Answer truthfully. Don't lie like others mentioned. I had the exact situation and I wrote the following....
EXPERIENCE
Home School Teacher
*Full responsibility for educating 3 children.
*Conducted daily classes, all subjects. Children now fully integrated into charter schools.
If people don't want to hire you because you took the higher road and not only were a full time mom, but home schooled them - then the hell with them. They don't get it, and never will. Don't work for people that try to minimize the huge job you had. Unfortunately 10% of our population is unemployed because of Obama. So it will be difficult trying to get a job - so you may have to lower your expectations on the type of job. Many people with college degrees are now not getting jobs in their field but minimum wage paying jobs anywhere they can get one. If you are desperate for a job, take any job that hires you, get a little experience that you can put on a newer resume and if you dislike that job, look again elsewhere for something more appealing.
Good luck on your search.
