Reaction Time

Today, students used a strip of paper to calculate their reaction time.  One student would drop the paper without warning and the other person had to catch the paper with their fingers.  When students grabbed the sheet, there were numbers showing how quickly they reacted.  The goal of the lesson was to teach students about decimal values in the tenths and hundredth place while also practicing landmark data.  Once students had a lot of reaction time data for each hand, they calculated mean, mode, range, maximum, and minimum.  The kids noticed that each hand had different speeds and they had a chance to compare their data to the other students.
