Thanks, DomanMom! I enjoyed reading your review. I, too, was looking for a math program that I could use after Doman Math and I was glad to have come across Dr. Jones' Matrix Math. We started the program a few weeks ago but, as my daughter is only 2, I don't expect to fly through the program as fast as Hunter did. It's great to hear how he is excelling in it! Please do keep us updated on his progress through the next levels.
