ABSTRACT
The bulletin board above titled Reported Ratios† can be one in a series named Numbers in the News. (Others in the series could be Famous Fractions and Informative Integers.) Each group of children can be asked to create a montage consisting of eight examples of ratios reported in newspapers, journals, or other periodicals. Have the groups cut out the advertisements, news reports, sports stories, and so forth and highlight the ratio. The class can discuss each group’s montage before it is posted on the bulletin board (e.g., What are the different ways ratios are verbally expressed or symbolically represented in each montage?). More advanced students can discuss whether the ratio describes a part-whole relationship (the size of a part compared to its whole), a part-part relationship (one part of a whole compared to another), or a rate (a measure compared to a different measure).
