OUR CARING TEACHERS WILL HELP YOUR CHILD DEVELOP A LOVE OF LEARNING
The lower school curriculum includes daily experiences in language arts, mathematics, and social studies. Students attend a media center class once per week, science, modern languages, art, and music/drama classes two to three times per week, and physical education classes two or three times per week.
The lower school provides opportunities for children to develop academically, emotionally, socially, and physically. High and consistent standards promote student responsibility for the development of a positive self-image and the realization of each child’s intellectual, physical, social, emotional, and creative potential. Through shared standards and open communication, parents are engaged as partners in this process.
Students are actively engaged in the learning process through experiences that promote analytical and critical thinking, risk taking, investigation, individual creativity, cooperation, and collaboration. We encourage students to develop a strong work ethic and the ability to work independently. The faculty uses a variety of instructional strategies to overcome weaknesses and build on strengths.
The lower school teaches children compassion for others, as well as appreciation of differences among people; a high value is placed on character education and multicultural understanding. Daily, whole-school discussions revolve around our character traits. Through careful attention to the whole child, the faculty and staff strive to produce academically well-prepared graduates who are thoughtful, motivated, productive, and self-confident young people.
Ask any CIS family, and they’ll tell you the quality and dedication of our teachers is what sets us apart from other schools. They give individual attention to every student and are truly invested in their success.
