     Find the group of cards titled Greeting cards.  How many different categories under Greeting cards?    Create a tally chart, listing each category.  You may create this on graph paper, flannel graphing chart, Excel spreadsheet, or other media.
     Use the tally chart information to create a bar graph that shows the total for each category.  The first Student to complete the BAR GRAPH gets to create the graph on the computer using EXCEL, with the teacher's assistance.  Each students gets to email their favorite card to a friend as they complete their graph.
