PreAlgebra (Free)
Welcome to one of the most popular free online PreAlgebra courses on the Web. These are times of rapid change, and this study program is changing with those times. Teachers and home-school mentors, you will find slight changes taking place, but we try to select and manage changes so that you will be able to adjust your lesson plans with little or no special revisions. We are also busy completing and enhancing some sections that have not been up to the standards of quality that tens-of-thousands of clients have come to expect over the past fifteen years.

Understanding Algebra (Free)
An online algebra text by James W. Brennan. The complete contents of this algebra textbook are available on this site. This text is suitable for high-school Algebra I, as a refresher for college students who need help preparing for college-level mathematics, or for anyone who wants to learn introductory algebra. I am especially pleased to help homeschoolers. Also available on Kindle.

Calculus on the Web (Free)
COW is an internet utility for learning and practicing calculus. It was designed at Temple by two members of the Temple University Mathematics Department, Gerardo Mendoza and Dan Reich. The principal purpose of COW is to provide you, the student or interested user, with the opportunity to learn and practice problems in calculus (and in the future other topics in mathematics) in a friendly environment via the internet. The most important feature of the COW is that you get to know whether your answer is correct almost immediately. It is as if you had a tutor looking over your shoulder and helping you along as you work. This will be true no matter where you are or what computer you use, as long as it is connected to the internet and has a web browser.

Geometry in Art & Architecture (Free)
A dynamic branch of mathematics, geometry also serves as a creative tool for engineers, artists, and architects. Squaring the Circle: Geometry in Art and Architecture is the first textbook to cover both art and geometry extensively. The text’s wide-ranging exercise sets and related projects allow students to practice and master the mathematics presented. Each chapter introduces mathematical concepts geometrically and illustrates their nontraditional applications in art and architecture throughout the centuries.

Euclid’s Elements (Free)
Supplement to the course above. One of the most beautiful and influential works of science in the history of humankind. Its beauty lies in its logical development of geometry and other branches of mathematics. It has influenced all branches of science but none so much as mathematics and the exact sciences. The Elements have been studied 24 centuries in many languages starting, of course, in the original Greek, then in Arabic, Latin, and many modern languages.

Math-U-See ($$)
Math-U-See’s unique instructional approach makes it easier for instructors (parents, teachers, and tutors) to help students progress in mastering fundamental math skills and concepts. Math-U-See’s simple but powerful set of colorful manipulatives allows abstract math concepts to be represented in clear, relatable ways. These manipulatives, combined with distinctive strategies presented through videos, textbooks, practice, systematic review, and assessments, guide students from concept to concept as they build a solid understanding of mathematics. Because the focus is on understanding math concepts, the curriculum is not organized traditionally by grades; rather, Math-U-See is a skills-based program that focuses on student mastery of a concept before progressing to the next concept.

Singapore math
The Singapore math method is a highly effective teaching approach originally developed by Singapore’s Ministry of Education for Singapore public schools. The method has been widely adopted in various forms around the world over the past twenty years following our introduction of the curriculum to the U.S. in 1998. Singapore math is a highly effective teaching approach that instills deep understanding of mathematical concepts. Raised U.S. student performance through our thoughtfully designed and
evidence-based math programs.

Elementary Statistics (Free) 
Elementary Statistics is an introduction to data analysis course that makes use of graphical and numerical techniques to study patterns and departures from patterns. The student studies randomness with emphasis on understanding variation, collects information in the face of uncertainty, checks distributional assumptions, tests hypotheses, uses probability as a tool for anticipating what the distribution of data may look like under a set of assumptions, and uses appropriate statistical models to draw conclusions from data. The course introduces the student to applications in engineering, business, economics, medicine, education, the sciences, and other related fields. The use of technology (computers or graphing calculators) will be required in certain applications.

Teaching Textbooks
Designed specifically for independent learners, they have more teaching/explanation than any other product on the market. Independent learners needed a product that contains the maximum amount of teaching, so a Teaching Textbook™, with its approximately 700 pages of text and 120-160 hours of teacher instruction, is both a teacher and a textbook combined into one. And the teaching isn’t just abstract lectures either, it introduces proper terminology only after first presenting the underlying concept in plain language. Of course, the series includes all the terms that students need to know for important standardized tests such as the SAT and ACT, but our textbooks do not bog the reader down in highly technical language until students are ready to digest it. There are also down-to-earth, audiovisual step-by-step explanations for every single one of the almost 3,500 problems in the book. Using a Teaching Textbook™ is like having a friendly tutor available at the push of a button, but for only a fraction of the cost! Given the amount of teaching that the series offers and the importance of junior high and high school math in college courses and on the job, our program represents an incredible value. For example, the Algebra 1, Algebra 2, Geometry, and Pre-Calculus Teaching Textbooks™ contain far more multimedia teaching than the nearest competitors’ products.
