Directions are given for making a model of a three-dimensional coordinate graph. (DT)

Highlights a mathematics program for gifted students (ages 6-8) in Beijing. Different components of the program are described, including using audiovisual geometry, emphasizing the combination of shape and number, stimulating imagination, applying the discovery method, and using the search-out model. Provides sample math problems. (CR)

Presents a plan involving routine classroom tasks to integrate mathematics with cooperative learning teams in a second-grade class. Explains the process and describes some of the ways in which the activities are used to provide an opportunity for the team and the student to apply mathematics. Concludes that cooperative learning has many merits.…

Describes an episode involving conditional statements and the notion of logical equivalence that occurred in a 10th-grade college-preparatory geometry class. Illustrates some of the confusion that can arise in connection with this topic, for both students and teachers. (ASK)

Describes a study in which Australian children aged 5-8 years old (N=70) were presented with a range of measurement tasks to determine the strategies and devices that they would choose to use to measure length. Results are in conflict with the normal curriculum sequence. Contains 30 references. (DDR)

Comments on Gregory Trandel's article that explores two teaching strategies using geometry and algebra to demonstrate the equivalence between two methods of measuring excess burden. States that for students with limited mathematics skills, measuring excess burden can be expressed algebraically using a simple formula (excess burden…

Examines values that seven secondary geometry teachers placed on their participation in a school-based study group and the organizational structure and the impact of that structure on teachers' continued participation in the study group. Shows that the teachers were supported in building community and relationships, making connections across…

Presents a project that addresses several components of the Algebra and Communication Standards for Grades 9-12 presented in Principles and Standards for School Mathematics (NCTM, 2000). Describes doing mathematical modeling and using the language of mathematics to express a recursive relationship in the perimeter and area of the Koch snowflake.…

Presents a geometric problem and illustrates four different ways to solve it: (1) a synthetic approach; (2) a coordinate approach; (3) a vector approach; and (4) a transformation approach. (KHR)

Presents ways of making mathematics come alive for students including inviting historical mathematicians into the classroom. Suggests that costumes and drama add special appeal to looking at the history of mathematics. (KHR)

Presents a map-projection activity that combines mathematics and geography through investigating the proportion of land and water that covers the earth. Focuses on helping students become familiar with characteristics of different projections or representations of the world while estimating and graphing and encouraging them to investigate the…

Describes a group project that involves geometry and falls into an area of mathematics known as operations research, which is crucial to making decisions in business and industry. Includes problem statements and project assessment guidelines and illustrates solutions. (KHR)

Addresses the role that mathematical definitions can play in the middle grades mathematics classroom and focuses on the concept of angle as it was introduced to 6th grade students. Describes a traditional approach and an alternative approach to teaching the concept of angle. Illustrates students' concept images of angle. (KHR)

Describes an activity inspired by the work of Nobel Prize winner Dorothy Crowfoot Hodgkin involving multilink blocks that helps students develop three-dimensional spatial skills. (YDS)

Describes a lesson plan using a chambered nautilus to connect geometry and poetry which can be easily adapted to a wide range of levels. (YDS)
