One of the things I ask the parents of my new students to do is to write a letter to their student. I give them the forms before school starts at an informational meeting and they take a minute to write the letter and stick it in their child’s desk. The kids are always excited about the letters on the first day. Some even share the letters with their classmates if they choose to. I then collect the letters after they read them and give them back to the students on the last day of school.
Attached is the form I use. It is free to print!
