In this interactive activity, students will be led through steps to find elapsed time in a variety of math problems. There are teaching activities as well as practice activities available. A handout that describes strategies taught during the interactive is available to be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.
Students are asked to estimate time and numbers of objects in situations in which counting is not feasible or necessary. This CYBERCHASE activity is motivated by two sections of a Cyberchase episode: 1) In the For Real section, Harry is waiting in line for tickets and trying to estimate whether he has enough time to buy his tickets before the booth closes (based on the length of the line and the rate at which it is moving); and 2) In the animated portion of the same episode, Inez estimates whether she has enough jelly beans to decorate all of the cookies in a batch she is preparing.
