I found iFraming in Canvas and used it to embed a game from the NCTM illuminations math exercises into my little course. I'll also provide a link so that students can go there.
I'll want to make some quizzes that do the equivalent, but it's a neat option and worked quickly and easily. Hooray

(NOT a Canvas expert despite my points) Lots of background & experience helping students who struggle (whatever reason: learning disabilities, mismatched teaching, confidence) to understand math. I've evolved from reading specialist for students w/ specific language disorders ... I'm trying to design conceptual math lessons (as opposed to the procedure-based ones that it seems all the materials for older students have).
