Ohio's State Test Grade 8 Math sample questions with answers
Questions in the test's style, each with the answer and an explanation. Open the answer once your child has tried the question.
Question 1 · Grade 8 Math · Standard 8.EE.7
Solve: -2(3x - 5) = 4
- A.x = -1
- B.x = 1
- C.x = 2
- D.x = 3
Show the answer and explanation
Answer: B. x = 1
-6x + 10 = 4. Subtract 10: -6x = -6. Divide: x = 1.
Question 2 · Grade 8 Math · Standard 8.G.9
A sphere has radius 6 cm. What is the volume? (Use π ≈ 3.14)
- A.113.0 cm³
- B.452.2 cm³
- C.678.2 cm³
- D.904.3 cm³
Show the answer and explanation
Answer: D. 904.3 cm³
V = (4/3)πr³ = (4/3)(3.14)(216) = (4/3)(678.24) = 904.32 ≈ 904.3 cm³.
Question 3 · Grade 8 Math · Standard 8.F.1
Which of these represents a function?
- A.(1,2), (1,3), (2,4)
- B.(1,2), (2,3), (3,4)
- C.(5,1), (5,2), (5,3)
- D.(0,0), (0,1), (1,1)
Show the answer and explanation
Answer: B. (1,2), (2,3), (3,4)
A function assigns each input exactly one output. Only option B has no repeated x-value with different y-values.
About the Ohio's State Test Grade 8 Math Test
Grade 8 is the mathematical bridge to high school in Ohio: the content is built around functions and linear relationships, the foundation of Algebra I. In spring 2026, 52% of Ohio eighth graders were proficient, up from 48% in spring 2025.
ODEW reports grade 8 math in five strands: Functions, Expressions & Equations, Geometry, The Number System, and Modeling & Reasoning. The signature skills are understanding functions, graphing and interpreting linear relationships (slope and intercept), the Pythagorean theorem, and exponents and scientific notation.
Ohio's State Tests are fixed-form tests given online through Cambium's Ohio portal, with paper as an accommodation (ODEW). Grade 8 math has two sections of up to 90 minutes each, and ODEW allows a calculator on all grade 8 items.
Proficient + Accomplished + Advanced (scale 700+). Basic (Level 2) and Limited (Level 1) are below Proficient. Up from 48% in spring 2025.
