I checked with our library and they use Mango Languages for an online Spanish course, has anyone every heard of that? Also, I see that the Tell Me More is at a good price at http://www.homeschoolbuyersco-op.org/. Does anyone know if this is better than the others and would this be too hard for my 5th grader? Does it use the same concept at Rosetta Stone, I believe immersion? Anyone like Rosetta Stone better?
