We are using Math-U-See. I took Dd11, 6th grade, back to multiplication (gamma) and division (delta). She's already finished with the multiplication and will finish the division in a week or two. She still doesn't like math, but she can do it. It has been a huge help to us! As we started each book I gave her the unit tests as sort of a pre-test. We started at the point that she didn't pass the tests. I'm really hoping to get through a large portion of the epsilon book before ITBS. (I pulled her from PS due to incredibly low ITBS math computation scores.)
