Remind101. Remind101 is a safe way for teachers to text message students and parents about important classroom events without the need to give out their own number and without the need to get their students' numbers. Teachers create their account at the Remind101 website and they will get a special phone number and code that they give to their students. Students text that code to the given phone number and will be enrolled in that teacher's Remind101 class. So now whenever a teacher sends a message to that class, anyone enrolled will receive it. The app only allows for one way texting: from teacher to class and not student to teacher. Remind101 apps are available for both iPhone and Android in their respective app stores. And it's FREE!!
