Early Childhood

Ages Two Through KindergartenEarly Childhood

At the Primary Grade Center, our youngest students step into a world built for discovery. From age two through kindergarten, children learn best through play, exploration, and the steady guidance of teachers who understand that the earliest years shape everything that follows.

Every Early Childhood classroom pairs a certified teacher with a trained teaching assistant, so each child receives the attention, encouragement, and care that build confidence.  A multi-sensory, theme-based curriculum develops the whole child: motor skills, language, social-emotional growth, and a love of learning, within a loving Catholic community that knows each child by name.
Where the youngest Crusaders learn through play, wonder, and faith.

More Than a Day, a Foundation

Families who come to us from a daycare setting often notice the difference within a single visit. Here, play has purpose. Each day unfolds with intention, building language, motor skills, and social confidence through centers, music, art, and conversation. 

Routine teaches responsibility. Circle time teaches listening. Friendships teach kindness. What looks like joyful play is, in fact, the careful work of getting ready for kindergarten and for everything that follows. Children leave each day a little more capable, a little more curious, and a little more themselves.
