The Aspen Country Day journey begins! The PreK Three class is for children who are two and a half by September 1 of the school year. The PreK Four classroom is for children who are age 4 by September 1. The nurturing, friendly atmosphere emphasizes play as the children's most meaningful work.

Western Colorado's highest-rated PreKindergarten program

Lively, happy days

Children enjoy a balance of hands-on exploration and group instruction with loving teachers and friendly classmates.

Small class sizes

PreKindergarten Three has 14 students per day. PreKindergarten Four has 18 students per day. Children can come two, three, four, or five days per week. 

Teachers who know and care for each child

Each age group has its own classroom with a certified director and two additional experienced teachers, giving the PreKindergartners a student-to-teacher ratio of six-to-one.

An enriching curriculum

Unique in the Roaring Fork Valley, Aspen Country Day School PreKindergarten offers instruction in French and Spanish, visual arts, performing arts, and physical education. Our school-wide curriculum starts with PreKindergarten Three and builds progressively each year through Eighth Grade.

A guaranteed spot for future grades

In a school where many classes fill quickly and waiting lists are not uncommon, current PreKindergarten students have first priority in enrollment for the grades that follow. 

A friendly school family

PreKindergartners love being part of a “real school” and belonging to a community of learners. They are the darlings of the campus, making friends with older children through the Buddy Grade program, at recess, and in the all-school play at the Wheeler Opera House. 

Convenient school day

The program runs from the beginning of September through May, and the hours are the same as all the grades: 8 am to 3:10 pm M, T, Th, F; 8-2 on Wednesdays.

Complete pricing

Cocurricular classes, bus service, field trips, snacks and a nutritious, family-style hot lunch are all included in tuition.

All about the program

Exploring themes

A world of learning opens

The Aspen Country Day School PreKindergarten program is a theme-based model that emphasizes the importance of play; being immersed in spoken and written language; developing the ability to share objects as well as ideas; and creating through imaginative play. Social/emotional skills are a main focus. Nurturing teachers help children adjust to the school environment and to being away from home. Children develop friendship skills, self-help skills, and independence. Examples of themes are "all about me," "getting along with others," or "nature all around us." Through the themes, students are exposed to literacy, social studies, math, science, music, art, and world languages.

Language Arts

Finding your voice

Speaking, listening, and using your imagination are the building blocks of language arts. Our youngest students are introduced to more formal listening/speaking exchanges through circle time, read aloud, songs, etc. Children find their voice through their own storytelling, expressing ideas or needs, and role playing. Gradually, students connect speaking and writing by dictating their ideas to their teachers. Letter recognition and formation are gently introduced in PreK Three. The sound/symbol connection is developed in PreK Four, where we use the Letter People curriculum. See all Language Arts


Beginning number sense

We begin with experientially based exposure to numbers, counting, and number concepts. Emphasis is placed on tangible learning techniques through daily exposure to manipulatives, finger plays, and small-group math activities. Children develop a basic awareness of numbers, explore the concept of 1-to-1 correspondence, investigate sorting, measuring, graphing, patterns, and shapes. They begin to match quanitities to numbers, laying the foundation for future math study. See all Mathematics

Social Studies


The focus of Social Studies in the primary grades is to develop an understanding of how individuals make up communities and societies. Exploring the groups to which children naturally belong (family, class, school etc.,) students begin to see that they are part of a greater whole -- their community -- and that the community is part of a greater society. We explore many holidays and traditions. See all Social Studies


Inquiring minds

Each PreK classroom has a science interest area which helps children develop scientific intelligence through observation, inquiry, investigation and their own natural curiosity. One of the favorite activities of the PreKindergarten classes is joining their buddy grades to witness a science experiment put on by Middle School students and teachers. There are also plenty of hands-on outdoor experiments, such as measuring snowfall with a yardstick on the playground, observing a family of goslings on the pond, or taking field trips to nearby nature centers. See all Science

French and Spanish

Two languages to explore

Students are exposed to a semester of each language three times per week. Working with their own classroom teachers in PreK Three and with ACDS World Language teachers in PreK Four, they learn games, songs, creative arts and activities that build their pronunciation and listening skills. They learn numbers, colors, animals, greetings, and parts of the body. Starting in First Grade, students choose French or Spanish for continued study throughout their Country Day journey. See all World Language

Outdoor & Physical Education

Games and fresh air

Children have recess and lots of outdoor play time. They attend special PE classes three times per week. The program focuses on a variety of games to build foundational skills for success in later sports activities. Children develop their loco-motor skills and spatial awareness. They practice manipulative skills (rolling, tossing catching, kicking) and play cooperative games. Students begin to understand how activity keeps us healthy. See all Outdoor Education

Performing Arts

On stage 

Country Day has long been recognized for the strength of its Performing Arts program. Children learn to sing, dance, perform, and play basic instruments.  They perform in the annual Holiday Sing, All-School Play, and special PreK performances. These on-stage opportunities give them confidence and poise as well as a rich understanding of theater and music. See all Drama

Visual Arts

Masterworks & more

The arts are an integral part of education and of life at Country Day. Each classroom includes a rich art center so the children can express creativity and explore different mediums. Classroom teachers lead guided art activities throughout the year. The children bring home many wonderful creations, which are also displayed in the hallways outside the classroom. See all Visual Arts

PreK atmosphere

appreciating each other

Since socialization is so important at this age level, we focus on learning love and respect. The school's motto, de amicitia, means "in the spirit of friendship." The Aspen Country Day community has always been about nurturing children in a school family where each person looks out for and cares for others. This atmosphere of respect and appreciation of each other inspires our Buddy Grade program, where older children are matched up with younger ones for fun activities throughout the year. PreK children build a special connection with older students and adults all across the campus.
