8th grade math test: a free 10-question quick check
This free math test for 8th graders has ten questions on the year’s main topics. It takes about 10 to 15 minutes. It is a quick check, not a full assessment.
In this quick check, every child gets the same ten questions, which represent a selection of the most relevant ones for 8th grade. Unlike the full Level Up assessment, this check does not adapt to a child’s answers. The result shows which questions your child missed, but it cannot identify foundational knowledge gaps. For the full picture, the Level Up assessment adapts to each answer and finds the earliest skill that is missing. It is included in the free trial.
10 questions, about 10 to 15 minutes. Skipping is fine. Nothing is saved.

What the questions cover
The ten questions sample 8th grade: exponents and square roots, irrational numbers, functions, transformations on a grid and scatter plots. Some questions show a graph or a grid; one asks your child to type an answer.
The whole year covers these areas:
Linear equations and slope
The center of 8th grade. Your child connects a graph, a table and an equation for the same straight line, and solves equations with the unknown on both sides.
Functions
A function is a rule that gives exactly one output for each input. This is the first year children study functions by name, and Algebra 1 is built on them.
Exponents, roots and scientific notation
The rules for powers, including zero and negative exponents, plus square roots, cube roots and very large or very small numbers written in scientific notation.
Transformations, congruence and angles
Shapes slide, flip, turn and resize on a coordinate grid. These moves explain what it means for two shapes to be congruent or similar, and they lead to angle facts about triangles and parallel lines.
The Pythagorean theorem
In a right triangle, a² + b² = c². Your child learns why it is true, uses it to find missing sides and uses it to find the distance between two points on a grid.
Irrational numbers
Some numbers, like √2 and π, cannot be written as a fraction. Your child learns to tell rational from irrational numbers and to estimate where an irrational number sits on a number line.
Scatter plots and data
Data with two measurements per person or object: scatter plots, a line of best fit and two-way tables.
Volume of cylinders, cones and spheres
Three volume formulas, used on real objects such as cans, ice cream cones and balls.
Every topic of the year, explained for parents, is on the 8th grade math page.
What you see at the end
The score, then every question with your child’s answer, the correct answer and a worked solution. A short message explains what a similar score usually means for 8th graders on our full assessment. Treat it as an indication: ten fixed questions cannot measure where a child stands.
Common questions
What math should an 8th grader know?
By the end of 8th grade: solving linear equations, including systems of two equations; slope and y = mx + b; what a function is; the exponent rules and scientific notation; transformations on a grid; and the Pythagorean theorem. The 8th grade math page explains each topic for parents.
Is this 8th grade math test the same for every child?
Yes. Every child gets the same ten questions, and the test does not change as your child answers. That makes it quick, but it can only show which questions were missed, not why.
Can I print the 8th grade math test?
Yes. The same ten questions come as a PDF, with a separate answer key that has the worked solutions.
What if my child gets most of it right?
That is a good sign for this year’s main topics. Ten questions cannot cover the whole year, so a strong score is a reason to check the rest, not to skip it.
