I would not advise you to stay wide for most of the shots. You will regret it later in editing.
The people who hired you are looking to promote themselves to schools with this video. Your customer wants the schools to be engaged in their presentation, they need to draw them in to get hired, so that should be your motivation too. The closer you are to your subject the more your audience will identify with them and like them. So I would go with an array of medium to close shots if I was you.
This is about working with children, right? So get lot's of close ups of the children, their eyes, a smile, a raised hand, and of course lot's of interaction between the social worker and the children. Once children are engaged in some sort of activity they are so natural on camera, and that will make you look good.
If you are nervous about your shooting skills you should go out and practice. I like to practice at the Union Square Farmers Market here in New York. You have a lot of people that are busy shopping and most likely they won't mind to be videotaped. Also, they are not going to stay at a fruit stand until you have found your perfect shot, so it's a perfect way to train yourself to make rapid decisions and get a full array of shots withing a limited time.
And definitely use Mark's advice; you have the camera, so you are the boss!!!
It sounds like an exciting project, I wish you good luck with it.
