The Secondary Mathematics Individualized Learning Experiment (SMILE) is described. A sample teacher record sheet and a student activity sheet are displayed. (SD)

Many geometric principles can be discovered or illustrated using toothpicks in conjunction with two longer straightedges. (SD)

Reluctant learners made plastic geometric shapes for use in classroom activities. (SD)

Problems concerning the number of arrangements of eight unit-cubes, volume, and surface area are presented in the worksheet on cubes. (DT)

Experience with data processing must be included in courses dealing with computer science. A series of examples of data processing problems suitable for classroom use is presented. (SD)

A mathematical model giving weight which can be lifted as a function of bodyweight is formulated and compared with the actual data for the flyweight through the heavyweight classes. (MN)

The twelve curricular packets developed by the Mathematics for the Majority Continuation Project are described. The objectives of the project, development of materials and recommended methods of use are discussed. (SD)

A classroom activity is illustrated in which vectors are drawn in the first quadrant of a rectangular coordinate system forming a vector polygon which is then reflected about each axis. (MN)

Details are given concerning instructional materials on basic geometry concepts for secondary school students. The contents of the learning package and format of the material are described, samples from accompanying workbooks are presented and discussed, and enrichment activities are suggested. (DT)

Provides illustrated problem settings that serve as models for generating new investigations of the three-dimensional figures that result from a transformation of two-dimensional patterns. (JJK)

The School Mathematics Program (SMP) is criticized for providing the upper 20 percent of the students with insufficient practice on working examples. (SD)

The adoption of the School Mathematics Project (SMP) materials by Botswana, Lesotho, and Swaziland is described. Some of the materials, especially work cards, have been modified for African use, and the countries intend to continue use of this program. (SD)

Some functions on digits of positive integers are presented as possible sources for useful investigations by students, particularly through the use of calculators and computers or in the writing of small proofs. The material is designed to encourage students to conduct their own investigations. (MP)

The author calls for teachers to seek changes in the content of school mathematics curriculum which will reflect the growing diversity of mathematical application. Two examples of such application which can be described by simple mathematics and involving easy manipulation are given. (MN)

It is shown that, by taking as the basis unit vectors along the sides of an equilateral triangle, certain isometric transformations can easily be determined in matrix form. (MN)
