Another lesson learned...

Or relearned. So here's this student who's been working hard all semester... but struggling. Rending of hair on my part because her instructor assigned relatively little homework - one and *maybe* two problems of each kind. As in, "if you can do these, you already know this stuff;" not to be confused with "here is some practice so you can *learn* this stuff." This student was very resistant to doing "extra" homework; it wasn't assigned!
However, when I showed her the practice with positive and negative addition on aaamath.com she worked on it for forty-five minutes and didn't want to leave when I had to go home.
This stuff would be outright "drill and kill" to many. However, she not only kept going with it btu figured out and verbalized what her error pattern had been.
(No, that's not all it takes. Lessons re-learned: the very same student can have what looks like a *completely* different attitude with a shift in the assignment. What's boring for me is not necessarily boring for you.)
