I want to buy a small digital clock for my classroom. I am looking for one that lays flat, or with a stand, like a calculator. I want to use it to monitor students' times in and out of class for extra bathroom breaks and library trips, etc. They will have to record their time out of class and the time they returned. Some of my students are out of my room a lot, and I am trying to make them more aware (as well as their parents!) of how much time they are spending on those "emergency" bathroom breaks and such. (My third graders couldn't just use the analog clock in the classroom, I'd never be able to be sure if the times were accurate. ha) A colleague has one in her classroom that says really good stuff on it and it was made for just this purpose. However, the only one I saw on their website was around $50 and I'm quite sure she didn't pay that much. I won't see her again until Monday, and I want to get one ordered. Does anyone know ANY company that sells these little clock/timers ?
