Mathematics Department Mission Statement

The Mathematics Department at Brophy College Preparatory is committed to the belief that all creation is a reflection of God’s love and presence which demands a passionate and generous response from the entire community. By creating an atmosphere for academic, emotional and spiritual growth, the Math Department develops critically thinking, articulate, sensitive and aware students with a strong sense of self-worth and a desire to do justice in their community.

The mathematics curriculum of Brophy is designed to support the growth of an Ignatian student. After four years, each student should exhibit the expected learning outcomes for a student attending a Jesuit high school. These include being open to growth, intellectually competent, religious, loving and committed to doing justice. Each of these outcomes is addressed within the mathematics curriculum at Brophy, with a particular emphasis on openness to growth and intellectual competence.
