The Early Childhood Program (ages 3 - 5) is intended to ensure that a child's first exposure to school is a positive and happy one. The curriculum is one that captures the natural curiosity of this age group. In a specially designed space, early childhood students explore numbers and patterns, discovering ways in which numbers are a part of our daily lives (recipes, prices, ages); sing songs and recite poems; listen to stories and "write" their own by dictating their thoughts and ideas to teachers; begin to recognize letters and numbers in print; build with manipulative blocks; notice the fascinating properties of magnets; create using paints, clay, paper, pencils, and crayons; and begin the transition from parallel play to cooperative play.

The children play outdoors each day on the lower school playground, on the climbing equipment and slides and in the sandbox, or around the yard—raking leaves in the fall, digging in the snow in the winter, or chasing butterflies in the spring. They visit the library once a week for story time, and join the older Lower School students in Pachanga.
