This article describes a project in which certain key concepts in probability were explored using graphics calculators with year 10 students. The lessons were conducted in the regular classroom where students were provided with a Casio CFX 9850 GB PLUS graphics calculator with which they were familiar from year 9. The participants in the…

An approach to equation solving using calculators that promotes the trial-and-error method as a useful strategy when combined with calculators is presented. The approach is specifically geared towards the secondary schools as a way of moving to harder equations that the linear and quadratic ones traditionally used. (MP)

Some examples of typical nonrelevant textbook problems on probability are followed by more complex problems pulled from the real world. The resource used in this report is Newsweek magazine; and is used to help demonstrate that from the very beginning, lessons on conditional probability can have relevance. (MP)

Presents graphing calculator activities that rely on resolving the magnitude and direction form of vectors into their Cartesian components so that they are suitable as applications for vector or trigonometric relationships for years 10-12. (ASK)

Discusses the Texas Instruments calculator the TI-92 and how it can be an effective tool in the mathematics classroom. Provides examples of combining the algebra capabilities of the calculator and Cabri-Geometry II with graphing, tables of values, statistics, programming, and a simple text editor to enhance mathematics instruction.

Programmable calculators are useful tools in the classroom that are often overlooked. This report gives examples of problems and activities that can be brought within the scope of such calculators. (MP)

New approaches to the teaching of introductory algebraic concepts are discussed. Their use in the Approaching Algebra Numerically Project in some middle schools in Ohio is reviewed. Some implications for use in Australian schools are considered. (MNS)
