Our Mission

Working to build on the current math skills students have acquired, our mathematics department will increase student understanding of mathematical concepts and practical application. Students can choose from courses in Algebra, Geometry, Pre-Calculus, or Consumer Math. Students be encouraged in cooperative work and communication skills so as to be respectful of each other and have fun learning.
