Wish List for Classroom "Tools"

Hi,

I am a grade four teacher who has the opportunity to apply for a $300 grant for items that can be used in the classroom to enhance learning. The only real stipulation is that it can't be used for computer hardware. What would other teachers recommend? Is there one tool that you find really extends your student's learning experience or perhaps some subscriptions to websites that are valuable (our school already has a www.brainpop.com subscription)?

Thanks for any input!

Chris
