Solve the system: y = 2x + 1 y = x + 4 What is x?
LEAP 2025 Grade 8 Math sample questions with answers
Questions in the test's style, each with the answer and an explanation. Open the answer once your child has tried the question.
Question 1 · Grade 8 Math · Standard 8.EE.C.8
Solve the system: y = 2x + 1 y = x + 4 What is x?
- A.1
- B.2
- C.3
- D.4
Show the answer and explanation
Answer: C. 3
Set equal: 2x + 1 = x + 4. Subtract x: x + 1 = 4. So x = 3. (Then y = 7.)
Question 2 · Grade 8 Math · Standard 8.G.B.7
A TV screen is 36 inches wide and 27 inches tall. What is the diagonal measurement?
- A.40 inches
- B.45 inches
- C.50 inches
- D.63 inches
Show the answer and explanation
Answer: B. 45 inches
36² + 27² = 1296 + 729 = 2025. √2025 = 45 inches.
Question 3 · Grade 8 Math · Standard 8.SP.A.2
A line of best fit has equation y = 2x + 10. What does the slope (2) represent?
- A.The starting value
- B.The rate of change
- C.The y-intercept
- D.The total value
Show the answer and explanation
Answer: B. The rate of change
In y = mx + b, m (slope) = rate of change. For every 1 unit increase in x, y increases by 2.
About the LEAP 2025 Grade 8 Math Test
Grade 8 is the last middle-grades LEAP math test and the mathematical bridge to high school: the content is built around functions and linear relationships, the foundation of Algebra I. The scoring frame is the same as every LEAP grade — "Mastery" is the on-grade-level target, "Basic" is below it — and statewide only about a third of Louisiana students in grades 3-8 reach Mastery in math.
The test measures the Louisiana Student Standards, reported as Major Content, Additional & Supporting Content, and Mathematical Reasoning & Modeling. The signature grade-8 skills are understanding functions, graphing and interpreting linear relationships (slope and intercept), the Pythagorean theorem, and exponents and scientific notation.
Statewide in 2026, 34% of Louisiana students (grades 3-8) reached Mastery or above in math.
LEAP is given online. Grade 8 is the one grade where a scientific calculator (no graphing, no CAS) is allowed on Sessions 2 and 3; Session 1 is calculator-free. A math reference sheet is provided.
Mastery + Advanced = on grade level. 'Basic' is BELOW Mastery. LDOE's headline figure is by subject across grades 3-8.

What's On The LEAP 2025 Grade 8 Math Test
Grade 8 math on LEAP is reported in three categories, with functions and linear relationships as the defining content. LDOE's grade 8 assessment guide gives the points: Major Content 27, Additional & Supporting Content 9, and Mathematical Reasoning & Modeling 19, out of 55.
| Reporting Category | What's Tested |
|---|---|
| Major Content (27 of 55 points) | Functions and linear relationships (slope, rate of change), solving linear equations and systems, exponents, roots, and scientific notation, plus transformations and the Pythagorean theorem. The core of grade 8 and the on-ramp to Algebra I. |
| Additional & Supporting Content (9 of 55 points) | Volume of cylinders, cones, and spheres, irrational numbers, and analyzing bivariate data. |
| Mathematical Reasoning & Modeling (19 of 55 points) | Type II and Type III tasks: explaining and justifying answers, critiquing reasoning, and modeling real-world problems — a LEAP emphasis. |
Test Format — What Your Child Will See
- ●Content centers on functions and linear relationships — the on-ramp to Algebra I.
- ●Grade 8 is the one LEAP grade with a scientific calculator (Sessions 2-3).
- ●"Mastery" is the target; "Basic" is below it.
What Louisiana Parents Should Know About Grade 8 Math
- 1
Master functions and linear graphs — the heart of grade 8 and Algebra I. Reading slope and intercept off a graph is the key skill.
- 2
Lock in the Pythagorean theorem and exponent rules — concrete, high-frequency, reliable points.
- 3
Practice with and without a calculator: Session 1 is calculator-free, Sessions 2-3 allow a scientific calculator.
- 4
Aim for Mastery; know 'Basic' is below grade level.
LEAP 2025 Grade 8 Math — Frequently Asked Questions
