If your students are like mine, they often forget to write down the homework and are glued to their devices. Why not use their cell phone in a positive manner...text them homework reminders! Remind (formerly Remind 101) is a great communication tool that protects the teacher and student privacy while being connected. Once you, the teacher sign up, Remind issues you a "phone number". You can create a class group/code or you can do it by periods... It is also great for clubs and activities as well (I use it for Academic 
Decathlon too). Remind allows you to personalize your sign up code.  They have a very student friendly PDF to display on your projector or to email to parents and students. Students and parents can then sign up to receive text message or email reminders. You can now also upload files (great to include the homework PDF or other important documents). Another great feature of Remind is that you can schedule texts in advance. It is a great way to communicate with students and for student clubs to remain in contact with their members. They even have an app for teachers and students. Learn more here:
