The One with the Linear Representations Scaffold


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 Oliveri’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).

The One with the Big Numbers

We’re doing linear functions for summer school and pulling hard from last year’s curriculum. This means using CPM’s pile patterns (which I cheat and just refer to as “patterns”. Who wants to explain what “pile patterns” is to a class of (amazing) emerging multilinguals, when there’s so much else you could be teaching).

Kiddos glom on to the idea of patterns pretty readily, which is great. They’re visual and you can ask “how many?” and point without requiring too much language (my big takeaway this week).

I get to tinker with this class a bit more and we have less time (5 weeks, 5o minutes a class), so I cut some stuff.

For the patterns, we usually jump from finding the 4th and 5th figure to finding Figure 99. This has always been a bit of a jump for me, especially for kiddos with Interrupted Education who may not make connections to the idea of repeated addition and multiplication.

I spend quite a bit of time in class saying, “Sit down, Jeronimo” (not the kiddo’s real name). But he really grabbed on to this task. While many kiddos struggle to anticipate the figures beyond the ones they can see (or ones one or two our), this kiddo made his own chart to help track numbers. Pretty awesome.

The One with the Patterns


Week 3 of Summer School, though I don’t know if the first 3 day week actually counts.

In what is maybe not the most cohesive move, we start a new unit on linear functions and graphing this week (Goodbye area and volume). I largely pull from our linear functions unit from this year which largely pulls on CPM (credit where credit is due).

He catches on to the patterns quick (and also has a helpful habit of saying “Wait, we learned this already”, which gives me some hope that what I teach may stick around for longer than the 65 minutes I usually see kiddos) and is quick to point out that the sentence structures for the opening are the same for this entire week (thanks, Estimation180).

He also carries over some unusual conceptions from the school year (that many other kiddos carry), including how to generalize figures with more squares. Admittedly not the most useful skill and probably not Common Core-approved, but it reminds me that I need to push kiddos to explain what the square represents and ground them in familiar concepts like base and height.

The One with Individual Tangent Practice


I’m a bit more into individual practice, these days. A few years ago, I think I was more “all groupwork, all the time”, but I’m appreciating the fact that a decent culture of groupwork at our school helps support our kiddos when they’re working individually while also allowing them to spend time on what they need.

We’re still working through how reference angles are related to tangent ratios (without really calling them that – most kiddos are sticking with opposite and adjacent sides). Also trying to balance procedural work (especially with ratios) and conceptual thinking. Someone made a decision with this curriculum to round some of the tangent ratios to numbers that made it easier to solve for unknown numbers. While this may take away from the actual ratios (which are a calculator button push away, anyway), it did give a lot of kiddos access who weren’t familiar with solving ratios. Lots of struggle today and I’m hoping kiddos got something out of it.2017-03-10 17.39.31-2What do you notice? What do you wonder?

The One With Ratios


We’re onto right triangle trigonometry. This year is flying by (and we’re a few days in at this point).

One of the many tricky things about right triangle trigonometry is that ratios are big. For classes where some kiddos don’t really know how to divide (let alone when it’s written as a fraction) while some (one) roll their eyes because the conceptual trigonometry we’re using has an approximation rather than the actual tangent ratio, the need to differentiate is real.

We took a bit of time today to talk about how to solve ratios. How many kiddos did we actually reach? Unclear, but the first step is important.

It’s fascinating for me to see the 4 papers I used (one per period) to show how to solve an with a variable in the denominator. By the end of the day, I’d realized that writing fewer steps cleanly is more important. I’ve also decided on “one finger if you understand, two fingers if you’d like to hear it again” is a nice way to hear what the class is thinking without being too judgemental (I’m so used to thumbs up/thumbs down, but that feels weighted).

We also did a reading guide where the kiddos used calculators to find the tangent ratio. It’s actually something that I remember relatively vividly from student teaching. I’m feeling a deep appreciation for this unit the third time I teach it.
