Lexington High School Math Department

About the LHS mathematics program

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 these eight Mathematical Practices identified in the Common Core State Standards and the Massachusetts Curriculum Framework for Mathematics:

Mathematics and Black History

Lexington High School's Math Department stands together with our school community and the Lexington and Boston communities in our commitment to diversity, equity, inclusion, and anti-racist practices to break cycles of racism and oppression. 

We also reaffirm the value of diverse contributors to our field of knowledge. Exemplifying that diversity, here's the math exhibit from LHS's Black History Month online museum, assembled by LHS teachers and students:

Calculators for math classes

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. A student can borrow a calculator by seeing Ms. Butterfly in office 711, weekdays 7:45-11:30 a.m. anytime during the school year. (There is no longer a Google Form to complete as in the past.)

Textbook solution files

Students in Math 1, Math 2, and Math 3 courses have access to online solution files for the CME Project textbooks that are partially used in those courses. To access any of these, you first need to be logged into your lexingtonma.org google account, then use these links.

Unfortunately LHS no longer has a license to give students online access to digital versions of these textbooks, but students will receive a paper copy of the textbook, and we will have some additional copies available at school.

Final exam archive

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.
