I switched from Abeka and ACE to Math u See. I am so glad we did. I took them back to see what they missed. I was surprised that my 10yr old, then (9)went back to Beta. But at least I felt comfortable with pushing him threw quickly. My other son (8) is doing Gamma now and is almost finished. My other son (10) is finished with Delta. We will be probably be moving into Epsilon over the summer but at a slower pace. We will be doing other math games and a fraction pizza game. Just to reinforce what he is learning. :) We are also doing some "Family Math" for reinforcement.
I think Math u see was the best choice. If they are having problems i have them watch the video. Then, if they are having problems we sit down and try and find out what exactly the problem is. Most of the time it was something simple.
I would encourage you to use Math u See because they use all of their senses. If they are a visual they have the DVD, Kinetic they have the blocks, Audio, they have the skip count tape.
I would also buy the DVD on line. I purchased most of mine from E-bay. The Student manual you can buy from the company for $25. + Shipping. If you need the teachers manual those usually come with the DVD when you buy it. I never used mine with the younger grades but when you get into division or fractions it may come in handy for you . I just plan on selling mine with the DVD when we are done. :)
I bought the skip count tape and the munipulatives seperately. I only purchased the basic munipulatives set and we didn't use it that much. But my youngest may use it more. I also purchased the fraction overlays last year because knew we were going to stick with the Math u see program and I knew we would continue throughout high school with it and He will be using them this year. :)
I hope this helps. I just find that it seems like a great program. I also looked at Kathy Duffys website for the 100 best picks and that was one of hers. :) I highly recommend it and won't be changing this one either. :)
I hope this helps! Blessings!
