As a parent and assistant in the public schools I find it very helpful when a teacher takes the time to send out a letter about the upcoming school year and information about themselves. Two years ago when my son started school he was very anxious all summer about going. He has a spectrum disorder PDD and is going for testing this summer to determine if he has Asberger's Disease.
When his teacher sent a letter home to the parents and the students, she also included a small handmade book titled "Let's Get to Know Each Other". She took photos of all the people who would be working with them, such as the librarian, principal, vice-principal, art teacher and others. I thought it was a great idea and she said "the book really was not that difficult to do and took less time than she thought".
In her letter she included personal information about herself, what she expects from her students and what students as well as parents should expect from any educator. Confidentiality about her students, respect of personal and cultural views, that each student is unique and should be valued for their uniqueness. That she has a dedicated email address for her parents to send in comments or questions to. If it is something that cannot wait until the following school day to call her voice mail at the school and mark the call urgent.
She also included that she was a big Red Sox Fan, blue is her favorite color and that oranges are her favorite fruit. She also let the students know she has a grown son that lives in Washington D.C. and that her husband would from time to time be helping out as a volunteer in the classroom.
I cannot tell you how much this helped his anxiety and mine. He actually rode the bus to school the very first day, because the book and letter made him feel much more comfortable. I know teachers spent a great deal of time outside of school working on lesson plans, grading papers, parent teacher confrences, IEP meetings and the list could go on as you well know. If you can find the time to put together a small book with photos, a brief description of the teacher(s) who will be working with them, it benefits everyone involved.
Even if children attend a school for three years, there is usually someone they don't know who they will be working with for the first time this year. My son and I both have no idea what his new teacher looks like. We have seven or eight second grade classrooms in one school. It is even hard for me to remember who everyone is, let alone what they teach or do in a school with so many classrooms.
I wish you luck, and think that it is wonderful that you are taking the time to do this for both the parents and the students. They are lucky to have such a caring educator. Enjoy the summer!
