Ordering Events by Duration

In math the students have been learning how to order events by duration. They often think that just because you do something ten times it must take longer than something that you do five times no matter what. We have been learning that you have to think about each task and how long it takes to do it just once. Then you have to think about how many times you do it. For example, it takes them less time to read their weekly poem five times than it does to read their guided reading book one time. At the conclusion of our lessons, the students illustrated three events, or tasks, from their school day and ordered them from the least time taken to the most time taken. They then wrote comparison sentences about the events' durations.
