This is the letter that I give to incoming parents at our start of the school year social, which takes place the week before school begins. It provides general information about our class, and gives parents an idea of what to expect on the first day of school.
On the first day of school I send home a class handbook with details about class policies and procedures (I'll post a copy of that soon). I also include a copy of this welcome letter with the handbook to ensure that parents who missed the social receive a copy. I think this letter helps set a nice tone for the school year.
