School of Grammar


In the classical model we follow at ACA, the elementary years, known as Grammar School, are, quite literally, foundational. These are the years when children learn the facts and fundamentals, (aka “grammars”) of language, critical thinking, and knowledge acquisition.

Children are natural learners and have a curiosity about the world in which they live. They delight in finding out how the world works, and in the School of Grammar, we train them to explore the world and master the basic fundamentals to build their knowledge and thinking skills.  The classical approach recognizes that children learn through interaction with and discovery of the world around them, and that at this age they can learn quickly when given the right tools and the right environment, one that fosters their natural curiosity while giving them enough structure to make sense of it all.

Since God is sovereign and ever working, we teach our students to consistently return to God’s Word as the foundation for their exploration of God’s world (Psalm 119:11, Job 28:28). Hands-on experiential knowledge is augmented with careful study of the absolute truth of Scripture and investigation of history, English, classical languages, geography, science, and math that result in “scientia et delectatio,” or knowledge and delight.

Imagine a school where your child can...

GROW in Knowledge

DELIGHT in Learning

WONDER at God's Creation 

Our motto for Grammar School is wonder and delight because we know that it is a wonderful thing as students are introduced to the world around them and delight in becoming more knowledgeable about it. Some of the ways we help develop wonder and delight include: 

  • Integrated curriculum with themes that unify literature, history, science, art, and music. As an example, 2nd graders build miniature tabernacles out of clay to connect the Bible to ancient history through the medium of art. This is a distinct value of classical education compared to traditional or “modern” education.
  • Broad-based use of story, song, rhyme, rhythm, memorization, and recitation to make learning fundamentals fun and engage all learning modalities.
  • Ongoing mentorship program with secondary students that truly demonstrates our family atmosphere. It’s not unusual to find a high school student reading to a kindergartener or Grammar students joining the high school Biology class as they dissect fish. This is intentional and unlike anything else, anywhere else!
  • Early introduction of Latin to help students develop a sense of the universal consistencies of language construction. These early language lessons are designed to be engaging for young minds with something like the Latin conjugation of “Amo, amas, amat” (I love, you love; he, she, or it loves) being taught as a chant or a rhyme.
