If we can educate our kids at home why do we need to send them at school?
If socialization is a problem in homeschooling, there are many solutions to that ;-)
The education you give your kids at home are quite different from that of schools. The time spent with your kids at home, cannot be compared with the time teachers spend with your kids and impacting knowledge into them. The school, unlike your home have what is called curriculum.
You can literally download any school's curriculum on the internet and just cover the topics with your kids. Heck, you might even learn something yourself in the process.
