Check in with your child's teacher on a regular basis to find out how he's doing. In particular, ask whether there's anything you can do at home to support what he's learning, and whether the teacher has noticed any changes in his academic performance or social relationships. In addition, find out what field trips are coming up and whether your child's teacher needs parent volunteers. Also, if your child's teacher sends out a regular newsletter, through e-mail or on paper, make sure you read it.
