ABOUT US


WELCOME TO THE LHS MATHEMATICS DEPARTMENT. The math teachers offer courses in Algebra, Geometry, Pre Calculus, Calculus, Statistics, Trigonometry and Computer Programming. There is even a course called Integrated Mathematics.

LHS math teachers use graphing calculators and computers in some courses to help students learn concepts and to make connections. The teachers also prepare students for success on standardized tests (SATs, ACTs, AP exams, MCAS) and assist students in their mastery of the Massachusetts Mathematics Curriculum Frameworks.

Although only two years of math are required for graduation, most students take four years of math at LHS. Got a question, like "When are we ever going to need this in real life?"... Ask a math teacher!

EXPECTATIONS FOR STUDENT LEARNING 

In the area of Number Sense, we believe students should be able to:
    • Judge the reasonableness of numerical computations and their results
    • Use a calculator/computer effectively, efficiently and appropriately
    • Perform elementary operations involving reasonable fractions, decimals and percents without using a calculator
In the area of Algebra, we believe students should be able to:
    • Use symbolic algebra to represent and explain mathematical relationships (i.e., develop and use an algebraic model of mathematical relationships found in daily life)
    • Solve algebraic equations
    • Understand and use formulas for mathematical constructs encountered in daily life
In the area of Geometry, we believe students should be able to:
    • Understand and use formulas for areas and volumes of simple plane figures and three-dimensional solids
    • Develop and use geometric models of mathematical relationships found in daily life
In the area of Measurement, we believe students should be able to:
    • Convert from one measurement system to another
    • Use the English and metric systems appropriately
In the area of Data Analysis and Probability, we believe students should be able to:
    • Understand and use the Fundamental Counting Principle
    • Understand and use various common methods for displaying data
    • Understand and use the measures of central tendency
    • Understand and use basic concepts of probability
We also expect that students will be prepared to:
    • Succeed on standardized tests and external measures of success
    • Apply and adapt a variety of appropriate problem solving strategies
    • Make and investigate mathematical conjectures
    • Use the language of mathematics to express mathematical ideas precisely to peers, teachers and others
    • Successfully apply mathematical ideas, as appropriate, in other contexts
    • Create and use various mathematical representations to organize, understand, and communicate ideas in problem solving
