In this activity, students are shown three clocks, one with a starting time, one an ending time, and the third has the current time. At first the current time is the same as the start time and the students advance the current time by either one hour, five minutes, or one minute until they get to the end time. The applet keeps track of how much total time has elapsed. The student can also switch to guess mode where they are given a start time and end time and have to guess the amount of elapsed time between them. This activity allows students to practice reading clocks and finding how much time has elapsed between two times. This activity includes supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet.
