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:
Make sense of problems and persevere in solving them.
Reason abstractly and quantitatively.
Construct viable arguments and critique the reasoning of others.
Model with mathematics.
Use appropriate tools strategically.
Attend to precision.
Look for and make use of structure.
Look for and express regularity in repeated reasoning.

2024-25 curriculum information
Information about next year's courses appears in the Math Department section of the LHS Program of Studies 2024-2025.
For LHS Curriculum Night on February 1, we have program overviews for Math and Computer Science, and from 7 to 8 p.m. we'll have Math and Computer Science tables staffed with faculty ready to answer your questions.
Placement Review Forms (for appeals and for skipping courses) are available on this page.
More information about specific offerings:
We offer several computer science courses. You can learn more about them from these slides and course descriptions.
If you're interested in Python computer programming but not sure whether to choose Introductory Python or Intermediate Python, this diagnostic test will help you decide.
Curious about 12th grade course Contemporary Applied Math? Here are some slides about Contemporary Applied Math.
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.
Math 1 solutions: https://goo.gl/taSWob
Math 2 solutions: https://goo.gl/9eda89
Math 3 solutions: https://goo.gl/tej4Vt
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.
Other information
On the 2023 Grade 10 Math MCAS, LHS had 49% of its students exceeding expectations, 94% meeting or exceeding expectations, and less than 1% needing to retake the test to be able to graduate. (For comparison, statewide, these numbers are 10%, 50%, 9%.) More details are available from Massachusetts DESE.
