I know someone who's kid had a problem in the first grade. Pulled him out. He was a carpenter. Taught the boy to read, write, do math, fractions, and measurements it 8ths, 16ths, etc. School board finally found out by the time he was 10. The tested him, and put him in the 4th grade. Dad took him to work with him every day, had him measuring wood, figuring lumber, etc. School board finally found out by the time he was 10. The tested him, and put him in the 4th grade, and the kid didn't miss a beat. Parents can teach kids in the early years quite well. They only need school for higher level math, expanding their vocabulary, and more in depth study of science and history. I home schooled the first 6 years on my kids. Have 5 out of 7 in college now. They are having to work their way through, so sometimes it is part time and a slow go for them. One is married, one didn't want to go to college, but is learning heating/air conditioning.
