How much further did student A jump than student B?
Use spatial comparisons to make an estimate of the difference.
Use paperclips to iterate the distance of both jumps from the start point to the end point.
or
Use paperclips to iterate the distance of the longest jump first and then remove and use the same paperclips to iterate the distance of the shortest jump, noting how many are not used.
Provide students with the measurement of the paperclips in inches to determine the difference in the two distances.
