Our arithmetic
course is designed to help a teacher show that arithmetic is more than a set of rules. Just as a coach explains and interprets
the rules for the players, teachers also are coaches who interpret and explain the rules of arithmetic to their students.
We are convinced that the rules of arithmetic are based on treating numbers as adjectives that modify nouns. Using this
rule as the foundation for arithmetic, students soon learn that they understand mathematics better than they thought they
did. The adjective noun theme unifies whole numbers, fractions, decimals and signed numbers
by means of a seamless transition. Of equal importance the adjective noun theme gives you, the teacher,
a tool for implementing your own style and delivery system. Learning it does not require you to change
anything else you do as a teacher.

Our algebra course is designed to combat students' misconception
that a calculator is all they need to solve any arithmetic problem. In fact, our algebra course is based on using the
basic rules of arithmetic to paraphrase problems that can’t be solved with a calculator into equivalent problems that
can be solved by using the calculator.
