This 3 page document includes a letter to parents which states the purpose of the sign up form and reminder cards. It is intended to be available during Open House to schedule beginning of the year conferences held after the first two weeks of school to address minor questions and issues. It can be modified to fit your needs.
I have the sign up sheet and reminder cards ready for parents at open house with other materials and information they need.
