Instructional Ideas

• Have students refrain from asking about why the word problem is modeled by a specific type of variation

Classroom Considerations

• Requires the class to be familiar with the types of variation
• Uses access to computers to research real-world examples of the types of variation

Pros

• Includes a sample benchmark set of responses
• Contains a rubric to score the task

Cons

• None
