We then reveal the secret behind the magic:
We then talk about working "backwards" and "undoing" the steps (doing the inverse operation/opposite).

In opener #2, I'd make the instruction "multiply" instead of "simplify."
ReplyDeleteI've done this same activity with a similar flowcharty-y visual. It works well, and today would be a good day to make sure everyone understands and can use "inverse." (Although if students still say "undo," that's fine.)
Are you concerned that this lesson is a bit short? What's the plan if it is short?
Raymond - Made the change on multiply in my opener, thanks.
ReplyDeleteThe plan if it's too short (although last year we never finished early) is just to do a few more similar to the last two slides.
