Don't be a know it all. I know you're not because you are asking this question.

Seriously, though, it's hard for people to come with questions if a person seems like they know everything. Be careful not to be judgmental. Approach working with them as "let's figure this out together" and keep the focus on helping the children.
One idea that I loved was when someone in a role like yours started the year with scheduling a lesson in everyone's classroom during the first two weeks of school. This is such a crazy, busy time and was very much appreciated. It gave her a chance to get to know each classroom of kids, too.
