Describes a way to teach secondary teacher education majors to use simple manipulative objects to teach a few vocabulary concepts in their content area. (SR)

This article compares the relative merits of using Cuisenaire rods (unsegmented, unnumbered, and representing continuous quantities) and number sticks (segmented, numbered, and representing discrete quantities) to introduce number and arithmetic concepts to beginning students or students with learning difficulties or mental disabilities.

Another way to add and subtract, in which the mental regrouping strategy is applied to an original 10-structure, is presented. Pupils use a visual model, called "little person," to move from counting to visualization. Originally designed for use with pupils with learning disabilities, this method has wider applicability.

Discusses the renewed interest in clay as a modeling compound in early childhood programs; describes the nature of clay and presents a working vocabulary. Suggests methods of working with clay, including introducing clay to children, discovering its uses, clean up, firing clay, and finishing baked clay. Includes activity suggestions and…

Describes the use of unit blocks with young children in early childhood education (ECE) settings to expand all areas of the curriculum. Discusses the origin of blocks in ECE programs, presents developmental stages of block play, describes children's building styles, and makes recommendations for getting started in block play for children of…

Describes a project to develop a lending library to support and extend the elementary mathematics curriculum with the goals of implementing the National Council of Teachers of Mathematics (NCTM) connections standards; enhancing parental involvement in mathematics learning; encouraging active, hands-on approaches to mathematics at home; and…

Identifies ways for children to learn about shapes through hands-on activities. Offers activities specifically for infants, toddlers, preschoolers, and school-age children. (DLH)

Young children do science exploration and observation every day in their play. They spontaneously engage in parts of the scientific inquiry process--wondering, asking a question, planning how to answer the question, documenting their work, thinking about what happened, and sharing their results with others. Conducting an entire experiment is…

This elementary activity follows the 5-E Learning Cycle as described by Bybee et al. (1989) and integrates literature from Dr. Seuss. Students observe and identify characteristics of several slime substances and must make comparisons to determine which one most closely resembles the slime substance described by Dr. Seuss. To maximize this…

The authors discuss mass as one of the three fundamental measurements (the others being length and time), noting that estimation of mass is little taught and assessed in primary schools. This article briefly explores the reasons for this in terms of culture, practice, and the difficulty of assessing estimation of mass. An activity using the…

This study examined the outcomes of a competing activities intervention to decrease skin picking exhibited by a 9-year-old student with comorbid diagnoses. Results of an ABCBAB design revealed that the use of student-selected manipulatives resulted in reduced skin picking. (Contains 1 figure.)

This study was designed to investigate the impact of using computer-simulated (virtual ) manipulatives and hands-on (concrete) manipulatives on elementary students' learning skills and concepts in equivalent fractions. The researcher's primary interest was whether or not students who used virtual manipulatives would out-perform students who used…

Several researchers have noted how children's whole number schemes can interfere with their efforts to learn fractions. An Australian study found that children who were successful with the solution of rational number tasks exhibited greater whole number knowledge and more flexible solution strategies. Behr and Post (1988) indicated that children…

The number of school age children with Attention Deficit Disorder (ADD) has increased over the past decade to 10-20% of the elementary school population and is expected to continue to grow. The need to understand these children and effectively teach them is obvious. This paper examines the research literature to determine the best and most current…

In these two companion papers, a learning activity is introduced that teaches students how mathematics works through the visual aid of picture grids. The picture grids are composed of 60 different acrylic stained-glass window overlays. Each fractional part is represented by a different color: fifths are green, quarters are yellow, etc. The square…
