Presents a worksheet on graph paper that allows students to determine the perpendicular bisectors of given segments by folding the paper. Students then determine the slopes of the perpendicular bisectors and use inductive thinking to discover the relationship between the slopes of perpendicular lines. (MDH)

Citing examples from the author's third grade mathematics classroom, describes problems stemming from the use of concrete objects (e.g., fraction bars, base-10 blocks, and popsicle sticks). The vignettes show the fallacy of assuming that students will automatically draw the conclusions that their teachers want simply by interacting with particular…

Presents a student project that requires students to create a puzzle involving some form of manipulative and present it to the class with an advertisement. Uses writing to have students report on their progress. (MDH)

Discusses North Carolina's alternative assessment program for first and second grades, the process of implementation, knowledge gained from the program, and implications for implementing Standard 6 (focusing on analyzing and interconnecting teaching and learning) of the National Council of Teachers of Mathematics Professional Teaching Standards.…

Presented are student activities that involve two standard problems from geometry and calculus--the volume of a box and the bank shot on a pool table. Problem solving is emphasized as a method of inquiry and application with descriptions of the results using graphical, numerical, and physical models. (JJK)

Four activities which illustrate the use of manipulative materials and computers in problem solving at the elementary level are presented. Each activity discusses large group activity and a computer activity. (CW)

Compared pre-service elementary teachers' beliefs about mathematics and science teaching before and after immersion in an integrated, spiral-based, inquiry approach within a mathematics and science methods course. Results highlighted: the importance of the teacher's role; use of methods, strategies, and styles; use of manipulatives and materials;…

This article describes a project done in middle school mathematics classes that addresses the learners' diversity and acknowledges their heritage, multiple abilities, and learning styles. The project, with the use of cultural artifacts and creative stories, enables one to teach and assess mathematics in an imaginative and creative way that both…

The "Central Dogma" of genetics states that one gene, located in a DNA molecule, is ultimately translated into one protein. As important as this idea is, many teachers shy away from teaching the actual mechanism of gene translation, and many students find the concepts abstract and inaccessible. This article describes a unit, called Genetics…

This handbook was designed for those individuals interested in increasing their understanding of basic movement skill development, observation and assessment, and program implementation. The basic movement skills identified in the text are the essential building blocks on which all physical education, active play, recreation, and physical activity…

This practicum project involved working with four preschool children with mental disabilities to increase their cognitive abilities through the use of computer-based instruction and use of manipulative materials. It also sought to improve the children's social-emotional development and self-esteem. The developmental levels of the four students…

Recent reports indicate that although 17-year-old high school students know some basic addition and subtraction facts, few of the students are capable of solving multi-step mathematics problems. A non-equivalent pretest-posttest control group design study examined the effects of a teaching method emphasizing manipulative use on the mathematics…

This guide is support material for geometry teachers in middle schools or high schools in South Carolina. The guide describes the content of each program in the television series and suggests further learning activities for the students. The geometry that underlies the world around us is presented through applications. Contents of the series…

This study sought to find a way to help children from educationally disadvantaged families to improve their cognitive and language abilities and thus improve their achievement in school. Specifically the study investigated the effectiveness of guided experiences with clay in promoting cognitive, affective, and language growth of educationally…

This paper reports a comparative analysis of beginning and experienced teachers' thinking about teaching subtraction with regrouping commonly called "borrowing"), and the role that textbooks play in their deliberations. Twelve beginning and nine experienced teachers appraised and compared two contrasing textbook selections dealing with this topic…
