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.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.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.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.

Everything your child needs to know about Grade 8 Math with StudyPug

Is StudyPug aligned with the Massachusetts Grade 8 curriculum?

Yes! StudyPug is 100% aligned with Massachusetts Curriculum Frameworks for Grade 8 Mathematics. Every lesson covers the specific standards your child is learning in school—from rational and irrational numbers to linear equations, functions, transformations, the Pythagorean theorem, and data analysis.

What topics are covered in Grade 8 Math?

Grade 8 Math covers number systems (rational vs. irrational numbers), exponents and scientific notation, linear equations and systems of equations, functions and graphing, transformations and symmetry, similar figures, the Pythagorean theorem and its applications, volume and surface area of 3D shapes, and scatter plots and data analysis.

How does StudyPug help my Grade 8 child learn math?

Your child watches short video lessons taught by certified Massachusetts teachers, practices with problems that match what they're learning in class, and gets step-by-step solutions for every question. They can also snap a photo of any homework problem and find the exact lesson they need. Progress tracking shows you exactly where they're improving and where they need more help.

Can my child use StudyPug independently?

Absolutely! StudyPug is designed for independent learning. Your Grade 8 child can browse topics, search for specific problems, watch videos at their own pace, and practice until they master each concept. You can check progress reports anytime to see how they're doing without interrupting their work.

Does StudyPug prepare students for the MCAS?

Yes! StudyPug includes practice problems that mirror MCAS Mathematics question formats and difficulty levels. Your child will practice the same types of problems they'll see on test day, building both skills and confidence. Many Massachusetts families use StudyPug specifically to prepare for MCAS.
