A student is solving a word problem: 'Rosa has 3 boxes. Each box has 12 crayons. How many crayons in all?' Which operation should the student use?
Answer: Multiplication
Combining equal groups (3 groups of 12) requires multiplication: 3 × 12 = 36.
What is the greatest common factor (GCF) of 18 and 24?
Answer: 6
The factors of 18 are 1,2,3,6,9,18 and of 24 are 1,2,3,4,6,8,12,24; the greatest common factor is 6.
A student converts 7/4 to a mixed number. The correct answer is:
Answer: 1 3/4
7 ÷ 4 = 1 remainder 3, so 7/4 = 1 3/4.
On the ParaPro math section, a student must evaluate: 5 + 3 × 2. Using order of operations, the answer is:
Answer: 11
By order of operations (PEMDAS), multiplication is performed before addition: 3 × 2 = 6, then 5 + 6 = 11.
A paraprofessional uses base-ten blocks to help a student understand regrouping in subtraction. This is an example of using:
Answer: Concrete manipulatives
Base-ten blocks are concrete manipulatives that provide a physical, hands-on representation of place value and regrouping.
A student needs to find 25% of 80. Which method is correct?
Answer: 80 ÷ 4 = 20
25% is equivalent to 1/4, so dividing 80 by 4 gives 20.
