  • Compare the totals from different groups.
  • Have everyone do the task again with their other hand and compare everyone’s right hand total against everyone’s’ left hand total.
  • Have students line up, on a number line, relative to their data point. Or Put the data in numerical order on a number line.
  • Have students put their initials on a sticky dot and place it (relative to their data point) on a grid to create a class graph for the information collected.
  • Have students determine the mean, median, and mode and explain how each relates to the rest of the data points.
  • Make a box and whisker plots or stem and leaf plots for the data and explain how each relates to the rest of the data points.
