Today Richard and I studied a data set of students and the number of cookies they sold. We first interpreted the tally marks and identified what quantity they represented. Then we used the scale that a dark circle represents 2 cookies and a light circle represents 1 cookie. Richard used that scale to model the number of cookies each student sold. Then he answered questions like, "Who sold the most cookies?", "How many more cookies did Tyler sell than Tom?" Lastly, we created a bar graph to represent the number of cookies each student sold.
