Print this document on 4x6 notecards (2-sided print) one for each student, punch a hole in the top corner and use a binder ring to hold them all together. The front has all of the contact info and the back has a log to keep track of all contacts made. You have parent contact information right at your fingertips. For added security, I have provided multiple "cover page" options so that the front card is not exposed to wandering eyes.
There are 26 different cover pages to choose from that include different font choices and class periods.
I have included detailed directions for printing.
8.21.15 update: I have a added a contact card that has Guardian #1 and Guardian #2 instead of Mom and Dad (also in Spanish).
