Teachers - how do you communicate with your students' parents?

[Wonderful1908]

I usually call or email. I know our district is moving towards a system where our lesson plans and homework our on the online, but unless a child is failing I rarely call, every blue moon I will call to say someone is really a great kid. I don't have the time anymore to do all that though, since we moved from 4 classes to 7. It sucks!
