My son was grade-skipped from K to 2. He is now in fourth. Recently he had his 9th birthday party at a laser tag place. The place was a half hour drive from the school. I picked up my son and three other boys. Remember this is fourth grade - the boys - not my son(although he eagerly listened and asked questions) - discussed among other things - The movies "Year One", "Austin Powers" and "Spinal Tap". The discussions were all related to the sexual content in a very graphic way. I put a stop to that conversation and the new one began with which girls in their class were "hot". Naturally I put a halt on the topic. This is fourth grade! Oh and a girl in his class told him that when girls get older they "pee blood".
What happens in another two or three grades...sigh........
I am all for grade skips academically but I wish there was a solution that allowed them to be with people that were both age AND ability peers.
