An elementary classroom at Polis World School in Manhattan

Your elementary-aged child uses the materials and activities of the classroom as a window to the world. Her developing imagination gives her the ability to visualize the distant past, the far reaches of the universe, and the tiniest particle of matter.

The materials in the classroom spark that imagination and inspire her to plan outings, initiate research projects, and delve deep into literature, science, and history.

Computers used in the Polis elementary environment

The elementary child's mind gradually develops the ability to abstract complex ideas, so over time your child will work less with the concrete materials and more with conceptual ideas.

A cozy reading nook for Polis elementary Montessori students

Your child's classroom always offers a special place for your child to cozy up with a good book or some contextual reading for a research project.

    English Lead Guide, Children's House

    Esther Chae moved to New York City from Toronto, Canada. She studied Life Science and minored in Psychology at McMaster University, and proceeded to teach English as a second language for five years in Seoul while traveling Asia in her spare time.

    While teaching in Seoul, Esther saw the limitations of traditional education and questioned what approach to education would most benefit the children. She ultimately discovered the Montessori method, which confirmed what she had observed about how children naturally develop and learn. Inspired by Dr. Montessori's scientific approach to education, Esther pursued further studies at the Foundation for Montessori Education in Toronto, an Association Montessori International accredited foundation founded by Renilde Montessori.

    Esther is a strong believer in the role of community as a vital support system for the child. She is confident that with the proper awareness of childhood development in our society, we can all play a role in bringing forth a bright generation of children who are prepared to succeed at anything to which they put their minds.

    In Esther's spare time, she loves to cook because she knows that food brings people together and that the best conversations begin over a good meal. Predictably, Esther's role model is Chef Julia Child, who brought French cuisine into the American kitchen and was a beautiful example of how Montessori leads to social, emotional, and professional success.

A Q&A with Ms. Demko

  • What most excites you about Polis World School?

  • It's rare for a school to take full advantage of the environment outside the school building. The city will be our campus, a remarkable opportunity not accessed by most schools. Immersing our students in the cultural richness of New York City is instrumental to their learning experience. The Art Tours that we hosted at the Metropolitan Museum of Art also concretized for me the vast opportunities that this city in particular affords our students to learn history, design, art, and all other critical elements of a classical education.

    Additionally, I am deeply impressed by Polis World School's commitment to providing an authentic Montessori experience. We hire only AMI certified and trained teachers who are dual speakers, with Mandarin as their native language. The quality of instruction our students receive will be top-notch, and I love that our curriculum will impart 21st century skills in our students, which are vital in this city. These skills include creativity, creative thinking, collaboration, and communication, all of which have been important components of Montessori education for over 100 years.

    The language component of Polis World School is special to me, as I established a teacher exchange program in Taiwan, with St. James Kindergarten, that is now in its tenth year of operation. I watched as the children in both the U.S. and Taiwan picked up Mandarin and English, respectively, in organic ways that enabled them to communicate with their peers, and I look forward to replicating this natural language learning at Polis World School.

  • What was your experience building a language immersion program?

  • I was director of a preschool that had language immersion programs in Spanish, French, and Mandarin, but it offered language immersion only one afternoon each week. I observed how popular the immersion programs had become with our families, and I approached the Board of Directors about offering the language program five days per week. There were, of course, a few challenges associated with doing that, but in the end, we built the process up and it was immediately enrolled to capacity as I had anticipated.

    Soon after, a teacher approached me to let me know that she had attended a school named St. James Kindergarten as a child herself, and the current Head of School there was interested in building a teacher exchange program. I met with him and we soon turned this vision into reality. Every year, we provided Taiwanese teachers with housing and English language classes in the morning, and in the afternoon, the teachers taught in an immersion setting. In time, St. James found it had long lines of teachers anxiously hoping to be offered the job because our exchange program had become so desired an opportunity for them.

    What struck me most about leading the program is the resilience and courage that people develop when faced with new challenges. I recall one teacher in particular who was very excited all year long to go to Taiwan for the summer, but one month before the trip, confessed that she was terrified of flying and had never been on an airplane before. We spent that month working together and preparing for the trip, and she persevered through her personal battles, got on that plane, and went. Over the ten years during which I ran this program, I saw so many experiences like that. It is this ability to rise to any occasion that I believe the Polis World School curriculum and approach will help to develop in our students.

  • What is your favorite Montessori moment?

  • When I was interviewing for my first Head of School position at a Montessori school, I was required to visit and observe one of their classrooms. I was asked to sit in the observation chair and not engage with the students, but instead to simply watch them. I was doing so quietly when I noticed a five-year-old child doing multiplication with four digits. I was watching him as he used the math materials and wrote these very large numbers. I thought this was quite silly because in my outside work as a teacher up until that time, I had known such multiplication to be third grade curriculum not at all appropriate for a five-year-old. I couldn’t resist rising from my chair to speak with the child about what he was working on. I still remember: he was multiplying 2,456 by 3. I watched him do the operation of multiplying that long number by three, and said to myself that such a young child couldn’t possibly understand the concept of place valu —and yet to my great surprise, he could build the number and completed the problem to get the right product.

    That moment showed me that I had been underestimating children for twenty years. I was offered the job and gladly accepted, and then I was immediately sent to receive my AMI training. I never turned back, grateful to have discovered the key to educational success.

  • What are some things you are excited for Polis World School students to do in New York City?

  • Just moving into my apartment in the Upper East Side last Wednesday made me aware that the neighborhoods of Manhattan provide unlimited potential for discovery, exploration, and learning. On my walk to the grocery store to pick up my essentials for my first morning in Manhattan (coffee, cream, and bagels) I saw a 100 year-old dollhouse store, an award-winning French bakery, and a vintage art dealer. I envisioned the learning experiences that our Polis students could have.

    Dollhouse miniatures are used extensively for vocabulary building in Montessori classrooms for many reasons. Children love all things tiny, and are drawn to the intricate details. They learn vocabulary, spelling, and parts of speech through these beautiful objects. Imagine the children entering this store and choosing what to purchase for the classroom by using Mandarin, when literally every surface of the shop is occupied!

    We are going to bring our children out to experience real-life activities such as bread making, and why not learn from the experts! Preparing for a bakery visit by drafting a list of questions for the artisans and deciding what kind of transportation will be most efficient helps the children become invested and engaged even before they enter the bread shop. Slicing and taste testing different kinds of French bread with classmates captures their attention further. While on-site, listening to the master bakers talk about the science, math, as well as the art of the craft of bread-baking surrounded by the smells of the shop, our students will have a deeper appreciation for something they may eat each day. Polis field trips will be unique in that students will get their hands dirty kneading dough or crimping dumplings.

    Around Manhattan, our students will visit some of the most famous works of art in the world, as some have already, at the Metropolitan Museum of Art. However, we will also visit local businesses like the art dealer on the corner! Just passing by the window, I have questions: What do you collect and buy? How do you price the art? How old are some of your paintings? Are you an artist yourself? At Polis, we want to encourage children to be generative with their questions and active in their learning, and so we will be providing them with authentic access to the city.

    Finally, our Polis parents will also share with our students the experiences and expertise that they possess to enrich the fabric of our school community. While I was getting a lift uptown from a Polis parent, she shared stories of her elementary school education in Manhattan. Our parents seek a difference for their children… they crave authentic learning experiences where their children can not only become literate in two languages, but also become active participants in learning through exploration and discovery.
