I am taking the numbers and operations course by myself. I took the "Math-What's the Big Idea?" over the summer and loved it, but I am struggling with the first two lessons of this one. I think my problem is my approach-I have been a Reading consultant for many years, but now I am teaching Special ed. middle school math to CD and LD students. Needless to say, I am very visually oriented. Anyone have any tips for me?
