Computer Literacy Objectives developed by the Minnesota Educational Computing Consortium (MECC) computer literacy study are given. The objectives are grouped under the six headings: Hardware; Programing and Algorithms; Software and Data Processing; Applications; Impact; and Attitudes, Values, and Motivation. (MK)

A mathematics course using programmable calculators, which was part of a summer enrichment program for upper elementary and junior high students, is described. (MK)

A teacher presents the case for organizing a mathematics club and outlines the procedures for doing so. (MK)

A method of teaching multiplication facts to remedial students using fingers and an alternate geometric proof developed by students are suggested. (MK)

Worksheets are provided for use by students in grades 8 and above when sectioning a tetrahedron. Lesson objectives include the discovery of generalizations regarding the cross-sections of a tetrahedron. (MK)

Using a geoboard to find polygons with given perimeters presents a problem which refines skills and provides an opportunity to inquire and discover. (MK)

A geometric model used to teach properties of rational numbers to college students is described. (MK)

A system of area measurement developed for the isometric geoboard is used to justify some relationships that are often proved using square units of area. (Author/MK)

A Reuleaux triangle is an example of a curve of constant width; the distance between parallel tangents is the same no matter which direction is used. A consideration of a particular set of Reuleaux triangles is offered which leads to a good example of problem-solving in geometry. (JN)

Describes a process which allows students to explore repeating decimals without being inhibited by the limitations of the calculator display. In addition, the process can take some of the mystery from the decimal forms of rational numbers. (JN)

Discusses two concrete models that have been useful in helping students understand operations with percentages. Includes information on materials needed, procedures for students, limitations, and instructional strategies. (JN)

Presents activities designed to provide students with an informal introduction to deductive logic through the use of the problem-solving skill of "eliminate possibilities." Includes rationale for the activities, background information, list of materials needed, objectives, four ready-to-copy student worksheets, and instructional strategies…

Discusses computer solutions for factoring problems. Includes listing for (1) a program that multiplies two user-chosen factors (X-R times X-S) and allows subsequent multiplications by more linear factors and (2) a program which computes P(X)/(AX plus B), where P(X) is a user-chosen polynomial and AX plus B is a user-chosen divisor. (JN)

Discusses the factoring of polynomials and Fibonacci numbers, offering several challenges teachers can give students. For example, they can give students a polynomial containing large numbers and challenge them to factor it. (JN)
