A Good Day For Math

I had a good day in math class today.  I substituted for a 5th grade class and I was able to use an Active Learning Energizer with the class who had been studying mean, median, and mode.  The purpose of the activity was to get the students to understand the difference between the mean, median, and mode.  Our materials included data sheets and pencils.  The students were paired up in groups of two and told to do as many sit-ups  as they could in one minute.  The partners recorded each others' scores.  Then, the groups of two were combined with another group of two to make a larger group of four.  Using a prepared form and the data from the situps, each group determined the mean, median, and mode of their data.  It took about 10 minutes and the students appeared glad to get a break from routine lecture.
