New Hampshire Algebra I: Key Topics and Standards
Algebra I is a foundational high school math course in New Hampshire. It introduces students to the abstract reasoning and problem-solving skills they will use in every math course that follows. All topics on StudyPug align to the New Hampshire Mathematics Model Competencies, the same standards used in NH classrooms.
Equations and Inequalities
Students learn to create and solve equations and inequalities in one variable, including those arising from linear, quadratic, rational, and exponential functions. They also learn to rearrange formulas to isolate a quantity of interest — a skill used throughout science and engineering courses.
- Solve linear equations and inequalities in one variable
- Create equations in two or more variables and graph them on coordinate axes
- Represent constraints using systems of equations and inequalities
- Justify each step in solving an equation using properties of equality
Systems of Equations
Students solve systems of two linear equations exactly and approximately, including graphical methods. They learn why replacing one equation with a linear combination produces an equivalent system — a key concept for later coursework in linear algebra.
Functions
A major focus of Algebra I is understanding what a function is and how to work with function notation. Students interpret key features of graphs and tables, calculate average rates of change, and compare functions represented in different forms.
- Understand domain and range
- Use function notation and evaluate functions
- Graph linear, quadratic, absolute value, and exponential functions
- Identify transformations: f(x) + k, k·f(x), f(kx), and f(x + k)
Linear and Exponential Models
Students distinguish between situations modeled by linear functions and those modeled by exponential functions. They construct both types from graphs, tables, and verbal descriptions, and interpret parameters such as slope, intercept, and growth rate in real-world contexts.
Polynomials and Rational Exponents
Students add, subtract, and multiply polynomials, and factor them to identify zeros. They also extend their understanding of integer exponents to rational exponents, connecting radical notation to exponential form.
Quadratic Equations
Students solve quadratic equations in one variable using factoring, completing the square, and the quadratic formula. They also solve systems consisting of one linear and one quadratic equation both algebraically and graphically.
Statistics and Data Analysis
Algebra I introduces statistical reasoning. Students represent data using dot plots, histograms, and box plots. They compare data sets using measures of center and spread, and analyze scatter plots to describe relationships between two quantitative variables.
- Compare mean, median, interquartile range, and standard deviation
- Interpret slope and intercept of a linear model in context
- Compute and interpret the correlation coefficient using technology
- Distinguish between correlation and causation
