I have parents fill this out at the beginning of the school year so that I know the best way to contact them throughout the school year. I also added a log to keep track of parent communication. This is especially helpful if there are consistent concerns or a long term sub.
Parent Communication Log- Don't really need one this elementary, but my goal this year is to contact every parent at least once per semester... especially for the students who are doing great or are showing improvement! (:
