WIAT Mathematics Composite Subtests 4 — Questions and Answers
Question 1: Which of the following is an example of a task on the WIAT Math Fluency-Subtraction subtest?
- Quickly solving a series of written subtraction problems within a set time (Correct answer)
- Explaining the steps used to borrow across zeros
- Estimating the difference between two large numbers
- Solving multi-step subtraction word problems
Correct answer: Quickly solving a series of written subtraction problems within a set time
The Math Fluency-Subtraction subtest presents written subtraction problems to be completed rapidly within a fixed time limit.
Question 2: What is 3/4 of 200?
- 150 (Correct answer)
- 100
- 175
- 125
Correct answer: 150
3/4 × 200 = 150.
Question 3: A triangle has a base of 10 inches and a height of 6 inches. What is its area?
- 30 in² (Correct answer)
- 60 in²
- 16 in²
- 20 in²
Correct answer: 30 in²
Area of a triangle = (1/2) × base × height = 0.5 × 10 × 6 = 30 in².
Question 4: In WIAT score interpretation, which score best describes how a student performed relative to their own age group?
- Age-based standard score (Correct answer)
- Grade-equivalent score
- Raw score
- Scaled score
Correct answer: Age-based standard score
Age-based standard scores compare the student's performance to others of the same age in the normative sample.
Question 5: A number is divisible by 9 if:
- The sum of its digits is divisible by 9 (Correct answer)
- It ends in 9 or 0
- It is an odd number greater than 9
- It is divisible by 3 but not by 6
Correct answer: The sum of its digits is divisible by 9
The divisibility rule for 9 states that a number is divisible by 9 if the sum of its digits is divisible by 9.
Question 6: On the WIAT, the Mathematics Composite is used primarily to:
- Identify overall mathematics achievement level compared to peers (Correct answer)
- Diagnose specific learning disabilities in isolation
- Measure speed of basic fact retrieval only
- Determine IQ-achievement discrepancy for gifted programs
Correct answer: Identify overall mathematics achievement level compared to peers
The Mathematics Composite provides a broad measure of math achievement relative to same-age or same-grade peers.
Question 7: What is 15% of 80?
- 12 (Correct answer)
- 15
- 10
- 8
Correct answer: 12
15% of 80 = 0.15 × 80 = 12.
