I keep an information card on all of my students. I pre-print index cards on the computer requesting each students name, date of birth, address, home number, parents' work and cell phone numbers, the book numbers that they were issued and their email address. I punch all the cards and bind them with a ring. I keep them in my book bag so their information is available to me at school and at home. I just recently thought of pre-printing the information requests on the computer instead of having the kids do all the writing.
