The computer tools for interactive mathematical activity (TIMA) were designed to provide children a medium in which they could enact the mathematical operations of unitizing, uniting, fragmenting, segmenting, partitioning, replicating, iterating and measuring. TIMA were developed in the context of a constructivist teaching experiment focused on…

Discusses a method that uses spreadsheets to calculate the exact distribution of the sum of two or more discrete random variables with arbitrary distributions. Demonstrates how this method can be used to investigate several problems that would be found interesting at the elementary level. (Author/ASK)

Explores ways to help children make connections between whole-number multiplication and their notion of a fraction. Illustrates an approach to constructing fraction concepts that builds on children's whole-number knowledge using specially designed computer tools. (KHR)

Analyzes mathematics software programs to find engaging and easy-to-use software for integration into the elementary school mathematics curriculum. Discusses criteria for judging good software and useful classroom implementation. (KHR)

States that thinking about numerical procedures starts in the elementary grades and continues in successive grades until students can eventually express and reflect on the procedures using algebraic symbolism. Outlines how such thinking can progress to algebraic reasoning. Illustrates how computers can be used to promote this progression through…

Introduces a course using mPowerNet to develop course material by using computers to teach numeracy. Presents the guiding principles of the course, mathematics material, course material, and course guidance. (ASK)

Describes an after-school mathematics enrichment program in which children can freely experiment and play with mathematics and presents research observations. Offers some recommendations to teachers for implementing the program ideas in their classrooms. Contains 18 references. (ASK)

Investigates uses of interactive geometry software to enhance students' understanding and reasoning about two-dimensional shapes. Describes basic principles that underlie high-quality geometry instruction. Presents examples that illustrate how appropriate use of dynamic software can enhance students' geometric reasoning. (KHR)

Uses three computer software programs to help students develop algebraic reasoning. Programs include spreadsheets, Logo programming language, and Teasers by Tobbs. (ASK)

Highlights mathematical developments of the 20th century. Provides a brief summary that hints at the flavor of recent mathematical developments. Presents stories that can add life to school mathematics and encourage students to join in the fun. (Contains 29 references.) (ASK)

Describes a teacher's experiences developing and implementing a three-week interdisciplinary unit for fourth grade students that revolves around the Alaskan Iditarod sled dog race. Students read about the race history, figure out a racing budget, learn about animal breeding and care, and follow the actual progress of the racing teams via Internet…

A collection of articles from the journals "Arithmetic Teacher" and "Teaching Children Mathematics" provide ideas for the instruction and use of teacher-made instructional aids. Guidelines used to select articles for this collection called for the articles to have a clear purpose and be related to a contemporary topic in the elementary school…

Presents a collection of computer programs for teaching elementary and middle school mathematics. At the primary level, programs teach students skip counting, measurement, graphs, number patterns, place value, addition, and subtraction. An action game for the upper elementary level teaches mental math, geometry, statistics, addition,…
