Google Voice is a manageable solution because I am able to keep my personal number private, yet access student questions by voicemail or text with my home phone and computer. It is completely free and easy to use. You can personalize your number when available. I used the initials of our school name. Google Voice automatically transcribes your voicemails and you can have them emailed or sent to your phone for viewing. There is even an app for your phone.
Many of our students come from low income homes and do not have a parent at home that is able and/or willing to help them complete homework. I feel a moral obligation to do my best to help them. This is one way to reach out to them.
