These materials are intended to provide meaningful mathematical experiences for pre-algebra students. These experiences emphasize the development of computational skills, mathematical concepts, and problem-solving techniques. This bulletin may be used as the basis for the second term of a one-year course, or for the second year of a two-year course. The complete course is divided into 12 basic units, the last six of which are in this bulletin. These are: (1) solving simple equations; (2) tables, graphs and coordinate geometry; (3) banking; (4) areas; (5) indirect measure and scaling; and (6) solid geometry. Each individual lesson includes the aim, performance objectives, essential vocabulary, specific teaching suggestions, applications, and a summary. The mathematical skills and concepts are arranged in a sequential order allowing for the spiraling of skills among units and semesters. (PK)

The Minnesota School Mathematics and Science Teaching (MINNEMAST) Project is characterized by its emphasis on the coordination of mathematics and science in the elementary school curriculum. Units are planned to provide children with activities in which they learn various concepts from both subject areas. Each subject is used to support and reinforce the other where appropriate, with common techniques and concepts being sought and exploited. Content is presented in story fashion. The stories serve to introduce concepts and lead to activities. Imbedded in the pictures that accompany the stories are examples of the concepts presented. This unit introduces students to the Cartesian coordinate system and, in particular, to the graph of a linear equation. Ideas associated with Pascal's triangle, groups, and vector spaces are also introduced informally. Worksheets and commentaries to the teacher are provided and additional activities are suggested.
