Another EM detest-er here. My oldest had it for three years in K - 2 grade. She was amazing in math in preschool. She could add, subtract, multiply, and divide prior to starting K.

By the end of 2nd grade, she wasn't adding, subtracting, multiplying or dividing. She was completely lost and confused. I changed schools, got a tutor, and after three more years she loved math again. (She loved math; it was her favorite thing prior to K. But after K, she had a burning hatred for math. She also thought she was slow in math because she was so lost in it.)

Today, she is a freshman in Pre-Calc who thinks the class is easy. She loves math again. It was always her forte, but EM nearly destroyed her passion. I'm glad she found her way back, but it did take some money and time with tutoring in late elementary to undue all the crap of EM.
