For the past 26 years, PNC Bank has produced a summary of the cost of all the gifts involved in the song "The Twelve Days of Christmas." This can be used as an engaging way of presenting economics concepts.

For 2009, PNC has enlisted a group of children to help deliver the information. The updated site includes a video presentation, an interactive chart, and fun games and activities that can be used for:

• A discussion on inflation
• A math lesson about reading charts
• A history lesson on wages for skilled and unskilled workers

New this year: get fun facts and trivia about each of the gifts in the "Twelve Days of Christmas."

Twelve Days of Math Lessons

Eric O'Brien, of the Shore Road School, Bellmore, NY, has taken this carol to his classroom, and started a discussion on the middle school (grades 5-8) discussion group of the Association of Math Teachers of New York State, hosted at the Math Forum. (Eric serves as Middle School Representative to AMTNYS's board.) Discussants have explored financial and number- theoretical aspects of the scenario. Read their views and share your own using the link above--free registration is required to participate in the discussion. Look for the threads beginning "Tis the Season."

The thread resulting from Eric's initial post is here:
