There are so many resources available for free, or almost free.
Each of my boys really enjoy using their own IDs and passwords. The beginner lessons can be up to two hours (several smaller practice lessons inside each lesson), so be sure to read descriptions and break them into smaller chunks.
The free lessons from Hoffman Academy have been a huge blessing to our family. We started when the boys were in second grade and could read fluently. In the beginning units the parent might want to to sit with them during each video lesson and practice, but they are only ten minutes and we all look forward to watching the lesson video each week. I am amazed at how much the boys have learned through these lessons in just a short time.
OUR SCHEDULE-We watch a video every Monday, then practice each day afterward. The website has practice helps, and tentative practice schedules. Once got the hang of the routine, I typed a practice schedule with all their songs , practice games, and finger power exercises for the boys to practice more independently whenever we don't have a video.
We spend the very small amount they ask for printable materials & & practice MP3s ($20 for 20 lessons), and it is so worth it! If you sign up for an account, they send great deals via email, we bought Unit 2's material for only $12!
We finally purchased Rosetta Stone when it was on sale this Fall. But in between lessons, the boys have really enjoyed and learned a lot from the DUOLINGO app. It has voice recognition and several different languages. I don't think it can replace a full language curriculum, but good practice and supplement.
