This is a common question and concern for new home- schooling parents.home- schooling doe not mean your child never leaves the house or talks to other children. Nothing could be further from the truth! Homeschoolers are highly active, and share excursions,classes, events, playdates and sporting activities, just like kids at school do, in fact they often end up doing much more, and mix in different age groups, which has some amazing benefits for younger and older kids.

To register with your state it is free, some families decide to create their own learning plans, which costs nothing, while other families decide to buy a pre made curriculum. There is alot of free resources out there and alot of tailored curriculums to fit all budgets , you then have cost like books, pencils,printer ink ect. I home school ( natural/unschool ) - created my own learning plans for my 3 kids for free, i spend about $100 a year - on printer  ink -art supplies, and plastic sleeve folders, everything my children learn is from nature and living , eg cooking, surfing the web,nature, excursions.the list of free resources is never ending, the internet is filled with lots of free pintables, classes, youtube how to videos!  So the price really depends on your family, the style of education you choose to use and of course your budget
