The One With the Graphing Project Page (Number 2)

Image

Admittedly, I’m not backwards planning this summer unit as well as I’d like to. We spend Fridays working on a summative-esque project page. Last week, we used real data to make graphs. This week was supposed to be more of a focus on using linear functions to make predictions, but we ended spending a worthwhile day making a table and then a graph from a situation. (I also wish we’d done something with equations, but that’s for another time).

The One Where the Equation Pushes the Representations

Image

In our abbreviated summer program, we’re going through linear functions. Kiddos are great at tables and pretty good at graphs. So now it’s on to using equations to generate those representations.

I feel like we could probably push more on what the different parts of the equation mean (slope, y-intercept) and I almost wish we were doing more with really big numbers (to make using an equation worth it rather than just counting or multiplying), but it feels important to build intuition around how to use linear functions and equations.2017-06-29 13.52.56-2

The One with the Extension

Image

Our school/summer program works with a wide range of prior student knowledge. As such, I feel like teachers sometimes talk about whether they feeling stronger supporting students with interrupted education or students who need more of a challenge (the two extremes of the spectrum). For whatever reason, I often think of myself who is (mildly) better at supporting students who are struggling.

So I’m pretty pleased with how Wednesday’s extension went. We started with a 3 Reads problem that I’ve done before (the first one I ever wrote and, surprisingly, one of the strongest ones I’ve taught). It ties in pretty well with the content we’re studying right now – linear functions and volume. Most of the class tried to figure out how many boxes there were be if a certain number of boxes kept appearing every day. The one group that was farther ahead got yardsticks and had to estimate if all the boxes would fit on the third floor, which involved actual estimating and modeling (if you think I’m letting kiddos out into the hallway to roam free during last period, you might be confused).

The One with Graphing Negatives

Image

One of the weaknesses of the curriculum we wrote for the school year is that it mostly focuses on graphing in the first quadrant. As I was reminded while writing and pulling activities for this summer, that’s where many of the “real world” problems are. (I know, I know. Not all math needs to be “real world”)

Fortunately (and as a reminder to my future self), problems with money and days can extend into work with negative numbers. My Summer Planning Partner also came up with the idea of using a 4-quadrant axes regardless of where the numbers fall (at some point, School Year Planning Partner and I made the decision to print 1st quadrant graphs so that kiddos could focus on bigger, more easy to see points. Maybe I regret that?)

The One with Realish Data

We are trying to align our curriculum to the biology curriculum, which has to do with waste management. For our Friday Project Page, we find a few interesting graphs from an actual report. One kiddo asks what MSW is and I have to google it during first period (Municipal Solid Waste, in case you were wondering). I wonder whether the tables and language might have been just a bit too academic, but #IRegretNothing (well, I don’t regret much)2017-06-23-14-50-28.jpgPhoto: Data and graph. Gotta revise those axes.

The One with the Linear Representations Scaffold

Image

One thing I’m finding, 3 weeks (to the day) into summer school, is that when in doubt, lean on your routines (I’m fairly certain I read this in Carl Oliver’s blog, to give credit where credit is due). We have about 5 weeks with 50 minute classes, so there is not much time to teach or to plan (let alone condense everything into a cohesive, project-based unit that may or may not sync with the biology class next door).

It’s taken me a while to remember this, and to get back into it.

I do recall that one of the structures that was most successful from our linear functions unit is the multiple representations paper (It says “Different Representations” on the actual paper and that is how the kiddos largely refer to it. Change it? Leave it? The eternal dilemma…)

For some reason, the kiddos love this one. There’s enough to talk about, there are different sections, and (added benefit of teaching summer school to some awesome multilinguals, many of whom I taught some portion of the year to) enough kiddos know something about the things that we’re seeing that most kiddos have some access to the content but still need to practice what goes where in the table or why we don’t just put the y-numbers from the table on the y-axis.

I’m also fairly certain that only our school talks about “Figure X” as I had to stop class and review it every time. It’s sometimes a bit too complicated for my tastes, anyway (but makes a nice stretch point).
