PRECALCULUS/DMACC MAT 129

Urbandale High School Syllabus

Description of Course

Precalculus is a course designed to match the AP (College Board) goals and objectives. The goal is to provide students with the good critical-thinking skills needed to succeed in any endeavor. Algebraic, numerical, and graphical representations are emphasized throughout the course.

Five hours of DMACC credit is available for Precalculus because the course is taught to meet the DMACC curriculum/competencies. This will be offered in the second semester.
