Sample SC READY Math Grade 8 Practice Questions

Try these sample questions to test your SC READY Math Grade 8 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Simplify the expression 5³ × 5⁴ using the properties of integer exponents.
A.5⁷
B.5¹²
C.25⁷
D.
Explanation: When multiplying expressions with the same base, add the exponents: 5³ × 5⁴ = 5³⁺⁴ = 5⁷ = 78,125.
2Simplify the expression (4³)².
A.4⁵
B.4⁶
C.
D.12²
Explanation: When raising a power to a power, multiply the exponents: (4³)² = 4³ˣ² = 4⁶ = 4,096.
3Simplify the expression 7⁸ / 7⁵.
A.7¹³
B.7⁴
C.
D.
Explanation: When dividing expressions with the same base, subtract the exponent of the denominator from the exponent of the numerator: 7⁸ / 7⁵ = 7⁸⁻⁵ = 7³ = 343.
4Evaluate 3⁻⁴.
A.-12
B.-81
C.1/81
D.1/12
Explanation: A negative exponent represents the reciprocal of the base raised to the positive exponent: 3⁻⁴ = 1 / 3⁴ = 1 / 81.
5Evaluate the expression (15.8)⁰ + 2³.
A.9
B.1
C.8
D.18.8
Explanation: Any non-zero real number raised to the power of 0 equals 1, so (15.8)⁰ = 1. Since 2³ = 8, the sum is 1 + 8 = 9.
6Which of the following numbers is irrational?
A.√49
B.0.333...
C.√12
D.-5/8
Explanation: √12 cannot be expressed as a fraction of two integers because 12 is not a perfect square (√12 = 2√3 ≈ 3.4641...). Therefore, √12 is an irrational number.
7Evaluate √144 - √25.
A.7
B.119
C.17
D.9
Explanation: Since √144 = 12 and √25 = 5, the expression simplifies to 12 - 5 = 7.
8Evaluate ∛64 + ∛125.
A.9
B.63
C.7
D.14
Explanation: The cube root of 64 is 4 (since 4³ = 64) and the cube root of 125 is 5 (since 5³ = 125). Adding them gives 4 + 5 = 9.
9Between which two consecutive integers does √50 lie on a number line?
A.5 and 6
B.6 and 7
C.7 and 8
D.8 and 9
Explanation: Identify the perfect squares closest to 50: 49 < 50 < 64. Taking square roots gives √49 < √50 < √64, which means 7 < √50 < 8. (√50 ≈ 7.07).
10Express 680,000,000 in scientific notation.
A.68 × 10⁷
B.6.8 × 10⁸
C.6.8 × 10⁷
D.0.68 × 10⁹
Explanation: In scientific notation, a number is written as a × 10ⁿ where 1 ≤ a < 10. Moving the decimal point 8 places to the left gives 6.8 × 10⁸.

About the SC READY Math Grade 8 Exam

The SC READY Grade 8 Mathematics assessment measures student mastery of the South Carolina College- and Career-Readiness Standards for Mathematics. It covers irrational numbers, scientific notation, linear equations and systems, functional relationships, the Pythagorean Theorem, transformations, volume, and bivariate data statistics.

Assessment

Fifty operational items assessing the 2025 South Carolina College- and Career-Ready Mathematics Standards: Data, Probability, and Statistical Reasoning 8-10 items; Measurement, Geometry, and Spatial Reasoning 15-19; Numerical Reasoning 7-9; Patterns, Algebra, and Functional Reasoning 14-18. Depth of Knowledge ranges are DOK 1 at 15-40%, DOK 2 at 55-85%, and DOK 3 at 0-10%.

Time Limit

Not timed. SCDE publishes an approximate 100 minutes for grades 6-8 mathematics for scheduling only. The test is given in a single day in two sections; in Spring 2026 the No Calculator section is presented first, followed by the Calculator section.

Passing Score

No pass mark is set. SC READY results are reported in four performance levels: Does Not Meet Expectations, Approaches Expectations, Meets Expectations, and Exceeds Expectations.

Exam Fee

No fee to students (South Carolina Department of Education (SCDE); online delivery on DRC INSIGHT (Data Recognition Corporation))

SC READY Math Grade 8 Study Tips from Top Performers

1Master exponent rules (product, quotient, power of a power, zero, and negative exponent rules) and scientific notation arithmetic.
2Practice finding slope using m = (y2 - y1) / (x2 - x1) and converting linear equations to slope-intercept form (y = mx + b).
3Understand the difference between linear functions (constant rate of change) and non-linear functions (varying rate of change).
4Memorize key geometric formulas: Pythagorean Theorem (a^2 + b^2 = c^2), Volume of Cylinder (V = π r^2 h), Cone (V = 1/3 π r^2 h), and Sphere (V = 4/3 π r^3).
5Interpret scatter plot trends (positive, negative, nonlinear, or no association) and practice reading relative frequency from two-way tables.
