Below are a couple links from my talk at NCTM (National Council of Teachers of Mathematics — nctm.org) in Philadelphia on April 28, 2012.
A couple sample problems:
Cell Phone Plans — great for noticing & wondering:
What’s involved in understanding problems with a financial context?
- Examining the given information and asking: What do you notice? What do you wonder?
- Digging a littler deeper and asking: What information that’s given is useful? What given information or other information might help you make a decision? What else might we want to know?
Other resources, easily accessible and make for great conversations and problem solving opportunities/projects:
Cable Pricing Schemes
Cell Phone Pricing Schemes
Credit Card Offers
Apps and Applets that graph repayment plans
Interpreting Health Care Plans — look at HR websites to find information
Interpreting Retirement account options
Reading personal finance blogs (i.e., http://www.getrichslowly.org/blog/, http://www.bargaineering.com/, http://www.thesimpledollar.com/, and more) — blogs like this often talk about how to make personal finance decisions and weighing what’s important to you and/or your family and the trade-offs sometimes inherent in such decisions.
mathalicious.com has a great library of problems that tackle many of the concepts above, are connected to the common core and come with lesson plans. Here’s a blog post about their work that I wrote a while back.
