I have never been able to figure this out. Some teachers seem to appreciate some information, and others don't seem interested at all. I would probably write an email with a paragraph summary and tell them if they would like to talk more or would like more info or suggestions on things that you've found that help, to let you know (and put your contact info). If child has a 504 or IEP, that can help because then there is at least something in writing that you can refer to, and with an IEP at least, someone is in charge of making sure it is implemented and communicating w/ the teachers. I have been trying to direct communications to IEP manager now that children are getting older and multiple teachers are involved w/ them. Many teachers seem to take too much communication directly from parents as criticism, unfortunately. I try to head this off by writing the email when school starts rather than waiting for something to go wrong.
