App: Remind

Do you want to get in touch with parents or talk to your teenage students via text but don't want them to have your cell phone number? Remind is the solution for you.
It's a free and safe communication tool that helps teachers connect with students and parents. 

Just sign up, create a class, add up your students or parents and start messaging! They will receive it as a text message or an email. You can also attach documents or send voice messages. In case you have kids groups, it's a great way to share with parents what kids have been doing in class.
