We are using La Clase Divertida and the kids really like it, and I am learning too. You dont have to do the workbook, just watch the videos if you want to. He is big on family participation, which I like. It was filmed a while ago, and nothing flashy but we are learning and the kids ask to watch it daily.
We have Roseta Stone, but I won’t start that until 3rd or 4th grade.
