Hi Teresa, I have not found a Canadian Curriculum for the 9th grade. There is a Grade 6th Ontairo which is probably the one you the child is on. When I checked the Ontairo curriculum for 9th grade online it looks as if there are two different math tracks. When there is no specific mission on Khan Academy, you or someone else must create a playlist of relevant videos and exercises based by identifying which material on KA (most likely from the Highschool or possible 8th grade missions) best support the curriculum. Most people find a spreadsheet to be helpful in this process. If you cannot find one, and decide to create one yourself, I'm sure there will be other home schoolers who are interested!

I would like to change from grade 7 to grade 6.

Thank you
