Math Info & Syllabus

Welcome! This is the sixth year our middle school students will be taught and assessed by the Common Core Math Standards.  Under the Connected Math Project (CMP), students will receive a rigorous Common Core curriculum that focuses on problem solving, understanding concepts, and proportional reasoning.  This program is designed to empower students to think, generate new ideas, and enhance their communication skills. The approach to this process is frequent collaboration that will strengthen our students as a whole as well as improve student's individual knowledge and success in our society.
