ID | Standard | StudyPug Topic |
|---|---|---|
8.NS.A.1 | Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number. |
8.NS.A.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., π2). |
8.EE.A.1 | Know and apply the properties of integer exponents to generate equivalent numerical expressions. |
8.EE.A.2 | Use square root and cube root symbols to represent solutions to equations of the form x2 = p and x3 = p, where p is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational. |
8.EE.A.3 | Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. |
8.EE.B.5 | Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. |
8.EE.B.6 | Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b. |
8.EE.C.7 | Solve linear equations in one variable. |
8.EE.C.8 | Analyze and solve pairs of simultaneous linear equations. |
8.F.A.1 | Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output. |
8.F.A.2 | Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). |
8.F.B.4 | Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values. |
8.F.B.5 | Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally. |
8.G.A.1 | Verify experimentally the properties of rotations, reflections, and translations. |
8.G.A.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. |
8.G.A.3 | Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates. |
8.G.A.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. |
8.G.A.5 | Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles. |
8.G.B.6 | Explain a proof of the Pythagorean Theorem and its converse. |
8.G.B.7 | Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions. |
8.G.B.8 | Apply the Pythagorean Theorem to find the distance between two points in a coordinate system. |
8.G.C.9 | Know the formulas for the volumes of cones, cylinders, and spheres and use them to solve real-world and mathematical problems. |
8.SP.A.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.A.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. |
Ohio 8th Grade Math: Key Topics
Ohio's Learning Standards for 8th grade math are designed to build a strong foundation for high school algebra and geometry. Students tackle a wide range of topics this year, from number systems and expressions to geometry and statistics.
- Number Systems: Students learn to distinguish rational from irrational numbers, use decimal expansions, apply integer exponent properties, and work with square and cube roots.
- Scientific Notation: Students express very large and very small numbers using powers of 10 and perform operations with numbers in scientific notation.
- Expressions and Equations: Topics include slope, proportional relationships, linear equations in one variable, and systems of simultaneous linear equations.
- Functions: Students define functions, compare representations, interpret linear functions, model linear relationships, and analyze graphs qualitatively.
- Geometry: Rotations, reflections, translations, dilations, congruence, similarity, angle relationships, the Pythagorean Theorem, and volume of cones, cylinders, and spheres.
- Statistics and Probability: Scatter plots, linear models for bivariate data, slope and intercept interpretation, and two-way tables for categorical data.
How StudyPug Supports Ohio 8th Grade Math Students
StudyPug provides video lessons and practice problems aligned to Ohio's Learning Standards Math. Every lesson is broken into short segments students can watch, pause, and replay. After each lesson, students can test their understanding with practice problems that include step-by-step solutions.
Whether a student needs to review irrational numbers before a quiz or wants to get ahead on the Pythagorean Theorem, StudyPug makes it easy to find the right topic and start learning immediately.
Preparing for the Ohio State Tests
Ohio administers the Ohio State Tests for math in 8th grade. StudyPug's content covers every topic assessed, so students can use it throughout the year to build confidence and be ready for test day. Practice problems mirror the types of questions students will see on the Ohio State Tests, helping them apply what they've learned.
