What sort of supplies do the local schools appreciate?

Hello - I'll be visiting in about 10 days and am considering bringing an extra suitcase of some random office supplies I've been noticing around my company. But I want to make sure it would be appreciated. For example, a ream of copy paper, various canvas tote bags that everyone seems to collect from the various conferences we attend (school book bags maybe?). Branded pens, pads of note paper, post-its, even stress balls that companies give out at trade shows. It all seems to go to waste here in the States and I'd love to be able to see it put it to use. Would the schools use it?

Many thanks.
