3. What is Elapsed Time? Time that has passed between events that occur Remember:  60 minutes = 1 hour  Short hand tells the hour  Long hand tells the minutes

4. Example Problem from the Story At 5:00 a.m. the sun came up and the grouchy ladybug met the friendly ladybug. At 8:00 a.m. the grouchy ladybug met a praying mantis. How much time passed between when the grouchy ladybug met the friendly ladybug and when it met the praying mantis?

5. Strategy for Elapsed Time You can use a number line to help you figure out how much time has passed between two events. Step 1: Locate the time you begin with. (5:00 a.m.) Step 2: Count by ones to the time of the next event. (8:00 a.m.) Step 3: Count the number of jumps you made, and that is the elapsed time. 3 hours 1 2 3
