I have always thought my boys were brilliant. I once spoke to a homeschooling mom who runs a curriculum business which is great, she also has 3 grown boys. I was describing my oldest to her and how difficult I found it to teach him because he was so fast. She told me many helpful things because she had one son who was very similar, but what stuck in my head the most was this statement. "They make wonderful adults."
My oldest is now 7 and absorbs many things, but rarely what I want him to learn. His best subject is not even a subject. He is a geogprahy whiz thanks to our SmartGlobe. If you don't have one for your kids you should. It is really amazing.
When DH's youngest brother, who is in medical school, visited a few months ago he was amazed at the oldest's ability to locate places and asked him to do it over and over again. Early one morning they were competing with one of the games where you find places as fast as you can in a certain amount of time. The 7 year old beat the med student. Good thing he just needs to know anatomy.
In fact he asked my son so often to repeat things from the globe he was finally told, "You really need to get a SmartGlobe". I love my kids! They can always make me laugh.
