ResourceMAP - Basic Algebra - Student Edition (Spanish)

ResourceMAP modules are relatively short and designed for flexible implementation; that is, they can be used in regular classes as well as in special test-preparation settings. Each module contains a set of contextual problems in several formats: multi-part open response, short response, and multiple-choice. Accompanying the problem set are tip sheets that serve several purposes including lists of formulas, calculator instruction, and brief reviews of the module's underlying mathematics. Also provided are teacher notes (the module purpose, the mathematical focus, and implementation commentary), answers to all problems, and (in a few cases) handout masters.

Basic Algebra

Many people use formulas. Formulas and the way they work are a big part of basic
algebra. A formula is an equation that describes the way two or more variables are
related. (A variable is a quantity that changes; that is, it takes on different values.)
The simplest formulas describe how two variables are related and involve only basic
calculations: adding, subtracting, multiplying, or dividing.
