Day 21: The One With Simplifying Algebra Tiles and Perimeter Challenges

Image

Curriculum partner and I sensed that 10th graders and students who had seen more simplifying with Algebra Tiles were getting restless, so we split the kiddos into homogenous groupings. We always try to frame this as letting students challenge themselves with students who need similar challenges.

FASCINATING to watch some of our newer students who frequently hide in the shadows start to step it up (and also to see 10th graders using tiles and expressions in a more meaningful way).

Photo: “We don’t speak any English!” said one newbie (in Spanish). But that didn’t stop them from a) using the tiles and b) saying the names of the tiles in English.2016-09-13-10-45-24-2

Spent about 45 minutes after school with the Littlest Advisee, revising a quiz. It’s a slow process that (currently) involves me reviewing the problems they missed and then them showing me they can do the problem (with help). If they can do the problem, I’ll give them half credit (up from 0, in this case). If they can do a different version of the same problem, on a different day, I’ll bump their score up as if they had just taken the test.

Spent another few minutes helping one of last year’s kiddos with his homework. Compound interest. What is that even? #PleaseHelpCantMath

Day 59: The One with the Exit Ticket

2015-11-13 18.58.14As a whole, our school has chosen to focus on differentiation. This is particularly relevant, given that the recent immigrant population at our school means that some kiddos have done formal education for years (actually some of the best schools in their country, we’ve been told) while sitting next to students who studied for a few years, then dropped out. (This is not entirely an exaggeration, though I usually try not to place students in the same group that have such a wide academic gap between them).

We teach simplifying and solving every year. It’s actually one of the few topics (along with area) that we’ve taught every year of this course sequence. This means that some students have seen it and know it, while some students have never seen it.

So, we gave them an exit ticket. We spent one day going over simplifying with algebra tiles and then asked them to show us what they know. This can be tricky since one day isn’t quite enough for some students to dust off what they learned last year while others might have been confused because they can solve equations, but never learned how to use algebra tiles.

This is an exit ticket from a kiddo who I taught last year and did good work with algebra tiles. They are able to draw representations with the tiles but didn’t correctly use them to solve the equations. Also, I made them gave me my pen back afterwards (I don’t think they’d thought I’d noticed at first)
