School Notes

  • Education at LMS is based on the theories and work of Maria Montessori. This child- centered approach views the primary task of education as allowing children to discover knowledge--and ultimately, themselves--by engaging in meaningful, self-directed activity in a stimulating and nurturing atmosphere. The aim is to help children grow socially, emotionally, cognitively, aesthetically, and physically while also developing self-awareness and an understanding of themselves as members of the world community. We view children as active participants in their learning. Children discover for themselves how to use their intellects and temperaments, how to see and understand and remember. By working to master the carefully prepared classroom environment--both individually and in concert with other students--the children develop the concentration, self-confidence, independence, and self-discipline that will enable them to become life-long learners and problem solvers.

My three kids have been attending Lexington Montessori School since 2018. Our family loves the school and all three kids are happy there. From the access to nineteen acres of outdoor space to the responsive, organized administration to the wealth of diverse and engaged families, there is a lot I could cover in this review. The most important thing for our family, though, is the careful and individualized attention that the experienced faculty give to each of our children. Our toddler learns Spanish, build with blocks, and sorts colors. Our kindergartener grows radishes, skip counts by nine to the cube of nine, and reads to her teacher. Our second grader comes home everyday excited about new writing lessons, learning Chinese from his friend at lunchtime, and building forts in the woods. Our family couldn`t be happier with the school and we are planning to stay there for as long as we can, which is currently through eighth grade. We can always hope that they build a high school soon!

My daughter has been here since Kindergarten, she is a typical learner, excels in math and sciences and has thrived beyond expectations! She is driven, skilled, and motivated, gets papers published, speaks publicly, and accesses her musical and mathematical abilities daily. Yet wants to know how help track the Covid spread and level the field in matters of soci economic diversity while honing her Spanish fluency. This was all cultivated in the playground of Lexington Montessori School. The way this school allows her to be her, despite my wishes is amazing! They honor the child in ways old fashioned systems did long ago when education was an art form and honored for its importance. They have a detailed long-range plan, not one based in immediate gratification. My daughter has had active role, in the direction of her educational design. This is what has made her accountable, not I. Her academics are not memorized or rote, they are learned, she adores school, and her classmates! Small classes equal rigor, her Math and English teachers in the middle school do not let her get away with anything! Nicely they ask her to meet deadlines, as she has individual and group work to be accountable for. Her Spanish teacher gave her extra books to read during the pandemic to assist in the summer program so she can be part of the solution in the community. The Farming teacher encouraged her and her classmates harvest crop during summer months safety, creatively to again solve practical useful challenges that need attention. Then her science teacher, who happens to be her advisor to the entire day`s regular outdoor classroom, quietly, humbly is aware of every step she makes. She does not say much but helps her stay on track when she veers off in one direction that may not be consistent with goals they developed to meet. The cohesive team is so well integrated I cannot say enough about LMS, Kim, GM, Kate and AMY. Hard year for most, yes, this school is amazing not just this year every year but especially this year. While so many families are struggling my child thrives and grows in sunlight. Each student at LMS has an outdoor classroom, has access to 19 acres of land, to students and parents who are taking active roles in deep learning from foundational skills to testing skills. Middle School is a parent`s dream. My child is pushed internally and as any educator knows getting to these skills is hard, but not for Lexington Montessori. Bravo, well done!

We moved both our boys (grades 3 and 6) from Lexington Public Schools to Lexington Montessori this year and couldn't be happier! Everyone we've met at LMS, from faculty to parents and students, has been so welcoming. From the very first day of school, the boys said they love LMS. They look forward to schooling each morning, and they even ask us to take them there on weekends so they can show us around the amazing 19 acres of woods, wetlands, and stream. The class sizes are especially small this year because of Covid precautions, and the kids spend half the day in the newly built tents to maximize time outdoors. My kids are learning so much academically, socially, and physically. They love the freedom they have to climb trees and pick up rocks, when in public school there were just so many rules. They're loving that their teachers really get to know them and talk with them. They're loving all the new things they're learning and the new friends they're making. And most of all, we're all loving the sense of normalcy LMS brought back to our lives with real in-person school every day. I'm so glad we joined LMS!

Lexington Montessori School (LMS) is a truly amazing place. The school has helped my three children become confident learners. They truly love coming to school - even my middle schooler! Teachers create a safe environment where my kids feel respected and appropriately challenged. There are a lot of good schools out there but LMS is a unique community of teachers and administrators dedicated to continually looking for ways to enrich my children's learning experiences.

The Lexington Montessori School (LMS) is a truly wonderful school! Having had two very different children attend from pre-school through 8th grade, I can attest to the school’s excellent academics as well as its emphasis on educating the “whole” child. In the hands of caring teachers, my children blossomed intellectually, emotionally, and socially. They each graduated with a strong sense of self, an appreciation for their individual learning styles, and an understanding of their place in this vibrant community. I am grateful to this school for 1) its emphasis on critical thinking and creative problem-solving. Both my children attend a rigorous private high school where their teachers have noted with admiration their analytical and problem-solving skills. 2) its diversity. 48% of the students at LMS are children of color and 40% of the teachers are people of color. My children will be operating in a multi-cultural world and I am grateful that they grew up respecting different ethnicities and religions in this diverse school environment. 3) its focus on sustainability. In weaving environmental and social sustainability into the curriculum, LMS taught my kids about stewardship of the earth and the impact that their actions can have on the planet and others. 4) its strong sense of community. LMS is a caring community where my children learned tolerance and respect for others. They learned to collaborate and to resolve conflicts. They have formed deep and lasting connections with classmates and teachers.

Both my children are LMS students and have been for eight years now. They both have very different learning styles and the curriculum, philosophy and support of the teachers have served them both well. They are now independent learners, who know their weaknesses and strengths and take charge of their own learning. They are also very respectful people who understand their place in a community. They see themselves as a important, but yet one, piece of a bigger entity. They care for others and want to do well. They also love going to school everyday. We are happy to have found LMS.
