In this skill, students demonstrate the ability to analyze representations.
To develop an understanding of this concept, students will need to be introduced to several different types of representations of the same place that communicate different types of information. Facilitate a class discussion to help students identify the characteristics of each representation, its advantages, its disadvantages, and the specific purpose for which it is most appropriate. This is an abstract concept and students will need a number of concrete examples to help them understand that the same place can be represented in many different ways and that different representations serve different purposes.
Students will be able to identify varied representations of the same place. They will be able to describe the advantages and disadvantages of each representation and the specific purpose for which each representation is most appropriate.
