If you are able to acquire an old digital camera, I highly recommend it for the classroom, or for home. Spend a few dollars at Goodwill and don't get too attached, though - technology changes and cameras can end up in sticky (or wet, or temper tantrum) situations. I've acquired a few over the years, and the photos above were taken with a 3.2 megapixel camera. Skip fancy, skip "made for kids" - and let your children use the real tool. You'll love the photos they take!
