A series of interesting mathematical applications for the greatest integer function are presented. (JT)

Three activities involving children with the probability concepts of random selections and sample size are provided. (JT)

Geometry and a hand-held calculator are used to find a value of pi accurate to five decimal places. (CP)

Provides a metric area model which may be used to explain the square root algorithm. (CP)

This paper contains part of the text of an address given at the sixth Biennial Conference of the Australian Association of Mathematics Teachers concerning current developments in the secondary school mathematics area in Australia. A list of strong high school mathematics program syllabi is also given. (MN)

The author mentions several broad types of student elementary algebra errors, including incorrect cancellation and cross-multiplication, notes confusing terms and factors, and gives several suggestions to help students avoid these. (MN)

An elective course aimed at giving tenth-grade students some experience with practical arithmetic problems is outlined. The two-week course is designed primarily for students who will be leaving at the end of the year and includes topics such as calculators; earning, spending, and saving money; tax; and buying a car. (MN)

Four games that reinforce the concepts of place value and ordering numbers are described. (JT)

Through the use of sequences, geometric progressions and permutations, the author investigates some interesting and unusual questions concerning the number of moves required by each disc in solving the Tower of Hanoi puzzle. (JT)

The author argues that the idea of successive approximations is one of the most important in applied mathematics. The role of approximation in the development of the calendar is described. (SD)

The author recommends the use of flow charting to help students understand the manipulation of algebraic formulae. He identifies some problems with flow charts and suggests an alternative method of constructing flow diagrams. (SD)

A revised version of the Nuffield project is designed to address instructional and curricular problem areas related to the language of mathematics and practice with and reinforcement of application of basic concepts and skills. (SD)

A series of examples is provided of types of mathematical exposition which cause students difficulty for reasons other than lack of understanding of some mental process. (SD)

The "old math" and "new math" are compared on the basis of their goals and objectives. The authors argue that revision in curriculum and in research related to mathematics education is necessary, and provide several suggestions for directing change.

The idea of mathematical camps for bright pupils is discussed. Some activities in such a camp include meetings with scientists, mathematical evenings, brain-teachers, semi-seminars, brainstorming, guiding texts, Olympian club, consultations, adventures, marches, and various games and competitions. These were evaluated by camp participants in…
