In collaboration with communities and other organizations, The Gordon Foundation has developed an online resource website called https://understandingtreaties.ca/ to support learning about Treaty negotiation through simulations. This interactive learning exercise reminds me of model UN clubs, and seems like a great exercise for students to practice self-determination whether offline or online. It is designed with actual negotiators from band offices and grounded in the histories of treaty negotiation in Canada.
The program uses plenty of mixed media, including these illustrated texts: https://understandingtreaties.ca/wp-content/uploads/2021/05/Series-1.pdf
I discovered this initiative through a YouTube video recording of Nisga’a Nation youth participating in the treaty simulation.
