Sample ATLAS Math Grade 8 Practice Questions

Try these sample questions to review concepts for the ATLAS Math Grade 8 exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which of the following numbers is irrational?
A.√64
B.0.75
C.√11
D.-4/9
Explanation: An irrational number cannot be written as a ratio of integers. √11 is irrational because 11 is not a perfect square.
2Between which two consecutive integers does √45 lie?
A.5 and 6
B.6 and 7
C.7 and 8
D.4 and 5
Explanation: 6² = 36 and 7² = 49. Because 36 < 45 < 49, √45 is between 6 and 7 (about 6.71).
3Which statement correctly compares √30 and 5.5?
A.√30 > 5.5
B.√30 = 5.5
C.√30 < 5.5
D.They cannot be compared without a calculator
Explanation: 5.5² = 30.25. Because 30.25 > 30, 5.5 > √30. Also 5² = 25 and 6² = 36, so √30 is a little more than 5.
4Which list orders the numbers from least to greatest?
A.√2, 1.5, √3, 2
B.1.5, √2, √3, 2
C.√2, √3, 1.5, 2
D.1.5, √3, √2, 2
Explanation: √2 ≈ 1.41, 1.5 = 1.5, √3 ≈ 1.73, and 2 = 2. From least to greatest: √2, 1.5, √3, 2.
5What is √81 + √16?
A.13
B.√97
C.19
D.9
Explanation: √81 = 9 and √16 = 4, so 9 + 4 = 13. You cannot combine them as √(81+16).
6Solve: x³ = 64.
A.x = 4
B.x = 8
C.x = 16
D.x = 32
Explanation: The cube root of 64 is 4 because 4 × 4 × 4 = 64.
7Which number is rational?
A.π
B.√2
C.0.101001000100001… (non-repeating)
D.0.272727… (repeating)
Explanation: A repeating decimal can be written as a ratio of integers. 0.272727… = 27/99 = 3/11, so it is rational.
8√50 is closest to which whole number?
A.6
B.7
C.8
D.9
Explanation: 7² = 49 and 8² = 64. √50 is just above 7 (about 7.07), so it is closest to 7.
9Simplify: 3⁴.
A.12
B.27
C.81
D.243
Explanation: 3⁴ = 3 × 3 × 3 × 3 = 81.
10Simplify: 5⁻².
A.−25
B.−10
C.1/25
D.1/10
Explanation: A negative exponent means reciprocal: 5⁻² = 1/5² = 1/25.

About the ATLAS Math Grade 8 Exam

The Arkansas ATLAS Mathematics — Grade 8 is part of the Arkansas Teaching, Learning, and Assessment System summative program administered by the Division of Elementary and Secondary Education. It measures student achievement of Arkansas Academic Standards in Mathematics for Grade 8. Grade 8 reporting categories include functions in addition to number/algebra and geometry/statistics/probability. The official assessment is computer-adaptive within the grade or course, includes multiple item types (and for ELA a writing component), and is untimed under PATH rules. Results are reported in four performance levels (Level 1–Level 4), with Level 3 or higher indicating grade-level achievement. OpenExamPrep offers free English multiple-choice practice covering topics from ATLAS reporting categories as a study aid—not official items or a full format simulation.

Exam sponsor: Arkansas Division of Elementary and Secondary Education (DESE); delivered by Cambium Assessment, Inc. (CAI) for the Arkansas Department of Education / DESE. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Questions

35 questions

Time Limit

Untimed. The official blueprint lists an estimated average test time of 60 to 70 minutes; PATH sets a 70-minute minimum sit time for Math grades 3–8 (scheduling estimate only — the 2024 Grade 8 average was about 66 minutes).

Passing Score

Results are reported in four performance levels (Level 1–Level 4). Level 3 or higher indicates the student has demonstrated achievement aligned to grade-level Arkansas Academic Standards (2023–24 technical report / 2024 standard setting).

Exam / Certification Fees

Free to students and families; ATLAS is a state-funded statewide summative assessment administered through Arkansas public schools.

ATLAS Math Grade 8: Suggested Study Strategy

1Study the Arkansas Academic Standards and ATLAS reporting categories for Grade 8 Mathematics rather than memorizing random trivia.
2Use the free ATLAS practice/training tests on the official ATLAS portal so students know the online tools before test day.
3Build stamina with untimed practice sessions that mirror one content subject per sitting, matching PATH scheduling guidance.
4Review wrong answers by explaining why each distractor is incorrect using evidence or calculation steps.
5Work multi-step problems and modeling tasks: the official blueprint targets roughly half its items at DOK 2 and about a quarter at DOK 3, so recall alone is not enough.
6Geometry & Measurement/Statistics & Probability is the largest Grade 8 category, so give the Pythagorean Theorem, transformations, volume, and bivariate data proportionate study time.

Frequently Asked Questions

What is the Arkansas ATLAS Mathematics assessment for Grade 8?

It is the statewide end-of-year (or end-of-course) summative assessment in the Arkansas Teaching, Learning, and Assessment System (ATLAS) for Grade 8 Mathematics, administered by DESE and aligned to Arkansas Academic Standards. Results are used for school accountability and to report student achievement.

Who takes this ATLAS assessment?

Arkansas public school students enrolled in the corresponding grade (for grade-level tests) or EOC-eligible course (Algebra I, Geometry, or Biology). Accelerated students may take math EOCs in place of grade-level math when enrolled in the course. Students who qualify for the alternate assessment take DLM instead.

How many questions are on the official ATLAS test?

Official summative blueprint: 35 operational items — Geometry & Measurement/Statistics & Probability 12–14 items (36%), Number Concepts & Computations/Algebra 10–12 items (32%), and Functions 10–12 items (32%) (Arkansas Mathematics Standards Interim and Summative Blueprint, DESE, updated July 28, 2025).

Is ATLAS timed?

No. Official PATH guidance states ATLAS 3–10 content and EOC tests are untimed. Schools schedule minimum sit times for planning, and students should finish a summative content test within one instructional day.

What score is considered proficient?

ATLAS reports four performance levels (Level 1–Level 4). Level 3 or higher indicates achievement aligned to grade-level Arkansas Academic Standards based on the 2024 standard-setting cut scores.

Are these practice questions the real ATLAS exam?

No. These free multiple-choice practice questions are a study aid covering topics from Arkansas standards and ATLAS reporting categories. They are not official ATLAS items and do not replace authentic reading/writing, multi-step math modeling, science investigations, or the official computer-adaptive assessment.
