The problem investigated was the analysis of a complex figure by identifying simpler figures embedded in it. The primary goal was to determine the level of sophistication of analysis employed by children in the primary grades; a secondary goal was to determine if students could be led to expand their analyses. Drawings and problems were prepared…

Four activities encouraging the discovery of geometric relationships involving simple polygons are described. (JT)

Describes a unit introducing fourth graders to the metric system. (SP)

The use of games in retraining skills with basic multiplication facts was studied in elementary grades. The games were effective in retraining skills. Pretesting had no effect. (MP)

Four activities concerning addition and subtraction are described. They range in appropriate grade level from K-2 (crossing out objects) to 6-8 (solving decimal inequalities). Masters for worksheets are provided. (SD)

The National Science Foundation (NSF) has supported a wide variety of teacher enhancement projects in order to identify and explore strategies that are effective in bringing genuine, long-term teacher change, and, ultimately, long-term systemic change in schools. In November 1994, with funding provided from NSF (Grant Number ESI-9452859), a small,…

The study investigated differences in skill achievement with multiplication basic facts when a modified game required determination of two basic facts each time a game piece was played, while the standard game required the determination of only one basic fact. The data indicated no differences between treatments. (MK)

Graphing activities appropriate for grade levels K-8 are outlined and worksheets given. Topics involved include classifying, bar graphs, remainders from a series of divisions, and the greatest common factor of two numbers. (MP)

The nature of estimation and its relationship to measurement are discussed. Several ideas for teaching estimation and evaluating students' estimation skills are provided. (SD)

This study examined changes in 20 elementary teachers' beliefs about teaching and learning that occurred during the first 2 years of a 5-year implementation of cognitively guided instruction (CGI) as the basis of mathematics instruction. Teachers and mathematics educators from around North Carolina formed five local teams, each composed of two…

This is the first part of an article discussing methods for teaching the metric system. Measurement as a function, estimation, and textbook activities are covered. (DT)

Developing numerical relationships with calculators is emphasized. Calculators furnish some needed support for students as they investigate the value of fractions as the numerators or denominators change. An example with Logo programing for computers is also included. (MNS)

These worksheets feature activities concerning fractions. The primary-level activities provide opportunities to develop the concept of a fraction and the intermediate-level activities emphasize computation with fractions. (DT)

Describes a number of ways in which the adoption of the metric system in the United States will increase the effectiveness of mathematics teaching. It provides a concrete model for many concepts commonly taught in grades K-12, and thus provides a means by which confusion can be alleviated. (JR)
