Maryland State Standards Mastery-
Questions & Rationales for Math, ELA,
Social Studies, and CCR
## MATHEMATICS (Questions 1-50)
The Revised Maryland College and Career Ready Standards for
Mathematics were adopted by the State Board of Education on July 29,
2025, with full implementation for PreK-Grade 8 in SY 2026-27. The
standards emphasize conceptual understanding, procedural fluency,
and algebraic thinking.
### Algebra and Functions
**Question 1**
Solve for x: 3(x - 4) = 2x + 7
A) x = 19
B) x = 5
C) x = -19
D) x = -5
,**Answer: A) x = 19**
**Rationale:** Distribute: 3x - 12 = 2x + 7. Subtract 2x from both sides:
x - 12 = 7. Add 12 to both sides: x = 19. This assesses algebraic
reasoning and equation-solving skills central to the MCCRS.
**Question 2**
What is the slope of the line passing through points (2, 5) and (6, 13)?
A) 2
B) 4
C) 1/2
D) 8
**Answer: A) 2**
**Rationale:** Slope = (y₂ - y₁)/(x₂ - x₁) = (13 - 5)/(6 - 2) = 8/4 = 2.
Understanding slope as rate of change is essential for algebraic
thinking.
**Question 3**
Which expression is equivalent to (2x³)(3x⁵)?
,A) 6x⁸
B) 6x¹⁵
C) 5x⁸
D) 5x¹⁵
**Answer: A) 6x⁸**
**Rationale:** Multiply coefficients (2 × 3 = 6) and add exponents
when multiplying like bases (3 + 5 = 8). This assesses procedural fluency
with exponent rules.
**Question 4**
Factor completely: x² - 9
A) (x - 3)(x + 3)
B) (x - 3)²
C) (x + 3)²
D) (x - 9)(x + 1)
**Answer: A) (x - 3)(x + 3)**
**Rationale:** This is a difference of squares: a² - b² = (a - b)(a + b).
Factoring is a key algebraic skill emphasized in revised standards.
, **Question 5**
What is the y-intercept of the equation y = -2x + 6?
A) 6
B) -2
C) -6
D) 2
**Answer: A) 6**
**Rationale:** In slope-intercept form (y = mx + b), b represents the y-
intercept. This tests understanding of linear equation components.
**Question 6**
Solve the system: y = 3x - 2 and y = x + 4
A) (3, 7)
B) (2, 4)
C) (1, 1)
D) (4, 10)
