The 2018 Refreshed SSHG curriculum is a great way to centre your instruction on Indigenous knowledge, experiences and perspectives. Take the time to become more familiar with some of the changes and begin to respond to the TRC Calls to Action in a good way. Teachers are enriched to contact the Indigenous leads in your boards and seek out resources that reflect Indigenous voice.
