Couple weeks ago my son came to me and told me he didn't want to use TT anymore. I think it was too abstract. He couldn't experiment with math on the computer. I downloaded a sample lesson and my son loved it. We have started the first lesson and he really likes it and using all the manipulatives. He is a very visual thinker. My younger son loves it as well. Unfortunately he still likes TT and is having a hard time choosing which one he wants to use. He loves them both. I just wanted to share our good fortune. I also like how Math u see really compliments our math journals that we are doing.
Have you ever changed anything late in the year?
