HOoks and ladders :)

September 30, 2015


THat doesn’t really have anything to do with anything, but I did see a truck carrying an entire utility pole on it this morning. I also saw SVABBY2 again – but I think she’s found a different route. (THat’s the license of the VW driven by the lady who passed me on the right then […]

More khan fun

September 26, 2015


So I went back to Khan Academy to see what color they used for their layout,(and now I realize the answer to my question:   what shade of blue will be pretty but not too dark to see white text? is … right here on my blog…) I now, on this second day, can do […]

Badges and bells

September 25, 2015


I’m scoping out design ideas so I wandered over to Khan Academy, among other places… and it looks really nice. It’s encouraging… there are a million badges you can earn… I like that when you’re presented with a problem you can click and watch a movie about it right then and there, though the movie […]

Why subtracting is harder, maybe

September 25, 2015


So I made a handout about adding and subtracting integers that’s a visual nightmare so I’m not even sharing it. In the process, I’ve got a hypothesis about why every semester students seem to get adding integers reasonably well and then explode when subtraction gets dumped on them. I realized that there are four possibilities […]

It’s about the strategies and stuff.

September 25, 2015


Today I had three folks in here working on pretty much exactly the same ALEKS problems with fractions.   One of ’em has figured out that … she needs to understand the stuff to do well, and that’s going to take extra work.  She came in with the typical proclamation that the teacher had gone […]

Slow processing :)

September 24, 2015


Sitting here waiting for the emulator to load up just to make sure it what I submitted *will* run on the device it’s supposed to run on. Realized that the waiting period would be a good time to watch the videos on the same stuff, tho’ hopefully I won’t have the need to try […]

The jury’s out …

September 23, 2015


or, actually, I haven’t had to report in for jury duty today or yesterday, so I’ve gotten to go to work, where it’s not crazy busy (in part because people knew I might not be here but mainly because of timing of tests, etc). So, no free hours to sit and doodle and speculate… I’m […]

Small but significant victories

September 22, 2015


“How can you have a set that’s equal and not equivalent? You can’t.” It’s wonderful to hear a student who isn’t locked into “What’s the formula to get the answer?” and automatically includes “no, that just won’t work,” without stress…

Time to what?

September 17, 2015


Thursdays are usually the quietest — most of the Math courses I help with are M, T, W, Fr classes. I arrived in my office at 8:02; one student was already there.   Three more arrived in the next five minutes; I worked with about a dozen folks… in the first hour.   Got to […]

Don’t want to forget the movies …

September 12, 2015

2  — this is a quick video showing finding the mean as “leveling off.”   It’s done with number rods and it’s short and sweet (and not too many words).   I’m not sure students would see the connection between that and means in the context of real situations but that could be addressed. A […]
