Clips about paper folding and lottery numbers inspire questions about exponential growth and probability.
Processes using linear measurement can be adapted to teach complex topics such as polynomial multiplication, rational exponents, and logarithms.
Jason Silverman, Gail L. Rosen and Steve Essinger
Use digital signal processing to capitalize on an exciting intersection of mathematics and popular culture.
Nicholas H. Wasserman
The practice of problem posing is as important to develop as problem solving. The resulting explorations can be mathematically rich.
Yee-Min Cha and Scott A. Brown
Students analyze items from the media to answer mathematical questions related to the article. Linear and exponential models for population growth are explored, and dimensional analysis is used.
Laura M. Crowley
A favorite lesson is presented by a teacher. This lesson involves student participation in planning post-secondary school financing. Compound interest and the present and future value formulas are the mathematical basis for the lesson.
Helen M. Doerr, Donna J. Meehan and AnnMarie H. O'Neil
Building on prior knowledge of slope, this approach helps students develop the ability to approximate and interpret rates of change and lays a conceptual foundation for calculus.
Edited by Randy F. Hall
Students analyze items from the media to answer related mathematical questions. The mathematics involved in this month's clips includes percent loss and gain, proportional reasoning, and the application of Kepler's laws, which involve exponential equations and regression.
Roberto López-Boada and Sandra Argüelles Daire
Students use elementary algebra concepts to solve trigonometric and logarithmic equations and systems.
Ryan Brydges and Kevin Webster
Students analyze items from the media to answer mathematical questions related to the article. Exponential growth is the topic of both clips this month.
