The Lexington High School Mathematics Department offers a comprehensive four-year mathematics program whose goal is to enable all students to reach high standards and full potential in a supportive, academically focused environment. We seek to engage students in meaningful mathematics that stimulates curiosity and enjoyment, while providing a balance between skill development and conceptual understanding. Throughout our curriculum, we emphasize eight Mathematical Practices identified in the Common Core State Standards and the Massachusetts Curriculum Framework for Mathematics.

Students will need a Texas Instruments TI-84 or TI-83 calculator for all math courses at LHS. Our school recommends purchasing such a calculator which can be used for all 4 years of high school. Access for everyone is our priority, so we also make long-term loans of calculators to any student who needs one. Students can borrow a calculator by seeing Ms. Butterfly in office 711, any school day 8:00-11:30 a.m. Students must return the calculator when they no longer need it, or before leaving or graduating LHS, or else there's a charge for the calculator's value.

Our department has a longstanding practice of releasing final exams for most courses on a two-year cycle. We hope that our released exams will be useful to students preparing for final exams. You can find our released final exams in this folder. Note however that we did not give any final exams in 2020 or 2021.
