Nathan entered third grade having already constructed a Generalized Number Sequence (GNS) for whole numbers that enabled him to coordinate sequences of multiples to find a common multiple of two whole numbers. Nathan was able to apply the operations of his GNS to his understanding of part-whole relations and his emerging use of fractional…

This collection of lesson plans and activities for students aged 9-11 years is based on a science curriculum developed by a group of Caribbean nations. The activities pertain to topics such as place value, prime and composite numbers, the sieve of Eratosthenes, square numbers, factors and multiples, sequences, averages, geometry, symmetry,…

Designed for teaching the related services staff, residential care providers, and families of individuals with severe hearing and vision impairments, this booklet explains the issues related to developing a communication system using textures. The texture symbols described are intended for use by individuals with dual sensory and multiple…

Describes some results of a project funded by the National Science Foundation to investigate ways to make a college biology course accessible to visually impaired students, including use of tactile diagrams as an alternative to microscopes and a variety of measuring techniques. (Author/SK)

The Springs task, an individually administered measure of ability to criticize and control experiments, is described. The task has characteristics similar to Inhelder and Piaget's Bending Rods task; it yields scores on naming variables, controlling variables, and analyzing experiments. (See also RIE: ED 163 092.) (JKS)

Presents a series of lessons that extend the concrete experiences many elementary students have had with attribute blocks to provide middle school students with informal opportunities to explore the concepts and properties of relations and functions. (DDR)

A theory is proposed for how students develop competence with the written symbols of decimal fractions. Competence is viewed as the cumulative and sequential mastery of four separate cognitive processes. The theory was tested with small groups of students, most of whom were able to acquire the first two processes. (MNS)

Presents a sequence of hands-on activities to help students understand the concept of arithmetic mean and gain experience in using mathematical models. Students create models in the process of solving problems and communicate to the class the meaning attached to the models. (MDH)

Presents observations about the influence of mathematics textbooks and suggests ways to use textbooks to advantage while reordering the sequence and emphasis of topics to allow time for alternative activities. The fifth-grade mathematics curriculum is examined as an example. (MKR)

Presents an instructional approach that utilizes paper-folding activities to help students understand the concept of fractions. Utilizes an area model of multiplication to extend the concept of multiplication of whole numbers to multiplication of fractions. (MDH)

Investigated is whether children would spontaneously model problems with superfluous information and whether their modeling would facilitate problem solving. Included are the addition/subtraction story problems used in this study, introduction, method, results, discussion, and conclusions. (KR)

Describes the ways in which primary grade science teachers can use hands-on scientific activities to answer children's questions about science. In such activities, children discover and experiment with materials and objects to understand scientific ideas and processes. Suggests that teachers should encourage children's curiosity. (BB)

Describes a summer mathematics inservice workshop for 39 elementary teachers from rural, small schools throughout New Mexico. Focused on minority participation, hands-on activities, and improvement of attitude towards the teaching of mathematics. Posttests revealed improvement in knowledge of manipulative use, confidence in use of manipulatives,…

Presents a series of hands-on activities for grades K-2, 3-4, 5-6, and 6-8 using the common theme of kites to develop number sense in basic operations and fractions. Teachers' guides and worksheets are provided. (MDH)

Explores three questions related to the kindergarten mathematics curriculum: (1) How much do young students' limited abilities to process information hamper performance on worksheet tasks? (2) How is mathematics currently taught in kindergarten? and (3) What materials and activities are appropriate for mathematics learning in kindergarten? (MDH)
