Well, if you can make the kids happy and they're learning something you'll be everybody's favorite teacher. Talk to them by name like you know each one of them personally and mention and little identifying habits to make them feel noticed and included, like you're Mr. Captain Obvious. You'll be fine because that age is really into letting an adult be cool (friendly) if they act like they are. Just off the top of my head because I'm not a school-aged parent yet, just what I remember from that age plus I have nephews that are around that age. The teachers I remember that acted like that were like a fresh oasis in the day for everybody.
