Evaluating Two Models

The model that students draw on the first page of Evaluating Two Models is likely to represent a single large landmass, though that is not absolutely necessary. They should represent that at least most of the landmass are touching or adjacent to each other in a way that matches according to shape. Their diagram should include labeled regions representing each of the 7 land masses, and at least 3 or 4 different kinds of data represented graphically or with labeling. Look for data to be located near and across boundaries where land masses are next to each other. For responses to the written assessment questions, see Teacher Key for Evaluating Two Models for details.

There are multiple elements in the written answers to the assessment questions that would provide an adequate answer. Not every element must be present in a student answer for a question to be answered sufficiently. See Teacher Key for Evaluating Two Models for scoring guidance. If students have not included any of the listed elements in their answer, list possible elements for them to consider. Also, provide feedback to students on their written work and models that calls out any missing elements in order to bring these to students’ attention.
