The Japanese, Chinese, and Russian abaci are described. Policies of the Japanese Education Ministry with regard to calculation are briefly discussed. (SD)

Indicates that there has been a lot of work done and that a great deal needs to be done in the future to explore the world of children's early number. Discusses the counting, the use of algorithm, practical mathematics, the use of manipulatives, individual differences and pedagogical concerns, and classroom applications. Contains 18 references.…

Describes the use of string figures to help students develop intuitive concepts about shape and space. (MKR)

In part 2, several surveying activities are suggested. The first, a radial survey, combines activities for dealing with length and angles previously mentioned in part one. The second suggested survey is an offset survey; needed implements and procedures are described. Two types of triangulation and a plane table survey are also discussed. (MK)

Solid polyominoes are formed by gluing cubes together so that the two faces of adjacent cubes are wholly in contact. Tessellations of a three-dimensional space with solid pentominoes are discussed and illustrated. (MP)

A new model of geoboard based on an axis, the "Gyratory Geoboard," is described. Some activities for teaching plane rotations and central symmetry are included. (MNS)

Descriptions are given of how groups aged 7, 10, and 13 tackled the problem of how many squares are on a chessboard. Teachers noted that often the less able children were the ones with ideas, whereas the able ones became impatient and were unwilling to go on trying. (MNS)

Methods of constructing polyhedra models are described. (DT)

A survey of what items of equipment are considered useful in teaching mathematics by secondary school teachers is presented. (JP)

Some activities with geoboards done by pupils aged 10 and 11 are first reported, followed by an analysis and development of extended mathematical ideas. (MNS)
