FEATURES

Finger Math in Geometry
Don Warkentin
To gesture or not to gesture; is that really the question? Try out my technique in your geometry classrooms. You may be pleased to learn that the careful and conscious use of finger math will reinforce meaning for many of your mathematics students.

Algebra for Students with Learning Disabilities
Ruth Feigenbaum
The learning environment created in the special algebra classes, combined with the teaching strategies developed, has produced positive results for students with learning disabilities.

Consul, the Educated Monkey
Sidney Kolpas, Gary Massion
"Consul", the Educated Monkey, is an outstanding, practical example of a plane linkage. In learning why the monkey works the way it does, students are required to review many important concepts from plane geometry, algebra, and arithmetic. Making their own "monkey" linkage similar to Consul, which one of the authors has done with construction paper and paper fasteners, would give students additional, hands-on experience with many important mathematical concepts.

Traveling toward Proof
Timothy Craine, Rheta Rubenstein
We have found that the extended metaphor of Aristotle Airlines is extremely helpful in supporting students' construction of proofs. It fits well with both flow and two-column forms, and it acts as a stepping-stone to paragraph proofs, as well.

Messy Monk Mathematics: An NCTM Standards-Inspired Class
Larry Copes
A description of inquiry-based teaching and learning.

Using Financial Headlines and the Internet to Keep Statistics Classes Fresh
Marilyn Durkin
Stocks, market, and financial data, and their connection to mathematics.

A Geometry Solution from Multiple Perspectives
Phillip Nissen
It is perhaps informative for students to see that no one approach to geometry is the best. Students should be encouraged to try a variety of approaches when attempting a solution to any problem, experimenting and discussing which method is helping them find an answer. For some problems, students could develop a hybrid method, which would allow them to experience the creative aspects of mathematics.

Project Jacobean: A Mathematical Exploration of a Literary Era
Josi Binongo, M. Smith
In this investigation, differential calculus appears in a field where few would expect to see it: the study of literature, in particular, the attribution of an anonymous work.
