United States 7th/8th Grade Curriculum - Mathematics (Pre-Algebra, Algebra I)

This curriculum outlines the key mathematical concepts typically covered in 7th and 8th grades in the United States, encompassing pre-algebra and Algebra I.

Pre-Algebra (7th Grade)

Pre-algebra in 7th grade builds a foundation for higher-level math. Key topics include:

  • Numbers and Operations:
      • Integers: Adding, subtracting, multiplying, and dividing integers.
      • Decimals and Fractions: Operations with decimals and fractions, converting between the two.
      • Rational Numbers: Understanding and comparing rational numbers.
      • Absolute Value: Understanding the concept of absolute value.
  • Algebraic Concepts:
      • Variables and Expressions: Evaluating and simplifying algebraic expressions.
      • Solving Equations and Inequalities: Solving one-step equations and inequalities.
  • Ratios, Proportions, and Percentages:
      • Ratios and Rates: Understanding and applying ratios and rates.
      • Percentages: Calculating percentages and solving percentage problems.
  • Geometry:
      • Basic geometric shapes and their properties.
  • Probability and Statistics:
      • Introduction to probability and basic statistical concepts.

Algebra I (8th Grade)

Algebra I in 8th grade introduces more complex algebraic concepts, building upon the foundation laid in pre-algebra. Key topics include:

  • Solving Equations and Inequalities:
      • Solving multi-step equations and inequalities with variables on both sides.
      • Solving systems of equations.
  • Linear Equations and Functions:
      • Understanding linear equations and their graphs.
      • Working with linear functions and their properties.
  • Exponents and Exponential Functions:
      • Introduction to exponents and exponential functions.
  • Polynomials and Factoring:
      • Operations with polynomials.
      • Factoring polynomials.
  • Radicals and Quadratic Equations:
      • Introduction to radicals and basic quadratic equations. (Often introduced in later stages of Algebra I)

This curriculum provides a comprehensive overview of the math skills and concepts typically taught in 7th and 8th grades, preparing students for higher-level math courses in high school. Resources like Khan Academy, Cuemath, and others offer additional practice and support for these topics.
