Right now in algebra, students are just wrapping up graphing systems of inequalities. According to my exit slips/formative assessments they are pretty good at it.
I spent a whole lot of time the last couple weeks digging around for activities and resources on rich problems involving systems of inequalities. Here are a couple of my favorites:
–Ohio Jones by Dan Wekselgreene
–Lego Pieces by Fawn Nguyen
I regret not using either of these this year.
However, I am in a weird position that I haven’t ever really found myself in…
Normally when I find an activity/task I am excited about I go for it, without any hesitation. Right now though, I feel a pressure just to get through the content. I dunno, I guess I am trying to say I don’t really feel like spending extra days exploring and setting up struggle for students with this particular concept.
And I am normally all about that.
I started teaching linear inequalities by asking students how many solutions various equations have…
y = x + 3
lxl = 5
y = x + 3
y > x + 3
It took so much time to get through one linear inequality and I am not sure what value this approach has over just telling students the short cuts of shading/line types. It does not feel to me that the time we sunk into it was worth it. The transition from pure math or interesting problems into using a system of linear inequalities to solve them is rocky. Hopefully by next year I will have some time to think and come back with a better understanding of my struggles right now!
