As the educational needs of children continue to expand during the elementary school years, the curriculum grows increasingly complex, allowing students to explore subjects more fully, ask new questions, and build critical thinking skills.

All students are assigned to a homeroom teacher, with whom they spend most of the school day. Every teacher at Cornerstone is certified by the Board of Education, meaning that they are qualified to attend to the social, emotional, and intellectual needs of students in their grade level. Homeroom teachers are responsible for grading and parental questions.

Homeroom instruction is supplemented by time in music, visual art, Spanish, and physical education classes.

Phonics (K5-2)
Students in grades K5-2 continue to develop phonemic awareness, phonics, and vocabulary through the Wright Skills curriculum. Children learn to hear and manipulate sounds, an essential skill for learning to read in an alphabetic writing system. The program provides opportunities to develop fluency and comprehension by its systematic skills instruction that introduces key concepts that build on one another. Wright Skills also teaches spelling and writing, oral language development, print awareness, and alphabet knowledge.

Reading
For students in grades K5-6, Cornerstone employs the Foundations and Frameworks curriculum. Foundations and Frameworks is an instructional reading program that uses a collection of best institutional practices for equipping students to fully understand ideas conveyed in a text. Critical thinking skills, necessary for the thorough comprehension of a text, are explicitly taught and modeled. By breaking thinking down into its component steps, teaching these steps explicitly, and extensively modeling the use of these steps, teachers can equip students with the cognitive abilities needed to fully understand a text.

Mathematics
The elementary school math curriculum is based on the Everyday Mathematics program, produced through the research of the University of Chicago School Mathematics Project. Everyday Math builds from the basics in elementary school and continues through fifth grade, at which point students are beginning to engage in the higher-order thinking necessary for advanced work in geometry, calculus, and physics. By laying the foundation of the curriculum early, mathematical thinking becomes a natural process and a part of everyday life because it is instilled in a systematized, continuous manner.

Science
Cornerstone uses the FOSS (Full Option Science System) science curriculum, which was developed at the University of California, Berkeley. FOSS program materials, which align with Alabama and national standards, are designed to meet the challenge of providing meaningful science education for all students in diverse classrooms, bringing them into frequent interaction with the activity of scientific inquiry. Students build critical thinking skills through science as well, and enrichment is provided through a partnership with the Junior League of Birmingham.

Social Studies
Though the focus differs for each grade, the goal of social studies is to build awareness of culture, history, and geography – both physical and demographic. As writers and critical thinkers more closely connected to history, students will be able to understand their own society more clearly and analyze it more effectively.

Bible
Elementary school students read the Bible every day during class and learn mostly through its narratives, which present them with circumstances and issues that they will encounter in their own lives. The curriculum is based the ACSI (Association of Christian Schools International) Bible curriculum, but students are taught to take away more than just knowledge from their interaction with scripture. At Cornerstone, teachers make scripture deeply relevant to the students' lives to serve as a foundation upon which they can face difficulties and questions. Furthermore, teachers ensure that biblical principles are communicated in all of the other subjects, recognizing the fact that learning is a process of uncovering God's glory.
