Dialectic Stage Math:
Grades 7-9



Using the Online Catalog


Option 1: VideoText Algebra
For 7th-9th grades and up, or after completion of a complete course in Arithmetic as described in Grammar Stage Math. Algebra is the next step after Arithmetic, and is the language in which all higher math study occurs, and is therefore the foundation for all higher math study, including Geometry. VideoText Algebra combines the material learned in Algebra I and II into one 1-year course. This is CCH’s top choice for Algebra instruction in the dialectic stage.

Option 2: Harold Jacobs Mathematics
For 7th-9th grades and up, or after completion of a complete course in Arithmetic as described in Grammar Stage Math. Harold Jacobs texts presents the subjects of Algebra and Geometry in a dialectic way, allowing children to think through and analyze the concepts presented. Algebra and Geometry are one-year courses; CCH recommends taking Algebra in 7th grade, then a Logic course in 8th grade, then Geometry in 9th grade.

Option 3: Euclid’s Elements
For 7th-9th grades and up, or after completion of an Algebra course, either VideoText, Harold Jacobs, or something else. For 2000 years Euclid’s Elements have been used to teach logical thinking through the study of geometry.

Option 4: Online Mathematics Tutorials
For 7th-9th grades and up, or after completion of a complete course in Arithmetic as described in Grammar Stage Math. Online Mathematics Tutorials provide an excellent education in Algebra and Geometry.


VideoText Algebra

VideoText AlgebraVideoText Algebra
Thomas E. Clark

CCH’s top choice for Algebra instruction, for 7th-9th grades and up, or after completion of a complete course in Arithmetic as described in Grammar Stage Math. VideoText Algebra is a unique approach to algebra among courses available. First, it contains all the material covered in both Algebra I and Algebra II in one course. Years ago, there were only two mathematics courses required for high school graduation--one year of Algebra, and one year of Geometry. When it was decided to increase mathematics instruction, a second year of Algebra was tacked on after the traditional Algebra - Geometry progression, called Algebra II. But since it had been over a year since the student had taken an Algebra class, the majority of the Algebra II textbook was a repeat of Algebra I. In only the final few chapters of the text was there any new material, and that is the way it has continued from that day to this. But it is craziness to take Algebra II after Geometry--a complete understanding of Algebra is the foundation of all higher mathematics, including Geometry! Mr. Clark, mathematics teacher, math textbook author for traditional text publishing companies, and former superintendent of mathematics instruction for the state of Indiana, has therefore combined the complete subject matter of algebra, Algebra I and II, in one course. When the student has completed VideoText Algebra, he should receive credit for a one-year course in Algebra I and a one-year course in Algebra II.

Second, VideoText Algebra instructs the student first in the language of mathematics, its grammar and syntax, if you will, and therefore gives the student vital tools to truly understand algebra, the language in which all higher mathematics is done. This approach makes algebra simple to understand for even the most math-phobic. I know, because my oldest daughter, who has since graduated from homeschool high school, was math phobic. (Not any longer, thanks to VideoText Algebra.) We tried Saxon Algebra I, which did nothing but cause her hours of tears and frustration daily, and added to her I-knew-I-couldn’t-do-math mentality. She then studied Harold Jacobs Elementary Algebra, which she did complete with a B average, with much labor and determination, over the course of two years. But when we chose VideoText Algebra for her Algebra II course, she cried tears of joy when she first began working in it. “I finally understand math! I am not dumb in math after all!” were her exact words. It broke my heart, but made me extremely grateful to Mr. Clark for his unique approach.

Third, VideoText Algebra tells the truth about mathematics, something that even Jacobs’ Algebra sometimes avoids. For example in the first chapter of Jacobs’ Algebra, he states that no number can be divided by zero, for the answer is meaningless. Period. The student takes that on faith, and remembers it with no further explanation. In VideoText Algebra however, students divide numbers by zero, to find out what happens. (Yes, it CAN be done.) They learn why division by zero is meaningless, and that learning why really satisfies their natural questions and solidifies the basic principles in their memory, with understanding.

The lessons in VideoText Algebra are taught on video, and include 5-7 minutes of instruction. The exercises are contained in the Student Workbook, and include 20 problems per lesson. That’s it. When the student learns why, and understands the principle, he does not have to do 50-100 problems per lesson to get formulas drilled into his head by rote. Complete solutions to every problem, including every step worked, come in the Solutions Manual for the teacher or parent. This lets the parent go over problems missed with the student, who can then see exactly where he went wrong, and why. VideoText Algebra is expensive, because of the videos. This is the only expensive program I recommend in my whole catalog, for any subject. But the 6 modules can be purchased separately, as the student needs them over the course of the year, so the parent in effect can make payments on the program. The organization and presentation of the material to be learned is so simple, elegant, well-done, and unique among algebra courses, that it justifies the expense in my mind.

The following Harold Jacobs student texts can be ordered from Amazon.com. While some teacher’s helps can be ordered from Amazon, some can not. However, all the teacher’s helps are in fact in print as of July 1, 2001. Contact the publisher, W. H. Freeman and Company, to obtain teacher’s helps not available through Amazon.com. Be sure to have the ISBN numbers of the materials you would like to order in front of you when contacting the publisher.

Elementary AlgebraElementary Algebra
Harold R. Jacobs

For 7th-9th grades and up, or after completion of a complete course in Arithmetic as described in Grammar Stage Math. The Jacobs texts are self-instructing with the material presented in a dialectic way of encouraging children to think through the concepts presented. Harold Jacobs says of his series, “What a wonderful thing it would be if we could make each and every one of our lessons entertaining as well as informative! [I have] made this a major goal ... [as well as] to help students learn how to teach themselves. ... I think that reading the lesson should be an important part of every assignment and have tried to write each one in such a way that it can be read with understanding.” He succeeds. Harold Jacobs Elementary Algebra (ISBN 0716710471) covers all the material in Saxon’s Algebra I, and some of the material in Saxon’s Algebra II. Seventeen chapters thoroughly cover fundamental operations, functions and graphs, integers, rational numbers, equations in one and two variables, simultaneous equations, exponents, polynomials, factoring, fractions, square roots, quadratic equations, real numbers, fractional equations, inequalities, and number sequences. Each chapter contains multiple lessons that introduce that chapter’s concept line upon line and logically. Each lesson contains plenty of practice exercises arranged in four sets. Set I reviews ideas from previous lessons, sets II and III apply the concepts of the current lesson, and Set IV challenges advanced students. In this way each lesson can be custom designed, if need be, for slower, average, and advanced students. The answers to Set II problems are in the back of the student text; the answers to Set I, III, and IV problems are in the Elementary Algebra Teacher’s Guide (ISBN 0716710757). The texts also include mid-term and final year reviews which help prepare the student for the semester exams (purchased separately, ISBN 0716710773) or which can be used in place of semester exams.


GeometryGeometry
Harold R. Jacobs

For 8th grade and up, or after completion of a course in Algebra (Algebra I and II). Harold Jacobs Geometry (ISBN 071671745X) draws from Euclid, teaches how to write proofs, and includes work in proofs in each of its chapters. A unique aspect of this text is its Algebra review built into the end of each chapter. It is a traditional geometry course, covering the topics of Introduction to Euclid, the Nature of Deductive Reasoning, Points, Lines, and Planes, Rays and Angles, Congruent Triangles, Inequalities, Parallel Lines, Quadrilaterals, Transformations, Area, Similarity, Right Triangles, Circles, Concurrence Theorems, Regular Polygons and the Circle, Geometric Solids, Non-Euclidean Geometries, and Coordinate Geometry. The Geometry text is laid out similarly to Elementary Algebra, with exercises contained in three Sets per lesson. The answers to the exercises as well as additional teacher helps are in the Geometry Teacher’s Guide (ISBN 0716717484) The texts also include mid-term and final year reviews which help prepare the student for the semester exams (purchased separately, ISBN 0716717476) or which can be used in place of semester exams.


Euclid’s Elements

Euclid’s ElementsEuclid’s Elements
Sir Thomas Heath, translator and editor

For 8th grade and up, or after completion of a course in Algebra (Algebra I and II). Euclid’s Elements is an alternative text to teach Geometry. Actually, modern Geometry texts are the alternative, as Euclid has been the standard Geometry text for millenia. Working Euclidean proofs provides an excellent education in logical and precise thinking. Abraham Lincoln said that besides the Bible, Euclid was his most treasured book, as its study enabled him to become the devastingingly logical and articulate lawyer for which he was famous. This unabridged publication of the original enlarged edition contains the complete English text of all 13 books of the Elements, plus analyses of each definition, postulate, and proposition. Please note that this edition actually comes in 3 volumes: Volume 1 includes Elements Books I-II, Volume 2 includes Elements Books III-IX, and Volume 3 includes Elements Books X-XIII.


Online Mathematics Tutorials

Escondido Tutorial Service Mathematics TutorialsEscondido Tutorial Service Mathematics Tutorials
Fritz Hinrichs, tutor

For 7th-9th grades and up, or after completion of a complete course in Arithmetic as described in Grammar Stage Math. Escondido Tutorial Service is the pioneer in internet tutorials for home and private schooled students. Tutor Fritz Hinrichs, a graduate of St. John’s College, is also a recognized expert in classical Christian education, being written about in numerous publications (The New York Times and The Future of Home Schooling by Michael Farris, for example) regarding distance learning and classical education, as well as appearing as a frequent columnist and conference speaker. He uses the Saxon texts for Algebra, and Euclid’s Elements for Geometry. The pitfalls of Saxon’s teaching method are lessened in this case, as the tutor mediates the lesson presentation and is able to present the material in a dialectic stage manner. Saxon Algebra 1/2, Saxon Algebra I, Saxon Algebra II, and Euclidean Geometry Online Tutorials are all available.
