Lake Country School is a Montessori learning environment that fosters independence, critical thinking, and creativity within each child. We are a community that promotes diversity and inclusion, as well as respect and responsibility to self, to others, and to the earth.

Lake Country School (LCS) is a vibrant Montessori community serving students from Children's House through Junior High, including a unique Land School program. We are committed to Montessori pedagogy, strong faculty culture, meaningful family partnerships, and a deep commitment to Equity, Diversity, and Justice. Our urban and rural campuses offer a rich and distinctive educational environment, and our community is passionate, engaged, and mission-driven.

Lake Country School seeks an Adolescent Math Guide to teach mathematics, specifically a foundation in Algebra, to 7th and 8th grade students in our Junior High program. This position is highly collaborative. The Math Guide co-teaches with the Science Guide in our integrated Field Studies program, taking the lead directing Math lessons and supporting Science lessons. The Math guide also works closely within the JH core team composed of the Field Studies and Humanities teachers (English and Social Studies), as well as with specialist teachers and Land School staff to connect learning across subjects.

The Math Guide creates an engaging classroom where students build mathematical understanding and skills through inquiry, problem solving, discussion, and real‑world applications that reflect diverse perspectives and reference their own experience. The guide helps students develop confidence, independence, and perseverance while providing instruction and support that meets the developmental needs of adolescents.

Beyond the classroom, the Math Guide is an active member of the Junior High team, participating in field experiences, camping trips, travel, and student mentorship. The guide also shares responsibility for planning school programs, participating as a member of the staff community in development, planning and outreach work, and helping maintain a safe, welcoming, and well‑prepared learning environment.

• Teach math at the 7th and 8th grade levels, continuing to develop a hands‑on Montessori algebra curriculum that builds on concepts, practices and materials from Children's House, Elementary 1, and Elementary 2, including some utilization of the IXL program.

• Deliver a curriculum of foundational algebra over the two years of Junior High, designed so students can access it in either order (typically a linear year and an exponential year).

• Implement student-centered, inquiry-based learning grounded in the developmental needs and tendencies of the adolescent, along with curriculum writing and systematic best practices in math teaching from a diverse perspective.

• Use practical applications and projects to make math concepts accessible and spark genuine interest.

• Establish clear objectives for lessons, units, and projects using formal and informal assessment data.

• Use a variety of culturally relevant practices to support content standards and the needs and capabilities of individual students and groups.

• Create a classroom environment conducive to learning and appropriate to the maturity and interests of the students.

• Co‑teach with the Junior High Science Guide, applying math curriculum to concurrent science curriculum. For example: exponential growth and cell reproduction; ratios of surface area to volume and forms in nature; multiplication of exponents and frequency relationships in the musical scale (the "circle of fifths"); calculating mechanical advantage; and many more.

• Collaborate with the Science guide to utilize their experience to support in the classroom and to create and schedule lessons, co‑ordinate support for students across both disciplines, and support Science lessons when needed.

• Collaborate as part of a team of…
