Introduction
This assessment prepares candidates for the Illinois Licensure Testing System (ILTS) Middle Grades
Mathematics examination, which evaluates proficiency essential for teaching mathematics at the 5-8 grade
level. The exam assesses critical skills including number operations, algebraic reasoning, geometric analysis,
data interpretation, and mathematical pedagogy. All questions are multiple-choice format, featuring both
direct knowledge queries and scenario-based problems that mirror real classroom situations. The test
emphasizes practical application of mathematical concepts and informed decision-making in educational
contexts, ensuring candidates can effectively support student learning across diverse mathematical domains.
,Section One: Questions 1–100
Question 1
Which of the following best describes the primary purpose of using mathematical discourse in the classroom?
A. To increase the speed of student problem-solving
B. To help students articulate and refine their mathematical reasoning
C. To reduce the need for written homework assignments
D. To standardize student answers across all classes
🟢 B. To help students articulate and refine their mathematical reasoning
🔴 RATIONALE: Mathematical discourse enables students to explain their thinking, critique others' reasoning,
and develop deeper conceptual understanding through verbalization of mathematical ideas.
Question 2
A student claims that 3/4 + 2/5 = 5/9. What is the most likely error in this student's reasoning?
A. The student added numerators and denominators separately
B. The student confused addition with multiplication
C. The student used the wrong common denominator
D. The student subtracted instead of added
🟢 A. The student added numerators and denominators separately
, 🔴 RATIONALE: The student incorrectly added 3+2=5 for the numerator and 4+5=9 for the denominator,
which is a common fraction addition error.
Question 3
Which graph best represents the function y = 2x + 3?
A. A line with slope 2 and y-intercept 3
B. A line with slope 3 and y-intercept 2
C. A parabola opening upward
D. A line with slope -2 and y-intercept 3
🟢 A. A line with slope 2 and y-intercept 3
🔴 RATIONALE: In the linear equation y = mx + b, m represents the slope (2) and b represents the y-intercept
(3).
Question 4
What is the value of √144?
A. 10
B. 11
C. 12
D. 13
🟢 C. 12
