Provides weekly activities based on suggested activities from "Principles and Standards for School Mathematics." (KHR)

Invites students to try magic-number tricks and discover how and why they work. (Author)

Describes an activity in which students explore the mathematics used by urban planners by using a zoning chart of minimum and maximum building restrictions. (YDS)

Presents responses to the Mathematics of Motion problem which includes estimating the area of shapes on grid paper. (Author/YDS)

Features activities based on a theme that is usually associated with a particular month. (Author/YDS)

Describes how the student community can provide the context for integrating subjects and assessing student knowledge about data collection and analysis. Discusses the change of a teacher's practice through her reflections upon student learning and reform documents. (YDS)

Presents an overview of the 6-8 Standards and their rationale. Demonstrates the need for a cohesive mathematics curriculum. (YDS)

Describes student solutions to a "Food for Thought" problem using different strategies. (YDS)

Poses a problem in which readers are asked to determine which pentomino pieces will form a square. (YDS)

Presents student solutions to a problem using different strategies that focus on kitchen geometry. (YDS)

Presents solutions to the Have a Heart problem that appeared in the February 2002 issue of this journal. (Author/NB)

Presents the Shape Search problem to develop student visualization. Focuses attention on the National Council of Teachers of Mathematics (NCTM) Geometry Standard. (Author/NB)

A beginning solution and generalization are given to a problem on area and perimeter presented in a previous article. Various figures are used to illustrate how posing problems and identifying increasingly general methods promotes problem-solving maturity. (MNS)

Presents reasons for students' use of calculators in math class and techniques for encouraging their optimal use. Many educators suggest that calculators free students from concentration on computation and enable them to concentrate on problem solving. The article includes product information. (SM)

Describes three simple games that do not involve numbers and that can be used to teach children problem-solving strategies and math skills. The games are Tick-Tack-Toe; Jest, a game that uses a blocking strategy; and Nim, a game that uses a capturing strategy. All three games force students to plan ahead and calculate possible outcomes using…
