Michigan Grade 8 Math Practice: Functions, Equations, and Geometry

Michigan Grade 8 math practice problems with a clear note on current MDE testing: Grade 8 math/ELA is associated with PSAT 8/9, while Grade 8 M-STEP covers science and social studies.

Many families search for “M-STEP Grade 8 math practice,” but current Michigan assessment materials require a careful correction. Michigan Department of Education materials list M-STEP mathematics for Grades 3-7; Grade 8 students take the PSAT 8/9 for math and English language arts, while Grade 8 M-STEP is used for science and social studies. This article is therefore a Michigan Grade 8 math practice guide, not a claim that Grade 8 math is currently tested through M-STEP.

What Michigan Grade 8 Math Students Should Practice

Grade 8 math shifts students toward algebraic thinking, functions, geometry transformations, and data relationships. A strong review plan should cover these areas:

Domain Practice Focus
The Number System Rational and irrational numbers, decimal expansions, square roots, and approximations.
Expressions and Equations Integer exponents, scientific notation, linear equations, slope, and systems of equations.
Functions Function notation, input-output rules, linear versus nonlinear relationships, and rate of change.
Geometry Translations, rotations, reflections, dilations, congruence, similarity, the Pythagorean theorem, and volume.
Statistics Scatter plots, lines of best fit, patterns of association, and two-way tables.

15 Michigan Grade 8 Math Practice Problems

These are original practice questions written for Grade 8 review.

1. Irrational Numbers. Between which two consecutive whole numbers does √52 lie?

2. Scientific Notation. The distance from Earth to the Sun is about 1.5 × 108 km. The distance from Earth to the Moon is about 3.84 × 105 km. About how many times farther from Earth is the Sun than the Moon?

3. Linear Equation. Solve: 4(2x – 3) = 3(x + 5) – 2.

4. System of Equations. Solve the system: y = 2x + 1 and y = -x + 7.

5. Functions. Which relation is not a function? Explain why.
Relation A: (1, 3), (2, 5), (3, 7), (4, 9)
Relation B: (1, 3), (2, 5), (1, 7), (4, 9)

6. Slope. A line passes through (2, 5) and (6, 13). What is the slope?

7. Linear or Nonlinear. A table has x-values 0, 1, 2, 3 and y-values 1, 3, 9, 27. Is the relationship linear or nonlinear?

8. Translation. Triangle ABC has vertices A(1, 2), B(3, 2), and C(2, 5). It is translated 4 units right and 3 units down. What are the new coordinates?

9. Congruence. Which transformations preserve size and shape: translations, reflections, rotations, dilations?

10. Pythagorean Theorem. A 15-foot ladder leans against a wall. The base is 9 feet from the wall. How high up the wall does the ladder reach?

11. Three-Dimensional Diagonal. A rectangular box measures 6 cm by 8 cm by 10 cm. What is the length of the longest diagonal through the interior? Round to the nearest tenth.

12. Cone Volume. A cone has radius 5 cm and height 12 cm. What is its volume? Use 3.14 for pi.

13. Line of Best Fit. A line of best fit for study hours x and test score y is y = 4x + 55. What score is predicted for 8 hours of study?

14. Two-Way Table. In a survey, 30 of 60 Grade 8 students preferred math. What percentage of Grade 8 students preferred math?

15. Exponent Rules. Simplify: (23 × 2-5) ÷ 2-1.

Answers with Work

  1. Between 7 and 8. 72 = 49 and 82 = 64.
  2. About 3.9 × 102 times. (1.5 × 108) ÷ (3.84 × 105) = (1.5/3.84) × 103 = 3.906 × 102.
  3. x = 5. 8x – 12 = 3x + 13, so 5x = 25.
  4. (2, 5). Set 2x + 1 = -x + 7, so 3x = 6 and x = 2. Then y = 5.
  5. Relation B. The input 1 has two different outputs, 3 and 7.
  6. 2. Slope = (13 – 5)/(6 – 2) = 8/4.
  7. Nonlinear. The y-values do not increase by a constant difference; they multiply by 3 each time.
  8. A'(5, -1), B'(7, -1), C'(6, 2). Add 4 to each x-coordinate and subtract 3 from each y-coordinate.
  9. Translations, reflections, and rotations. Dilations do not necessarily preserve size.
  10. 12 feet. 92 + h2 = 152, so h2 = 144.
  11. 14.1 cm. Interior diagonal = √(62 + 82 + 102) = √200.
  12. 314 cubic cm. V = (1/3)πr2h = (1/3)(3.14)(25)(12).
  13. 87. y = 4(8) + 55.
  14. 50%. 30/60 = 1/2.
  15. 1/2. 23 × 2-5 = 2-2; then 2-2 ÷ 2-1 = 2-1.
