Colorado 8th Grade Math Standards

All 10 Colorado math standards for 8th grade, each explained in plain English. The official wording is in Colorado Department of Education's document, linked at the end of this page.

10 standards

Number and Quantity

1 standard
MA.8.NS.A
Show that rational numbers have ending or repeating decimals, turn repeating decimals into fractions, and estimate irrational numbers like √2 to compare them and place them on a number line.

Algebra and Functions

5 standards
MA.8.EE.A
Apply exponent rules including negative exponents, solve equations like x² = 49 with square and cube roots, and estimate and compute with very large or small numbers in scientific notation.
MA.8.EE.B
Graph proportional relationships with the unit rate as slope, compare two given in different forms, and use similar triangles to explain why a line has one slope and an equation like y = mx + b.
MA.8.EE.C
Solve one-variable linear equations, including ones with no or infinitely many solutions, and solve systems of two linear equations by graphing or algebra, including in word problems.
MA.8.F.A
Explain a function as a rule giving each input exactly one output, compare functions shown as equations, graphs, tables, or words, and tell linear functions like y = 2x + 1 from nonlinear ones.
MA.8.F.B
Write a linear function from a description or two points, explain its rate of change and starting value, and describe or sketch graphs that show where a relationship rises, falls, or curves.

Data, Statistics, and Probability

1 standard
MA.8.SP.A
Make scatter plots to spot clusters, outliers, and trends, fit a straight line and use its slope and intercept to answer questions, and find patterns in two-way tables of categories.

Geometry

3 standards
MA.8.G.A
Use rotations, reflections, translations, and dilations to move shapes and show they are congruent or similar, and explain angle facts in triangles and around parallel lines.
MA.8.G.B
Explain why the Pythagorean Theorem and its converse work, and use it to find missing side lengths in 2D and 3D problems and distances between points on a grid.
MA.8.G.C
Use the volume formulas for cones, cylinders, and spheres to solve problems, like finding how much a cone-shaped cup or a ball can hold.
