I read somewhere about a teacher who used a cheap camera in her room so the kids could take pics of their tasks during stations. I looked all around for a 'cheap' digital camera. I finally found one! It was fifteen bucks at Meijer. It's a very simple camera, but that's just what I needed for my munchkins to use. I just hang it at the station and they have someone take a pic of them when they finish a task. I told them that I wanted them to 'prove it' so that I know how hard they are working.
