I think this Parent Contact Form would be very helpful in keeping track of which parents you have contacted and how often. It is important to make notes on what you discussed and this is one way to keep everything in the same place.
TEACHER TIP: I like to laminate cards, hole punch and attach onto a metal ring. Keeps student information at your fingertips throughout the year. Perfect for emergencies, field trips or quick contact information. Can hang on a hook in your room.
TA: Communication Log for students to fill out and attach in folders. Use these forms to document both positive and negative behaviors. Make it a goal to make parent contact at least once per semester for positive interaction.
