My latest contribution to the New York Times Learning Network is a math lesson that explores the mathematics of the so-called Fiscal Cliff.
Look Before You Leap! Understanding the Mathematics of the Fiscal Cliff
In this lesson, students explore the quantitative consequences of the expiration of policies like the Bush Era Tax Cuts and the Payroll Tax by calculating income tax differences for individuals across income levels, and putting those numbers in context.
Students are also directed to consider the situation from the perspective of the government by approximating tax-revenue increases and investigating the consequences of discretionary spending cuts.
