All About Sharks introduces the use of two marked dimensions (horizontal and vertical scales), effectively turning value bar comparisons and line plots into more easily readable graphs. The scales are also extended to include fractions and scaled data. Students explore and graph the lengths and lifespans of a variety of sharks, measure their teeth, and work with real data sets from an environmental study near the Great Barrier Reef. This unit should be used at the end of the year, after Building Benches has been used (or after landmark fractions have been introduced).
