(These examples are shown on plastic disposable plates. I just love this affordable option for student white boards! Just use a piece of felt or a tissue to wipe them clean. In class, we often also use white boards and chart paper when showing our examples.) Students always seem to struggle with elapsed time. It’s a hard concept for them to wrap their brains around because it is so abstract. When I taught third grade, I even found some students who have severe deficits in the basics of telling time. These students are just now mastering time to the minute, so I knew they would really struggle with elapsed time. This great way of mapping out elapsed time works like a charm. I wish I had learned it this way in school, because it just seems so obvious! Hop over to The Primary Pack to see the steps in action!
