1Which of the following numbers is irrational?

A.0.5

B.√16

C.π

D.-3/4

Explanation: An irrational number cannot be written as a ratio of two integers. 0.5 = 1/2, √16 = 4, and -3/4 are all rational. π cannot be expressed as a ratio of integers and has a non-terminating, non-repeating decimal expansion, so it is irrational.

2Which number is rational?

A.√7

B.0.1010010001... (non-repeating, non-terminating)

C.√11

D.3.8

Explanation: 3.8 = 38/10 = 19/5, a ratio of two integers, so it is rational. √7 and √11 have non-terminating, non-repeating decimals, and the pattern 0.1010010001... never repeats, so all three are irrational.

3Between which two consecutive integers does √23 lie?

A.3 and 4

B.4 and 5

C.5 and 6

D.6 and 7

Explanation: Since √16 = 4 and √25 = 5, and 16 < 23 < 25, we have 4 < √23 < 5. So √23 lies between 4 and 5.

4What is √81?

A.8

B.9

C.40.5

D.81

Explanation: √81 is the positive number that squares to 81. Since 9 × 9 = 81, √81 = 9.

5What is ∛64?

A.4

B.8

C.16

D.21.3

Explanation: ∛64 is the number that cubes to 64. Since 4 × 4 × 4 = 64, ∛64 = 4.

6What is the decimal 0.3̄ (0.333...) as a fraction in simplest form?

A.3/10

B.1/3

C.3/100

D.33/100

Explanation: Let x = 0.333... Then 10x = 3.333..., so 10x - x = 3, giving 9x = 3 and x = 3/9 = 1/3.

7Express 5 × 10^4 in standard form.

A.504

B.5,000

C.50,000

D.500,000

Explanation: 5 × 10^4 = 5 × 10,000 = 50,000. Multiplying by 10 four times shifts the decimal four places to the right.

8What is 2^5?

A.10

B.25

C.32

D.16

Explanation: 2^5 = 2 × 2 × 2 × 2 × 2 = 32. The exponent 5 tells how many times to use 2 as a factor.

9Estimate √40 to the nearest tenth.

A.5.6

B.6.3

C.7.1

D.20

Explanation: √36 = 6 and √49 = 7, so √40 is slightly above 6. Since 6.3^2 = 39.69 ≈ 40, √40 ≈ 6.3 to the nearest tenth.

10Which is larger: √2 or ∛3?

A.√2

B.∛3

C.They are equal

D.Cannot be compared

Explanation: √2 ≈ 1.4142 and ∛3 ≈ 1.4422. Comparing the decimal approximations, 1.4422 > 1.4142, so ∛3 is larger than √2.

About the Nebraska NSCAS Math Grade 8 Exam

The Nebraska Student-Centered Assessment System (NSCAS) Mathematics assessment at Grade 8 measures proficiency on the Nebraska College and Career Ready Standards (NCCRS) for Mathematics across four reporting categories: Number, Algebra, Geometry, and Data. It is an item-adaptive (multi-stage) online assessment delivered by NWEA in spring, with new mathematics cut scores established in 2024. This 100-question practice bank uses four-option MCQs as an English-language study adaptation.

Nebraska NSCAS Math Grade 8 Study Tips from Top Performers

1To estimate an irrational square root like √23, bracket it between two perfect squares (16 < 23 < 25) so 4 < √23 < 5.

2For scientific notation multiplication, multiply the coefficients and add the exponents; for division, divide the coefficients and subtract the exponents.

3Solve a linear equation by isolating the variable: distribute, combine like terms, then use inverse operations on both sides.

4Apply the Pythagorean Theorem a^2 + b^2 = c^2 only to right triangles, with c as the hypotenuse; the distance formula is the same idea in the coordinate plane.

5Match each volume formula to its solid: cylinder (pi)r^2 h, cone (1/3)(pi)r^2 h, sphere (4/3)(pi)r^3.
