Students analyze items from the media to answer mathematical questions related to the article. This month's clips examine why raindrops do not crush mosquitoes and feature an application of the Pythagorean theorem to baseball. The mathematics involved includes dimensional analysis, ratio and proportion, and the Pythagorean theorem.

Students analyze items from the media to answer mathematical questions related to the article. The first clip this month uses dimensional analysis and problem solving; the second involves fitting a sinusoid to global warming data.
Readers comment on published articles or offer their own mathematical ideas.
Students analyze a photograph to solve mathematical questions related to the images captured in the photograph. This month, the photographs are of a pyramid in Egypt, and students are asked to compute volume, slant height, and the ratio of the base of the pyramid to its height.
