So, an amazing teacher next to me used a card similar to these next to her phone on a ring to access them quickly. You copy them on cardstock and cut in half. Then put them on a ring in the upper left corner and keep them close by so when you need to call a parent for any reason it is easily accessible. There is a documentation form on the back to keep short quick notes of your contact. I loved this idea and couldn't wait to start using it!!
I hope you enjoy!!
