About The Position

Lake Chelan High School is seeking a knowledgeable, collaborative, and student-centered mathematics teacher for a non-continuing position serving the remainder of the 2026–27 school year. The position is 1.0 FTE, with a start date of February 1, 2027, and a contract lasting from the agreed-upon start date through the remainder of the school year. The teacher will plan and deliver standards-aligned instruction using the district-adopted curriculum and established course sequences, teaching across Algebra I, Geometry, and Algebra II. The role calls for understanding how mathematical concepts and prerequisite skills connect across these courses, and balancing conceptual understanding, procedural fluency, reasoning, and application. The teacher will support students through formative assessment, feedback, differentiated instruction, targeted reteaching, and accommodations, while fostering a welcoming classroom with high expectations and a sense of belonging. The role also involves collaboration with colleagues and support staff, communication with families, maintaining student records, and helping students connect mathematics to future education, careers, and everyday decision-making.
