Grade 8 Math

Eighth graders engage in a rigorous Algebra I curriculum. This is accomplished by ensuring facility with graphing, graph interpretation, algebraic expressions, functions, and other representations leading to an increase in flexibility and the development of multiple forms of reasoning. A variety of techniques such as direct instruction, collaborative learning, and project work are used, placing the focus on both the process and the product. Students are generally prepared for Geometry or Algebra II in ninth grade.

Topics of study include:

  • Relationships
  • Linear equations
  • Linear systems
  • Linear inequalities
  • Polynomials
  • Quadratic functions
  • Radical functions
  • Rational functions

Eighth grade students will:

  • think clearly, use logical reasoning, and communicate effectively about their understandings and solutions
  • identify relationships, sketch, and interpret graphs
  • write, evaluate, and solve equations 
  • graph linear equations and understand slope as a rate of change
  • solve systems of equations
  • compute and reason with real numbers
  • solve and graph inequalities
  • explore exponential functions
  • write and solve polynomial equations
  • solve and graph quadratic equations
  • simplify, solve, and graph radical equations
  • simplify rational expressions
  • work neatly, check work, attend to precision, select efficient approaches, and have a repertoire of strategies
  • use data as a context for algebraic thinking
  • develop facility with proportional reasoning and other real world applications of algebraic concepts
