I have never felt comfortable with giving my phone number to students, but I know teachers that do. I knew one teacher that actually gave out her cell phone number! I worry that overbearing parents will call me all the time, or that students will read the directions on a HW assignment once and decide it's "too hard" and call me right away (during dinner, of course! :lol Do you give out your number? What's your experience been like? Do you have rules, such as, no calling after 9 pm or no calling the teacher without phoning a classmate first?
