Photo scavenger hunts are a great learning activity. We had to capture parallel lines, globe, circle, rectangle etc. I t was interesting how after a few minutes the world around me turned into shapes and patterns. I am looking forward to using this activity in the classroom. Digital cameras can be used to take photos of sets, colors, collections. Etc. I think this is something students will really enjoy. Watching slide shows of field trips or other class projects will be a nice summary and reinforcement of what the students learn.
