Grade 8 · Common Core review
Grade 8 algebra readiness: Common Core review
Grade 8 is where arithmetic turns into algebra: exponents, linear equations, slope, and functions. This page groups the CCSS Grade 8 math standards into teachable clusters, each linked to a plain-English standard page, with foundational worksheet practice where it exists.
The number system: rational & irrational numbers
Understand that every number is rational or irrational, and convert repeating decimals to fractions.
Exponents & scientific notation
Apply the properties of integer exponents and estimate very large or very small quantities.
Solving linear equations
Solve linear equations in one variable, including equations with variables on both sides, and systems of equations.
Proportional relationships, slope & functions
Graph proportional relationships, understand slope, and construct and compare linear functions.
Transformations, angles & the Pythagorean theorem
Reason about rotations, reflections and dilations, angle relationships, and apply the Pythagorean theorem.
Scatter plots & lines of best fit
Build and interpret scatter plots for bivariate data and fit a line to a linear association.
