How many nurses does it take to support one doctor? A project-based activity asks learners to analyze state data to answer this question. Classes create polynomial functions from the data of doctors and nurses over a seven-year period. They then combine the models to create a rational function and provide a summary of their results in a technical memo.

Instructional Ideas

• Choose data from the states that fit the models of interest
• Post the video resources for pupils to use when needed

Classroom Considerations

• Expects a prior understanding of rational functions and ratio relationships

Pros

• Includes scaffolding resources for those not familiar with Excel 
• Notes provide ideas to adapt the project for different concepts

Cons

• Only includes data through 2008, making the analysis outdated
