Sample Tennessee Comprehensive Assessment Program (TCAP) Grade 8 Mathematics Practice Questions

Try these sample questions to test your Tennessee Comprehensive Assessment Program (TCAP) Grade 8 Mathematics exam readiness. 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.√16
B.3/8
C.√7
D.0.75
Explanation: √7 is an irrational number because 7 is not a perfect square, so its decimal expansion is non-repeating and non-terminating. The other numbers can all be expressed as ratios of integers: √16 = 4, 3/8 = 0.375, and 0.75 = 3/4.
2What is the repeating decimal 0.333... (the digit 3 repeats forever) written as a simplified fraction?
A.3/10
B.3/99
C.1/30
D.1/3
Explanation: Let x = 0.333.... Multiplying both sides by 10 gives 10x = 3.333.... Subtracting x = 0.333... yields 9x = 3, so x = 3/9, which simplifies to 1/3.
3Between which two consecutive integers does √30 lie?
A.4 and 5
B.5 and 6
C.6 and 7
D.7 and 8
Explanation: Since 5^2 = 25 and 6^2 = 36, and 30 lies between 25 and 36, √30 must lie between √25 and √36, which are 5 and 6.
4Simplify the expression 5^3 · 5^4 using the properties of integer exponents.
A.5^12
B.25^7
C.25^12
D.5^7
Explanation: According to the product rule of exponents (a^m · a^n = a^(m+n)), when multiplying powers with the same base, you keep the base and add the exponents: 5^(3+4) = 5^7.
5Simplify 8^9 / 8^3.
A.8^3
B.8^6
C.8^27
D.1^6
Explanation: By the quotient rule of exponents (a^m / a^n = a^(m-n)), subtract the exponent in the denominator from the exponent in the numerator: 8^(9-3) = 8^6.
6Express 0.00045 in scientific notation.
A.4.5 × 10^-3
B.4.5 × 10^-5
C.45 × 10^-5
D.4.5 × 10^-4
Explanation: To write 0.00045 in scientific notation, move the decimal point 4 places to the right to get a coefficient between 1 and 10 (4.5). Moving 4 places right gives an exponent of -4, resulting in 4.5 × 10^-4.
7What is the value of √144?
A.11
B.12
C.14
D.72
Explanation: The square root of 144 is 12 because 12 × 12 = 144.
8Solve for x: x^3 = 64.
A.4
B.8
C.16
D.21.3
Explanation: Taking the cube root of both sides gives x = ∛64 = 4, since 4 × 4 × 4 = 64.
9Car A's distance is described by the proportional equation d = 60t, where d is miles and t is hours. Car B's travel is shown by a graph through the origin that passes through the point (3, 195). Which statement correctly compares the two cars' speeds?
A.Car A is faster because its graph is steeper.
B.The cars travel at the same speed because both graphs pass through the origin.
C.Car B is faster because its unit rate is 65 mph compared with Car A's 60 mph.
D.Car B is faster because 195 is greater than 60.
Explanation: In a proportional relationship the unit rate is the slope of the graph. Car A's equation d = 60t gives a slope of 60 mph. Car B's graph passes through the origin and (3, 195), so its slope is 195 / 3 = 65 mph. Because 65 > 60, Car B is faster.
10What is the slope of the line passing through the origin (0,0) and the point (4, 12)?
A.1/3
B.3
C.4
D.8
Explanation: Slope m is change in y divided by change in x: m = (12 - 0) / (4 - 0) = 12 / 4 = 3.

Tennessee Comprehensive Assessment Program (TCAP) Grade 8 Mathematics Study Tips from Top Performers

1Master exponent rules (a^m * a^n = a^(m+n), (a^m)^n = a^(mn), a^(-n) = 1/a^n) and operations in scientific notation.
2Practice solving multi-step linear equations in one variable and 2x2 systems of equations using substitution and elimination.
3Understand how slope (m) and y-intercept (b) define linear functions in tables, graphs, equations, and real-world scenarios.
4Memorize the Pythagorean Theorem (a^2 + b^2 = c^2) and geometric volume formulas: cylinder (V = pi * r^2 * h), cone (V = 1/3 * pi * r^2 * h), and sphere (V = 4/3 * pi * r^3).
5Convert repeating decimals to rational fractions using algebraic methods (x = 0.777... => 9x = 7 => x = 7/9).
6Analyze scatter plots for positive/negative linear associations and calculate relative frequencies from two-way tables.
