Remind101 is a free service that allows teachers to safely send text messages to students and parents.
Teachers never see the students' or parents' phone numbers and the students and parents never see the teachers' phone number, helping to maintain privacy. Students and parents sign up by sending a text message or email instead of visiting a website. Teachers can have up to 10 classes and send messages to a class of students, or parents, or both. You can even schedule messages to occur in the future.
This is another tool that teachers can use to communicate with their students and parents and help remind them of upcoming due dates and events.
