My 10 year old had to write a report about Thurgood Marshall. I have to admit that I didn't know much about him. In case you don't know about him, he was the lawyer who won the "Brown Vs. The Board of Education" case that enabled the blacks to attend public school with whites. He eventually became a Supreme court judge himself.
Thurgood's name was actually Thoroughgood, but as a child he didn't like writing that out, so shortened his name. His father used a very interesting punishment for him when he was bad. He had him copy the Constitution. The intriguing thing about this is that it actually developed in him an interest in the Constitution, and the law, and spurred him to become a lawyer.
I have heard of those who have had their children memorize bible passages as punishment. As I thought about Thurgood Marshall copying the Constitution, I realized that I may have missed the boat in punishing my children as they were growing up.
