17:58Algebra  The rich get richer
One interesting thing that happened was that the two classes moved through a classroom exercise with algebra tiles at very different rates. As a consequence, the first class got only a cursory overview of how to factor trinomials with a minus sign, while the second class got a very good overview. It will make for an interesting class on Monday to see whether the kids read through the section as instructed before attempting the homework. Worse still, when I looked at the homework, I saw that not one assigned question was in the form ax^{2}+bx+c! They all had at least one subtraction in them, and most had the third term negative, which was the form that the first period kids got the least exposure to! (And I keep writing with exclamation marks!)
I did get some sense of what sort of questions will be raised on Monday, though, since I had one student come in after school to take a quiz and she asked me about some of the homework questions she had done and why her numbers didn't match the back of the book.
