In-class exercise for visual aids
Have the students work in groups to create a simple visual aid for a set of statistics. Any easy-to-understand set of numbers will work — I used the season stats for the quarterbacks for the local NFL team. Challenge the groups to find the clearest way to present those statistics in visual form. Share their results with the class and talk about strengths and weaknesses of each option.
This idea could be further developed and given as a written assignment as well, perhaps requiring computer-generated visuals.
