The preschool years are a period of extraordinary brain growth. According to the Center on the Developing Child at Harvard University, more than a million new neural connections form every second in the first years of life, and the connections a child uses most are the ones that get strengthened. Preschool matters because it gives three- and four-year-olds daily, varied experiences – conversation, play, problem-solving, movement, and relationships with caring adults – that put those connections to work.
Here is how a good preschool supports brain development, and what you can look for when choosing a program.
1. Serve-and-Return Conversations Build Language
Researchers describe the back-and-forth between a child and an adult – the child points or asks, the adult responds – as “serve and return.” These exchanges are one of the strongest drivers of early brain development. In preschool, teachers talk with children all day: during circle time, meals, play, and story reading. They introduce new words, ask open questions, and give children time to answer. That steady stream of conversation grows vocabulary and the listening and speaking skills that later support reading.
2. Play Strengthens Executive Function
Executive function – working memory, flexible thinking, and self-control – is the brain’s “air traffic control” system. Preschoolers practice it constantly: remembering the rules of a game, switching roles in pretend play, waiting for a turn, or finding another way when a tower falls. Structured games such as “Simon Says” or freeze dance are simple, fun ways to train impulse control.
3. Hands-On Activities Develop Fine Motor Skills
Cutting with scissors, stringing beads, painting, pouring water, and molding clay strengthen the small muscles of the hands and the hand-eye coordination children need for holding a pencil. These skills develop through repetition, and preschool provides many short, playful chances to practice every day.
4. Movement Supports Focus and Learning Readiness
Young children learn with their whole bodies. Running, climbing, balancing, and crossing the midline of the body support coordination and body awareness and help children settle and focus when it is time for quieter work. That is why active play and movement breaks belong in every preschool day.
5. Friendships Build Social and Emotional Skills
Preschool is often a child’s first experience of being part of a group. Sharing materials, joining a game, handling disappointment, and noticing a friend’s feelings all build the social-emotional skills that predict success in kindergarten. Teachers help by naming emotions, modeling calm problem-solving, and guiding children through conflicts instead of simply ending them.
6. Curiosity and Early Math and Science
Counting snacks, comparing which cup holds more water, sorting leaves, or watching a seed sprout are early math and science. When teachers ask “What do you notice?” or “What do you think will happen?”, children learn to observe, predict, and test ideas – the foundation of later STEM learning.
7. Music and the Arts
Singing, rhythm games, and movement to music support memory, listening, and coordination, and art projects let children plan, experiment, and express ideas. These are not extras; they are part of how young brains connect learning across different areas.
What This Looks Like at Fantasy Island Schools for Kids
Our preschool for ages 3-4 is built around this kind of active, experiential learning:
- A gifted curriculum covering literacy, math, science, social studies, and art through hands-on projects in small classes.
- Brain Gym twice a week, led by our founder Beata Bielic, a certified Brain Gym instructor, with movement exercises such as crossing the midline, balance, and coordination tasks.
- Weekly music classes with a qualified music teacher, plus dance, art, and STEM activities.
- A multi-sensory play space and an outdoor playground.
- Three meals a day cooked on-site, because well-fed children learn better.
- Teachers with Early Childhood Education certifications, First Aid and CPR training. Instruction is in English, with Polish and Ukrainian language support.
Families from Gladstone Park, Norwood Park, Jefferson Park, and nearby communities choose our school at 6100 N Milwaukee Ave for this balance of rich learning and caring routines.
How to Support Brain Development at Home
- Talk and read together every day, and let your child lead the conversation.
- Offer open-ended toys – blocks, art supplies, dress-up clothes – rather than screens.
- Play simple rule games that require waiting, remembering, and switching.
- Keep regular sleep, meal, and play routines.
- Get outside and move together.
Frequently Asked Questions
What is the best age to start preschool?
Most children start between ages 3 and 4. At Fantasy Island, children can begin in our daycare program at age 2 and move into preschool when they are ready.
Is preschool only about getting ready for academics?
No. Academic skills matter, but preschool also builds self-control, social skills, language, and motor skills – the foundations children need to learn well in kindergarten and beyond.
How do I know if a preschool supports brain development?
Look for teachers who talk with children (not just at them), hands-on materials, daily active play, music and art, clear routines, and small groups. Our tour guide lists questions worth asking on any visit.
