Any comments on Math U See? Good, bad? Did you start in K or in another grade? Anyone use it all through middle and high school? That is what I am thinking of. My daughter is starting 5th, and I know from her older brother's experiences that once they get into 8th or so math loses me! I may have the anwswer book, but that doesn't help me teach how to do it. Math is and always was my weak subject! Math U See goes all the way through trig so that should do me. I want to hear how wonderful it is, or not...
