This article focuses on observational assessment in student learning of mathematical concepts in two sixth grade classrooms. Many of the class activities involved algorithms and open-ended problems in which students worked in collaborative groups, pairs, or individually. (MM)

Combines mathematics, literature, and technology to help students discover exponentials. Includes details of several activities with teaching notes. (MM)

Argues that by celebrating the number pi with special mathematical activities we may be teaching the fundamental concept of the place-value structure of our decimal place system. Includes several examples to illustrate the argument. (MM)

Part of a series exploring how mathematics is used in the workplace. Software developers and statisticians record data of hockey games and players using statistics accessible to middle school students. (MM)

Students can form beautiful curves through a kinesthetic experience by using a dynamic geometry program. The examples included are parabolas, pursuit curves, spirals, and more. (MM)
