Computers have been in schools and indeed some mathematics classrooms for more than 35 years. Some schools have chosen to centralise their computers in laboratories, while others have a mix of configurations and networks. Whatever the case, how extensive has been the classroom use of computers for teaching and learning in mathematics? What has…

Describes some of the thinking associated with the improvement of tasks, suggesting some guidelines for others to consider in producing written mathematics materials for young students. Provides examples of written mathematics materials. (ASK)

Describes a project that features a video in the form of a documentary built around a series of six case studies in mathematical thinking: geometry, number, measurement, algebra, chance and data, functions, and calculus. Chooses an example from each area to illustrate inductive and deductive thinking-patterns and proof. (ASK)

A number of outdoor practical activities involving measurement and shape are given. (DT)

Some materials are examined which try to cultivate skills and concepts such as estimation, approximation, significant digits, place value, and repeating decimals. Also discussed are repercussions and longer term implications on the use of minicalculators. (MP)

The last 13 of 32 exercises of a course designed to give a wide range of skills in deductive, inductive, and indirect methods of proof in geometry are presented. (MP)

Two articles in the "Scientific American" form the background of this note. The rainbow angle for the primary bow of a monochromatic Cartesian rainbow is calculated. Special projects for senior high school students could be patterned after this quantitative study. (MP)

From a set of history of mathematics materials, a play and an article were selected for evaluation through opinions of experts, survey of teachers, and changes in students' affective and cognitive outcomes. (MP)

This paper contains the text of an address read at the Sixth Biennial Conference of the Australian Association of Mathematics Teachers. The author discusses an Australian Academy of Science project which focuses on mathematics applications materials for secondary school students not intending to proceed to post-secondary studies in mathematics.…

A game is presented in which computation by a stepping-stone method is used to solve minimax problems. An additional application of this game is used for finding the Pearson correlation coefficient by non-parametric techniques. The game provides considerable computational practice as well as a motivational problem solving situation. (JP)

This article offers a novel way of having students construct models of the five Platonic solids without the use of glue. Patterns and directions for students are provided. (DT)

This section contains four worksheets for games on estimation. Impact, Crossfire, Fire One, and Fire Two each require the use of calculators to focus on place value, multiplication, or division. (MNS)

Outdoor mathematics is the subject of four worksheets. The activities concern pacing to determine perimeter, estimating a kilometer, area of an irregular figure, and estimating the height of a tree. (MNS)

Presented are examples from geometry that are designed to investigate whether situations fit Euclidean geometry. Diagrams and activities are provided for examples. (RH)

Described is a project, "Mathematics at Work," being produced by the Australian Academy of Science to meet the needs of students staying in school to years 11 and 12 and requiring a "relevant" mathematics curriculum. Materials have been produced and are being used in a trial program. Additional materials are in preparation. Characteristics of the…
