Oregon Educational Publishing specializes in materials designed to help middle and high school students prepare for their state's standardized mathematics test. Teachers can use these materials to supplement a regular math class, or as the basis for a "test prep" course. Lessons and exercises are written in a simple "friendly" style that students (and their parents!) can understand and use on their own for self-directed study.
