I like hearing everyone else’s thoughts!

In your video, that slide of multiple representations is awesome! It goes way beyond the Big Five I stress in Algebra. I’ve also learned that it’s important to pick and choose what representations to use in one lesson.

Your double number line is something I need to explore more. This isn’t the first time I’ve seen it, but I’ve never used it to teach. Bar models are more my thing, but I see the relationship and want to try the double number line at some point and get comfortable with it.
