There are numerous resources available online, primarily from the United States Conference of Catholic Bishops and writings of recent popes to help you not only facilitate your classroom discussion regarding the complementary nature of the sacraments, but also to contribute to your own knowledge about the sacramental life. Whether or not you teach a particular course on the Seven Sacraments, these readings can contribute to a foundational source essential for a curriculum with a Christological focus.
These following referenced sources can also be assigned to your students, either in their entirety, or in a validly excerpted fashion, depending on the scope of your course. At least one resource is listed for each sacrament. You are encouraged to seek more worthwhile resources that similarly portray the Seven Sacraments accurately and objectively.
