Sample Missouri MAP Grade 8 Math Practice Questions

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

1The square root of 50, √50, lies between which two consecutive integers?

A.5 and 6

B.7 and 8

C.6 and 7

D.8 and 9

Explanation: Since 7² = 49 and 8² = 64, and 50 is between 49 and 64, √50 lies between 7 and 8 (approximately 7.07).

2Which of the following numbers is irrational?

A.√16

B.0.333...

C.22/7

D.π

Explanation: π (pi) is an irrational number because its decimal representation is non-repeating and non-terminating. √16 = 4 (integer), 0.333... = 1/3 (rational), and 22/7 is a ratio of two integers (rational).

3What is the value of ∛64 (the cube root of 64)?

A.8

B.16

C.21.3

D.4

Explanation: The cube root of 64 is 4 because 4 × 4 × 4 = 64.

4Solve the equation x² = 81 for x.

A.x = 40.5

B.x = 9 only

C.x = ±81

D.x = ±9

Explanation: Taking the square root of both sides gives x = ±√81 = ±9, because both (9)² = 81 and (-9)² = 81.

5What is the repeating decimal 0.444... expressed as a simplified fraction?

A.4/9

B.4/10

C.2/5

D.4/100

Explanation: Let x = 0.444... Then 10x = 4.444... Subtracting the two equations gives 9x = 4, so x = 4/9.

6Simplify: 4³ × 4⁵

A.4⁸

B.4¹⁵

C.16⁸

D.16¹⁵

Explanation: When multiplying exponential expressions with the same base, add the exponents: 4³⁺⁵ = 4⁸.

7Simplify: 7⁹ / 7³

A.7⁶

B.7³

C.7¹²

D.1⁶

Explanation: When dividing exponential expressions with the same base, subtract the exponents: 7⁹⁻³ = 7⁶.

8What is the value of 5⁻²?

A.-10

B.-25

C.1/10

D.1/25

Explanation: A negative exponent indicates the reciprocal of the base raised to the positive exponent: 5⁻² = 1 / 5² = 1/25.

9Express 3.2 × 10⁴ in standard decimal form.

A.320

B.3,200

C.32,000

D.320,000

Explanation: Multiplying 3.2 by 10⁴ (which is 10,000) moves the decimal point 4 places to the right: 3.2 × 10,000 = 32,000.

10Express 0.00045 in scientific notation.

A.4.5 × 10⁻⁵

B.4.5 × 10⁻⁴

C.45 × 10⁻⁵

D.4.5 × 10⁴

Explanation: Move the decimal point 4 places to the right to get 4.5. Since the original number is less than 1, the exponent is negative: 4.5 × 10⁻⁴.

About the Missouri MAP Grade 8 Math Exam

The Missouri Assessment Program (MAP) Grade 8 Mathematics assessment evaluates student mastery of the Missouri Learning Standards (MLS). The exam tests 8th grade mathematical concepts across five primary domains: The Number System (irrational numbers, square/cube roots), Expressions and Equations (exponents, scientific notation, linear equations, systems), Functions (linear vs nonlinear, modeling rate of change), Geometry (transformations, Pythagorean theorem, volume of 3D figures), and Statistics and Probability (scatter plots, line of best fit, two-way tables).

Assessment

Untimed administration in 3 sessions (including a performance event; calculators allowed) with selected-response, technology-enhanced, and constructed-response items

Time Limit

Untimed; DESE estimates 3 sessions (30-50 min, 30-50 min, and a 30-40 min performance event); calculators allowed

Missouri MAP Grade 8 Math Study Tips from Top Performers

1Master the rules of integer exponents and operations in scientific notation.

2Practice solving multi-step linear equations with variables on both sides, including identifying equations with no solution or infinitely many solutions.

3Understand how to find the slope and y-intercept of a linear function from graphs, tables, and word problems.

4Memorize and apply the Pythagorean Theorem ($a^2 + b^2 = c^2$) and volume formulas for cylinders ($V = \pi r^2 h$), cones ($V = \frac{1}{3}\pi r^2 h$), and spheres ($V = \frac{4}{3}\pi r^3$).

5Practice performing coordinate transformations: translations, reflections, rotations about the origin, and dilations.
