I do not home school. My oldest son has been going to a Montessori school that I'm very happy with. I think he's smart and ahead, but I don't think he is gifted to the level of a bunch of your kids. He may only be ahead because I was home with him and I was bored so I taught him lots of stuff. I may be projecting my perceptions of my own averageness on him though.
Our area has public schools that everyone loves. I read the objectives for 1st, 2nd and 3rd grade and if they are accomplishing those things, I can see why people would think they are great, but they are way behind where he is.
His Montessori school's curriculum is ahead about 1 1/2 years to 2 years to the public school and my son was the best reader in his 3-6 year old group last year. He was reading Magic Treehouse books in the first week of kindergarten. When I read the objectives of the public school he wouldn't be exposed to anything new until the second grade material, although most of that isn't new to him either. Most of the 3rd grade stuff would be new.
He does need work on writing and spelling and I think either school would be good for that. He is very social so he would love the public school just as much as the Montessori school. He'll just be happy to be socializing with a bunch of other kids.
I thought I would talk my husband out of it by now, but he wants to save the money and has dug his heels in.
I guess I want to feel better about it somehow. Maybe its good enough that he only learns spelling and writing and by third grade there is a gifted program and he'll have new stuff then.
My brother and mother were actually gifted. I don't know my mother's IQ but brother's was, I think, around 140. I don't know which category that is. Public school was OK for my mom. They put her ahead one year and wanted to put her ahead two years but her mother wouldn't allow it. Public school was awful for my brother. They put him ahead one year which is probably bad for a boy for non academic reasons. He didn't try at all. He knew he was smarter than all the teachers and just aced tests and did no work at all. He's spent most of his life as a cook at a chain restaurant.
