*Arithmetic, An Individualized Approach* can be used by students in need of a complete arithmetic course or for those with holes in their backgrounds that constantly interfere with progress in math courses beyond arithmetic. Every objective in the course is thoroughly explained and developed. Numerous examples illustrate every concept and procedure. Student involvement is guaranteed as the presentation invites the student to work through partial examples. Each unit of material ends with an exercise specifically designed to evaluate the extent to which the objectives have been learned. The student is always informed of any skills that were not mastered.

*Beginning Algebra, An Individualized Approach* is a full instructional system for a first course in Algebra. It is designed for students with an adequate arithmetic proficiency. The instruction develops a base for the further study of Algebra. It begins by explaining basic algebraic concepts with whole number examples. As the concepts are developed, the examples are expanded to signed numbers (integers) and then fractions (rational numbers). Every objective is thoroughly explained and developed. Numerous examples illustrate concepts and procedures. Students are encouraged to work through partial examples. Each unit ends with an exercise specifically designed to evaluate the extent to which the objectives have been learned. The student is always informed of any skills that were not mastered. The instruction depends only upon reasonable reading skills and conscientious study habits. With those skills and attitudes, the student is assured a successful math learning experience.
