I print these on cardstock, cut them into fourths, and put them on a ring. I keep these right on my mini-fridge behind my desk so I can contact parents easily and quickly. On the cards I have their legal guardians and their second contact. I have addresses, phones, and cell phones for the people listed as contacts for each student. That way I can just keep on calling if the first contact does not answer. They are also so handy to throw in my bag for a field trip! Editable and customizable
