We started on section 1.3 today, and BOTH of the examples in the first demonstration page on how to find the equation of a line were wrong. How do they expect kids to learn from this?
It really gets me questioning my methods, too -- I have to keep trying it over and over again to convince myself that I really am right and the book is wrong. Even when I come up with a formula and plug one of the numbers in and it comes up with the other one, I still have doubts, just because BOTH of the "solutions" they show are wrong. God knows what the KIDS are thinking!
And the teacher hasn't once come forward in a discussion post or anything to say, "oh, by the way, there's this problem with such and such, so please ignore it," so I have to think nobody's asked her about any of these things yet.
We're going to be having a serious talk soon.
