Choose a student or two in each class each day. When they walk in, act like they're your best friend you haven't see in a while. Ask them how their weekend was, how their day is going, basically talk about anything other than the math.
Why do we decorate all of our classroom walls? Take 10% of your walls for yourself and let the students decorate the other 90%. This way the walls of the classroom literally are "our" walls instead of "my" walls.
Pick a day of the week and choose some students to briefly share an interest, hobby, ambition, anything they would like you and their peers to know about them.
