approach in education has been used successfully in numerous schools across Canada.These sites will give you a better idea of the research being conducted and experiences using a multiage approach in classrooms. I've included links below to explore more of what each province/territory is doing. I realize there may be classrooms and research I haven't included, and not for every province/territory, please feel free to add any additional websites in the thread at the bottom of the page and I will add them in. Thanks!
