Our forest school philosophy, explained

Why We Play

For over fifteen years, Big Tree Little Preschool has been a play-based, screen-free forest school on five acres in Vista, serving families across North County San Diego. We blend the forest school philosophy with the Reggio Emilia approach — and if you're new to forest school philosophy, this page answers the questions parents ask us most.

How children learn at Big Tree

Young children learn by doing. Our days revolve around outdoor play, hands-on projects, and collaborative discovery: gardens, nature walks, art from found materials, climbing, water play, music, and unhurried time under the big tree. Rain is a curriculum, not a cancellation.

Our teachers watch what captures the children's curiosity and build learning from it — a practice called emergent curriculum. A puddle becomes a lesson in volume. An acorn collection becomes counting, sorting, and sharing. A ladybug becomes a week of questions about how living things grow.

Play is not a break from learning. For children ages two through five, play is how the brain builds language, mathematical thinking, self-control, and social skill — so our curriculum weaves reading, writing, and math readiness through art, music, movement, science, and nature all day long

Will my child be ready for kindergarten?

Yes — and this is the question we love most. Decades of research are consistent: pushing formal academics in preschool produces short-term gains in memorized skills, while the abilities tied to long-term school success — vocabulary, reasoning, curiosity, persistence, self-regulation — grow best through rich play and conversation. Children from strong play-based programs enter kindergarten socially confident, emotionally regulated, and ready to learn.

Our graduates walk into kindergarten confident, curious, and ready. Counting happens with acorns; early literacy happens in story circles under the big tree; science happens in the garden with watering cans. Readiness isn't rushed here — it's grown. And because our groups are small, teachers know exactly where each child is and gently stretch them further

How is Big Tree different from Montessori?

Families arriving from Montessori programs often love Big Tree — the two approaches share deep respect for the child, hands-on materials, and confidence in children's independence. The honest difference is where the structure lives. Montessori structures learning through a carefully sequenced set of indoor materials, each designed to teach a specific skill. Big Tree structures learning through the rhythm of the day and the natural world, with open-ended materials — mud, water, logs, gardens, art supplies — that children use in endlessly inventive ways, guided by teachers who extend each child's thinking.

Neither approach is "more educational." A child who thrives on order and quiet mastery may love Montessori's materials. A child who thrives on movement, nature, imagination, and open ended discovery — or who simply needs room to be two, three, or four — tends to flourish here. Many of our families tried both and chose the trees

Will my child get dirty?

Wonderfully, yes. Muddy knees, sandy shoes, paint on sleeves — we consider this evidence of a day well spent. Messy, sensory play builds fine-motor strength, scientific thinking, and comfort in the child's own body, and time in soil and nature supports healthy immune development. Dress your child in sturdy play clothes, send a change of clothes, and save the special outfits for special occasions. We handle the learning; the washing machine handles the rest.

What about scrapes and climbing? Is it safe?

We believe children grow in confidence through safe, challenging play — balancing on logs, climbing a little way up a tree, running on uneven ground. Researchers call this supervised risky play, and it's one of the best-documented ways children learn to judge risk, build resilience, and trust their own bodies.

Here's how we keep it safe: our teachers supervise closely and check the play spaces and trails before children explore; children learn the safety rules of the preserve and stay with the group; and firm limits protect against real hazards — our staff are trained to know the difference between a wobbly log and an actual danger. When a minor scrape happens, it gets a cleaning, a bandaid, and a hug — and you get a note the same day. Anything beyond minor gets a phone call, every time. 

Is a play-based day structured?

Yes — play-based does not mean chaos. Our days follow a strong, predictable rhythm: arrival, morning circle, outdoor exploration, snack, project time, lunch, rest, afternoon play. Children thrive on knowing what comes next. Within that rhythm, children choose much of their own play; alongside it, teachers lead group activities, stories, music, and projects every day. One of our parents called it "the strong but flexible structure of the day and the rhythms of the week." That's the design: enough structure to feel safe, enough freedom to wonder.

Come see it

A morning on our five acres explains Big Tree better than any web page. Book a tour, bring your questions — especially the skeptical ones — and watch the children work. We think you'll see what fifteen years of Vista families have seen: children who are busy, capable, curious, muddy, and deeply happy.
