Homeschooling 2 kids - 2nd and 3rd graders. Many reasons for us...religious, public school indoctrination of socialism/not enough time spent on important info/too much wasted time/bullying/drugs/alcohol, etc. The public school only wants parents involved in THEIR agenda and if parents rock the boat or don't want to go along with their approach, the parents are labeled and ridiculed and it's now that you find out that they want you to be sheeple there (don't question them, just follow the crowd.)
I have a 25 yr old also who attended public school. After the bullying in the 10th grade, I attempted to homeschool her but I wasn't dedicated enough and we ended up putting her in the "night school." BIg mistake. I knew as soon as we had my 9yr old that we'd never put her in public school.
Since we are still early elementary, we don't use any curriculum. We put our own curriculum together during the summer - what we'd teach each week/month. We buy any kind of books related to science, math, social studies that we can find at the library sales and goodwill. I LOVE...LOVE...LOVE to find books for 25 cents!
