Still, as your children become older, I recommend getting them into consistent scheduling. It will make transition into college and the workplace much smoother. This worried me originally, but I found it needn't be a problem. There are many opportunities for social interaction, and more are becoming available all the time. With home education on the rise, you can probably find out about home school activities in your area through your umbrella school, which is the school you register under, or home school support network.
Some areas even offer co-ops with other home school parents.
Sports leagues, camps, field trips, proms, graduation ceremonies, teen banquets and retreats are becoming available. The only difference is you, the parent, know with whom your kids are socializing. The time I have teaching my children has been a rare and precious gift. Check into clubs and civic organizations. Don't forget your church, library, community theater, Scouts and 4-H programs.
