Head of School
Rhiannon McElwee
Dear Lesley Ellis Community and Friends,
From my very first visit to Lesley Ellis, I felt something extraordinary. The warmth, curiosity, and authenticity of this community were unmistakable, from the bright eyes of students eager to share their ideas, to the faculty and staff who clearly love what they do, to the families who radiate a deep sense of connection and pride. I knew right away that this was a place I would be honored to lead.
Lesley Ellis “walks the walk.” Our mission—where every child is seen, known, and inspired—comes to life every day in classrooms, hallways, playgrounds, and performances. Students are challenged and supported in equal measure. They ask big questions, grapple with complexity, and grow into thoughtful, confident learners who care deeply about the world around them. That combination of intellectual rigor, creativity, and compassion is what makes Lesley Ellis so special.
As I begin my tenure as Head of School, I am filled with gratitude for the strong foundation built by my predecessor, Deanne Benson, and by the talented faculty, staff, and families who make this community thrive. Enrollment is strong, students are flourishing, and the energy on campus is palpable. Together, we’ll continue to nurture that spirit while exploring new ways to strengthen our programs and deepen our shared values.
My goal is to build on the excellence that already defines Lesley Ellis, ensuring that our students continue to experience the joy of discovery, the power of belonging, and the inspiration to make a difference.
On a personal note, my husband, daughter, and I are thrilled to join the Lesley Ellis family and we all thank you for such an accepting and inclusive welcome.
With warmth and excitement for all that lies ahead,
Rhiannon McElwee

The benefit of getting it wrong
October 25, 2026
What If Getting It Wrong Is Part of Getting It Right?
This week, I had the pleasure of observing what I can only describe as a masterclass in mathematics instruction.
The lesson was titled “My Favorite Mistakes and My Favorite Answers,” and it centered on students’ first math assessment of the year. Rather than simply receiving the assessments with grades and corrections, students were given carefully selected examples of student work that offered opportunities for deeper learning. Some illustrated common misconceptions or interesting mistakes, while others showcased particularly thoughtful or creative approaches to solving a problem.
All the examples were anonymized, although students were welcome to claim their work if they wished. What unfolded was a rich, thoughtful, and wonderfully collaborative discussion about mathematics.
Students examined mistakes, considered where the thinking had gone astray, and worked together to understand how to approach the problems differently. They explored their classmates’ solutions, discovering that there can be multiple pathways to the same answer. They explained their reasoning, asked questions, challenged assumptions, and built on one another’s ideas. The mathematical thinking was palpable.
What struck me most was the culture of learning that was intentionally cultivated. Mistakes were not something to be embarrassed about or quietly corrected and forgotten. They were opportunities for everyone to learn. And equally importantly, students were learning that their classmates’ thinking had value, even when it differed from their own.
This is what progressive education looks like when it is both joyful and intellectually rigorous. There is sometimes a misconception that progressive education prioritizes the process of learning at the expense of academic rigor. In fact, the opposite is true. Of course, we want our students to develop strong computational skills, mathematical fluency, and a solid foundation of knowledge. These are essential. But we also want them to go further: to understand why mathematical concepts work, to apply their knowledge in unfamiliar situations, to articulate and defend their reasoning, and to recognize that there may be more than one way to solve a complex problem.
Getting the correct answer matters. Understanding the mathematics behind that answer matters just as much. And there was something else happening in the classroom that extended well beyond mathematics. Students were practicing perspective-taking, intellectual humility, and the courage to take risks. They were learning to listen to one another, to reconsider their own thinking in light of new information, and to see mistakes not as a reflection of their ability but as a natural and necessary part of learning.
These are habits of mind that will serve them long after they have forgotten a particular equation or mathematical procedure. I left the classroom thinking about how powerful it is when students understand that learning is not about always being right. It is about being curious, being willing to wrestle with something difficult, and recognizing that our thinking becomes stronger when we learn alongside others.
That is the kind of mathematician, thinker, and learner we hope every Lesley Ellis student will become. And it was a wonderful reminder that some of the most meaningful learning happens not when we get something right the first time, but when we have the opportunity to figure out why we didn’t.
Warmly, Rhi |

The power of choice: building agency, engagement, and identity
|
In PreK, I visited during Choice Time, when students were moving purposefully between a variety of thoughtfully designed learning experiences. Some were exploring writing, others were threading beads to strengthen their fine motor skills, while another group was immersed in sensory play, combining conditioner and cornstarch to create a wonderfully tactile material (and one that can easily be recreated at home!). To the casual observer, it might simply look like children playing. But beneath the surface, important learning is taking place. Children are making decisions, following their curiosity, developing independence, and learning to take ownership of their experiences. Meanwhile, teachers are circulating, conversing with students, supporting their thinking and documenting their progress for portfolios. |
In Kindergarten, I saw another wonderful example of how choice and intentional instruction work hand in hand. During a writing mini-lesson, all students were learning and practicing the same foundational writing skills, but when it came time to apply those skills, they had the freedom to choose what they wanted to write about. The learning goal was shared, but the pathway to demonstrating that learning was personal. By giving children the opportunity to write about something meaningful to them, we help them see writing not simply as a skill to master, but as a powerful tool for expressing their own ideas and experiences. |
In first grade math, choice looked a little different. Students were working in differentiated groups, with some exploring graphing while others tackled mathematical problems using manipulatives of their choosing. Rather than being told exactly which tools to use, students were encouraged to think about what might help them solve a problem. This is an important distinction. We aren’t simply teaching children how to arrive at the right answer; we’re helping them develop the confidence and flexibility to decide how to approach a challenge.
By middle school, choice takes on new dimensions as students develop a stronger sense of who they are, what interests them, and how they want to express their ideas. 7th grade Historians have been researching and planning their own political platform campaigns addressing a social issue of their choosing and will be creating their own videos. These opportunities invite students to connect their learning to their identities, experiences, and perspectives, making their work both more meaningful and more personal. |
Of course, choice at Lesley Ellis doesn’t mean an absence of structure or expectations. Quite the opposite. Meaningful choice is intentionally designed by teachers, who provide the guidance, scaffolding, and appropriate boundaries that allow students to exercise independence while continuing to grow and be challenged.
Across the grades, the opportunities for choice become increasingly sophisticated, but the underlying purpose remains the same. When students have a voice in their learning, they are more engaged, more invested, and more willing to take intellectual risks. They begin to see themselves not simply as recipients of knowledge, but as active participants in constructing it.
Perhaps most importantly, choice sends children a powerful message: Your interests matter. Your ideas matter. Your perspective matters. And that sense of agency and belonging is at the very heart of what we hope every child experiences at Lesley Ellis. Warmly, Rhi |
