I compartmentalize a lot in this class. We learn a couple of skills, review, and quiz. No big unit/chapter tests (if you don't count the exam). But for systems I thought it might be nice to try and pull everything back together.
Ok, so you can graph/use elimination. But can you decide when to use what?
We're quizzing tomorrow on elimination/systems of inequalities. And then I think I'll spend the next few days on the process of making the decision of which method is most appropriate for the system (and then solving it).
I was shopping around for a foldable for the kids and their INBs today when I visited msmathwiki (organized by my friend and fellow TMC12-er Julie Ruelbach). There were several systems foldables linked there that I checked out and liked @druinok's the best. But I wanted to edit it a bit. So I emailed and Shelli, in her infinite generosity, sent me the word doc.
Here's what I ended up with:
Here's the pdf. (Shoot me an email if you'd like the editable doc!)
And just for fun, I made copies on some pretty pink paper. The boys'll love it.
