Describes how to use common dice numbered 1-6 for simple mathematical situations including probability. Presents a lesson using regular dice and specially marked dice to explore some of the concepts of probability. (KHR)

Describes the use of paper folding to create a rich environment for discussing algebraic concepts. Explores the effect that changing the dimensions of two-dimensional objects has on the volume of related three-dimensional objects. (Contains 13 references.) (YDS)

Movement activities which utilize a rectangular chute are described. The chute, in addition to its motivational qualities, can be employed in several fitness areas--flexibility, muscular strength and endurance, and cardiorespiratory endurance. (IAH)

Describes hands-on class activities in which high school geometry students can create nested Platonic solids from posterboard. Includes discussion of the algebraic and pictorial relationships between pairs of Platonic polyhedra. (MKR)

The effectiveness of using a set of models in two protein synthesis laboratory exercises accompanied by a series of two lectures on the topic was assessed. The purpose, procedure, example test items, the findings, and a discussion are included. (KR)

Finds that an elementary mathematics-methods course provided preservice teachers with important knowledge and experience concerning the use of manipulatives. Notes that the preservice teachers learned mathematical content through the use of manipulatives in the course, and that they were concerned that difficulties might impede their ability to…

Presents an investigative process of conjecture followed by proof by induction using a combination of manipulatives and technology, placing special emphasis on the use of different representations. (ASK)

Presents two hands-on mathematics activities for teaching K -3 students to experience fractions on a tactile level. The first uses chocolates to demonstrate that fractions can be part of a whole, can be part of a set, and are equal parts. The second has students design a classroom fraction museum with fraction exhibits designed and presented by…

Examines two types of computer environments suggested by the new Standards, one of which is the computer manipulative and the other a navigational environment such as the computer turtle. Discusses the contribution that these environments can make to young children's mathematics learning. (Contains 12 references.) (ASK)

Describes and analyzes a learning episode in which two children in year 4 interact with each other and their teacher while playing a probability game involving chocolate M&Ms. Children developed key ideas in probability from a game that was designed to produce cognitive conflict. (ASK)

Presents an activity in which students must arrange five fractions represented by dominoes in ascending order and justify their reasons for the ordering. Representing common fractions with dominoes helps identify students' misconceptions about fractions. (ASK)

We investigate how vision affects haptic performance when task-relevant visual cues are reduced or excluded. The task was to remember the spatial location of six landmarks that were explored by touch in a tactile map. Here, we use specially designed spectacles that simulate residual peripheral vision, tunnel vision, diffuse light perception, and…

This research study examines the instructional practices of 10 middle grades teachers related to their use of manipulatives in teaching mathematics and their control of mathematics tools during instruction. Through 40 observations of teaching, 30 interviews, and an examination of 67 written documents (including teachers' plans and records),…

A number of chemical concepts can be easily illustrated in a more friendly way to children by using toys as teaching tools in the classroom. Some of the examples illustrated are shrinking toys, drinking birds and hand boiler.

Integration of subject areas with technology and thinking skills is a way to help teachers cope with today's overloaded curriculum and to help students see the connectedness of different curriculum areas. This study compares three authentic approaches to teaching a science unit on bird adaptations for habitat that integrate thinking skills and…
