High School / Secondary Math Teacher

Quantitative Reasoning - Middle & High School

Dates: August 24 - November 28, 2026 (14 weeks)

Location: Jelsa, Croatia

About The Field School of Hvar

The Field School of Hvar is a full-time enrichment program located in a seaside village in Croatia. We bring together children ages 3 through 15 from around the world for deep engagement with ideas, culture, and the natural world. Small groups, meaningful work, and genuine community are at the heart of everything we do.

About the Role

The Upper School Math Guide will lead tutorials in quantitative reasoning for our two oldest groups: 12 children ages 11–12 (middle school) and 14 children ages 13–15 (secondary). You will meet with each group four times per week for 80 minutes per session. Sessions will generally take place outside, weather and other practicalities permitting.

Our quantitative reasoning program is rooted in a conviction that children fall in love with mathematics when they “discover” it. Our curriculum leads learners to the kitchen, to entrepreneurship, and through some of the most powerful examples of mathematical thought in Western history. Across both groups, you will move between applied, hands-on quantitative reasoning and the close study of foundational ideas.

Mathematics Program

Middle School (ages 11–12)

The middle school math program centers on the Field Store project: a student-run social enterprise producing and selling small-batch pantry goods rooted in Dalmatian craft traditions. Mathematics arises naturally from the work of the enterprise throughout the year. More about the Field Store project here: fieldschoolhvar.org/field-store.

Sessions rotate among:

• Recipe math — scaling recipes up and down, unit conversion, ratio and proportion in the context of fermentation, pickling, and preservation
• Market and budget math — pricing, profit margins, multi-step transactions, and working with real budgets as the enterprise develops
• Estimation and data collection — graphing over time, basic statistics, and quantitative reasoning drawn from observations of the garden and natural world

Secondary School (ages 13–15)

The secondary math program moves between applied quantitative work grounded in the Field Store and the close study of primary mathematical texts — treating mathematics as a humanistic discipline with a history and a logic worth understanding on its own terms.

• First six weeks: Nature-based quantitative reasoning using algebra — estimating soil volumes, compost needs, and garden yields; Field Store budgeting and market exercises; estimation and data collection
• Final six weeks: Euclid’s Elements, Book I — working from a custom teaching edition adapted from the Green Lion annotated study edition, with discussion questions and guided practice designed for early high school learners. The goal is genuine engagement with mathematical proof, not rote geometry.

Schedule and Responsibilities

Teaching Days

The school day runs 9:00am–4:00pm. Upper School Math tutorials take place in the afternoon, preceded by a faculty hour from 12:00–1:00pm. During the faculty hour, teachers manage assessment documentation, communicate with the administrative team, and prepare materials for the following day.

On Fridays, you will help students prepare and present a brief summary of the week’s work for parents. This is a valued part of how we keep families connected to their children’s learning.

Non-Teaching Day

One day each week (equivalent to one day in five) is reserved for non-teaching work, divided among three activities:

• Planning and administration — curriculum preparation, collaboration with other guides and specialist fellows, and coordination with the administrative team
• Workshop for local children — a free or low-cost offering for children from the Jelsa community who are enrolled in Croatian public school and cannot participate in the full program
• Workshop for community adults — open to Field School parents and local adults, connecting the school’s activities to a wider audience

Assessment and Documentation

There is no formal grading. Instead, you will be expected to:

• Conduct entry and exit skill assessments for internal planning (e.g. assigning groups)
• Maintain ongoing observational notes on each student’s development
• Issue a brief weekly summary of work covered with each group
• Contribute to ongoing program assessment — what’s working, what needs adjustment

The administrative team manages parent communication, disciplinary matters, and family concerns. Teachers are not expected to interface with parents beyond the Friday presentations, community workshops, and everyday pleasantries. Our communication policies are described in detail in the staff handbook.

About You

We are looking for someone who brings several of the following:

• A strong foundation in mathematics and enthusiasm for teaching it
• Eagerness to teach math through applied, real-world contexts and interdisciplinary techniques
• Excitement to introduce Euclid to teens
• Experience working with middle and high school-age students
• Warmth and adaptability within a small, close-knit school community

Backgrounds in classroom teaching, tutoring, museum education, educational media, and other experiential learning settings are warmly welcome.

Other Details

• Fluency in English is required. Croatian is not required but warmly welcomed.
• This position may be combined with another full-time role (like the upper school math teaching position) for a full-time position / salary. We are also open to hiring permanent faculty, if that is of interest.
• For more information about our program, visit www.fieldschoolhvar.org

All benefits and protections in accordance with Croatian law.

Full scholarship to up to two children included.

English fluency required
