I found this resource as I was searching for curricular materials for teaching Metis heritage, history and culture. The “Best Practices -Including First Nation, Métis, and Inuit in the Curriculum” resource was created by the Bruce-Grey Catholic District School Board from Ontario. The resource is designed to support teachers in a culturally responsive way in teaching First Nations topics. The resource defines potential problem areas in terms of Key Concepts, Accuracy, Culture, Authenticity, Diversity, Eurocentrism, Pedagogy, Use of Terminology, and Visual Images and gives teachers concrete language they can use to cover these topics in a culturally appropriate and sensitive way.
The resource can be found here: Best Practices
