Homebound vs. Homeschool

My son is going to be homebound educated for the remainder of the school year. He has been at home since January. I have had questions about homebound teaching vs homeschool teaching. The difference is huge -- with homebound, we are provided with a tutor for 5 hours per week, plus that person can act as a liaison between home and school. In addition, the lessons that are to be taught at home are provided by the school. Hope this helps with the confusion.
