Ideas/resources for "green" back-to-school tips?

I work for an environmental group and we're putting together some green tips for back-to-school, i.e. buy recycled paper, use re-usable lunch bags or lunch boxes, cut down on pre-packaged lunch foods, etc. Does any of you moms or dads out there have any helpful tips (or links, resources, etc) of your own? Have you found any great school supplies that are environmentally-friendly? Thanks.
