Check out Powerhomeschool, Khan Academy, Dr. Binox, Lotty Learns. There's lots of available resources. We home school 3 kids for less then 1k a year. There's also a tax rebate for up to $1200 per kid for home schooled kids where we live.
Ron Paul also has a home school program that we're looking into for our eldest. It's 550 a year for one student and 1150 for three students.
Yeah the issue is having one parent home during the daytime hours to accomplish it. We could work opposite shifts, but there is a lot of value to being together as a family on a nightly basis. For now the plan is just to do parenting at 250%, and try to nip bad behavior and the side effects of terrible parenting of other children in the butt.
but really... if you guys don't deal with many young adults, go out of you way to engage in a conversation with them. Between online gaming, technology, and just piss poor parenting... I am surprised some of them are able to even dress them self. They sure as hell cant hold a conversation.
If you let your children of any age spend more than 1 hour on a phone or tablet on a daily basis... shame on you.
