My son is 5 and in Pre-K. Smart as a whip. But at this moment, I'm really trying not to get frustrated with my him and his homework. I was shown his class book and the kid looks like he knows what he's doing. The teachers say he is smart and quick and does his work. But he get's home and (forgive the term) "dumbs out". He can't think, he knows nothing and it's like...what's going on here???!!! *sigh* How do I deal with this??
