Using Relay Races to Learn Time and Averages

This week we used relay races to teach about time and averages. For all grades the students discussed and put themselves on teams using the count off method. We discussed how this was dividing them. The students were given the jobs of timer, starter and finisher. All teams used a stopwatch. First and second graders logged in their journals their team time using minutes and seconds. For 3rd grade the students had to convert their time from minutes and seconds to seconds. 4th and 5th graders logged their team time and then divided by the number of racers to get the average time.
