8th Grade Common Core Resources

Here you will find all eighth grade resources to guide and support mathematics teaching and learning.

These resources are organized by mathematical strand and refer to specific Common Core math content standards.

Quick reference: What are these tools?

Geometry

  • 8.G.1

    Verify experimentally the properties of rotations, reflections, and translations.

    Problems of the Month
  • 8.G.2

    Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.

    Problems of the Month
  • 8.G.3

    Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.

  • 8.G.4

    Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.

The Number System (NS)

  • 8.NS.2

    Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., p2).

Expressions and Equations (EE)

Functions (F)

Statistics and Probability (SP)

  • 8.SP.1

    Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.

  • 8.SP.2

    Know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line.
