Kids have trouble with algebra. Like big trouble. Many of them suck at it...big time. I think that a lot of that comes from the fact that all of a sudden math gets really abstract and a lot more complicated than it was before. Take linear equations for example. In pre-algebra (where I taught at least) they learned about slope-intercept form. And we did tons of applications with it. Tons of scenarios that for the most part made sense to them. So they were for the most part comfortable with writing equations.

All of a sudden in algebra though, we have standard form and even more abstract point-slope form. And they all kinda represent the same thing (a line). Take a kid for whom math doesn't come naturally and they're going to have no idea what's going on.

I tried for this unit to focus on some of the applications of these equations. Especially so for standard form. I actually feel pretty strongly about starting standard form off with an application. I have always felt like standard form equations come naturally to many kids. Before mentioning anything about standard form, or even being linear, I had kids do this activity.

These problems and activity are so well thought out - thank you for sharing all of your great work!
