How can you share this process with students? What would they learn from this? How could repurposing problems help them acquire more in-depth knowledge of mathematical modeling as a 21st century learning strategy?

Transforming the Old Into New.

Step 1. Select
Look through the materials and resources you use to teach mathematics, and select a problem or activity that lends itself to refurbishing through the use of mathematical modeling.

Step 2. Critique and Compose
Formally critique the problem in a brief paper with an eye toward giving it a 21^st century twist. For example: What’s good about the problem? How can it be repurposed to make it real world? How can mathematical modeling be incorporated? Does it lend itself to a career of interest?

Step 3. Modify and Describe
Modify the problem to increase the opportunities for mathematical modeling and application to real life. Compose a brief paper describing the problem’s transformation.

Step 4. Reflect
Respond in writing to these questions: How can you share this process with students? What would they learn from this? How could repurposing problems help them acquire more in-depth knowledge of mathematical modeling as a 21^st century learning strategy?

Step 5. Compile
In a final product, assemble the original and revised problems, the critique of the original problem, the description of the problem transformation, and the response to the reflection questions in a product of your choice appropriate for sharing with students and/or colleagues.
