I finally caved and purchased the Rosetta Stone Homeschool version for Independent Study through Seton. Barnes and Noble had a great sale on Rosetta Stone this weekend (may still be on sale), I got it cheaper than the sale on the RS website.
So far, it is pretty amazing! I think this will give me a huge sense of relief that the kids can REALLY work on their own and learn the language. Just using a workbook and some time here and there from dad wasn't successful. That is what Seton offers. We would talk to Manuel on the phone. A lot.
The RS website says each level is one academic year, if you are wondering. I've already completed two lessons and may learn Spanish with my people. I just have to break my French habits.... I took French in high school and college and keep slipping in my Spanish pronunciations!
Submitted the Independent Study paperwork and we are ready to go.
