So, there are a few other blogs on my own personal list, that I read occasionally. One of them, the math Curmudgeon, is, as you will see, not a fan of SMART boards. However, regardless of any differences of opinion we might have about SMART boards being useful, I think you’ll also look at the goof he found and go: wow. I know a few of you played with this app in SMART Notebook a few weeks ago: it lets you make some right triangles, and tells you the side lengths and the angles. The only problem is that it’s wrong! The side lengths and angles are incompatible (try making a trig function with it, and it will become apparent how far off it is). He’s got a description here (and a few uncomplimentary words) along with a screen shot.

(It’s these sorts of things you don’t notice about a new textbook or a new piece of software until you’re in the middle of it, and everything is goofed up–glad I haven’t tried using that one in a class!)
