EXAM QUESTIONS
QUESTION 1
Number Theory
CORRECT ANSWER
The foundation of numbers/number meanings
RATIONALE: The foundation of numbers/number meanings is the correct answer to Number Theory because it
represents the underlying principles and properties that govern the behavior of integers and other whole numbers, such
as divisibility, primality, and congruences. By understanding the inherent nature of numbers, mathematicians can develop
and apply theorems and algorithms that have numerous practical applications in cryptography, coding theory, and other
areas of mathematics and computer science.
QUESTION 2
Classification
CORRECT ANSWER
- Focus on attributes or characteristics
- How are they the same? Different?
- Which ones belong? Don't belong?
- How can we sort this collection?
Trusted by thousands of students and professionals worldwide Page 1 of 27
, RATIONALE: This approach is correct because it outlines the essential steps in the classification process, which involves
analyzing attributes or characteristics to identify similarities and differences between items. By considering how items are
the same, different, and how they can be grouped or sorted, individuals can effectively categorize and organize items
into meaningful classes or categories.
QUESTION 3
Seriation
CORRECT ANSWER
- Focus on attributes then ordering a set of objects according to that attribute
- Ex. Length, space, capacity, mass, height
RATIONALE: Seriation involves arranging objects in a specific order based on a shared characteristic or attribute, such as
length, space, or mass, which requires evaluating and organizing the objects according to that attribute. This process
allows for the identification of patterns or relationships among the objects, making it a fundamental concept in
understanding the structure and organization of data.
QUESTION 4
One-to-One Correspondence (What is it? Examples (3))
CORRECT ANSWER
- Each object must be labeled by a single number word
1. Compare sets of objects
- Are there enough pencils for each student?
2. Compare group of objects (more than, less than, equal to)
- Are there more boys than girls?
3. Matching objects
- Cards to envelopes
RATIONALE: One-to-One Correspondence is a fundamental concept that involves matching each object in one set to
exactly one object in another set, ensuring that every object has a unique partner. This concept is demonstrated in the
provided examples, where labeling objects with single numbers, comparing quantities, and matching objects like cards to
envelopes all rely on establishing a one-to-one relationship between the objects being matched.
QUESTION 5
Patterns
CORRECT ANSWER
1. Recognition on construction of patterns
- ABABABABAB (AB pattern)
- ABBABBABBA (ABB pattern)
- Kinesthetic: Clap/jump/tap
- Manipulatives: Pattern blocks/buttons/multilink cubes
2. Choreographing patterns
3. Name patterns
RATIONALE: This answer correctly identifies the steps involved in recognizing, creating, and understanding patterns,
which are essential skills in mathematics. By breaking down the process into recognition, choreographing, and naming
patterns, the student demonstrates a comprehensive understanding of the concept and its various applications.
QUESTION 6
Trusted by thousands of students and professionals worldwide Page 2 of 27
, Communicative Property
CORRECT ANSWER
The order in which numbers are added or multiplied does not change the answer (i.e. 1+3= 3+1; 5x4=
4x5)
RATIONALE: The concept of the commutative property is based on the idea that numbers can be rearranged without
affecting the outcome of an operation, allowing for flexibility and ease in mathematical calculations. This property holds
true for addition and multiplication because the operation itself doesn't change, regardless of the order in which the
numbers are combined, resulting in the same result.
QUESTION 7
Associative Property
CORRECT ANSWER
- Changing the grouping of numbers will not change the value
- Ex. Addition~ (a+b) + c= a+ (b+c)
- Multiplication~ (axb) x c= a x (bxc)
RATIONALE: The Associative Property is correct because it shows that the order in which we group numbers when
performing operations such as addition or multiplication does not affect the final result, allowing for flexibility in problem-
solving. This property is essential in mathematics as it enables us to simplify complex expressions and calculations by
rearranging the order of operations without changing the outcome.
QUESTION 8
Distributive Property
CORRECT ANSWER
4 (x + 3)= 4x + 12
RATIONALE: The distributive property allows us to distribute a single value (in this case, 4) to each term inside the
parentheses, effectively multiplying it by each individual component (x + 3). By doing so, we break down the original
expression into a more expanded form, which is why 4(x + 3) equals 4x + 12, demonstrating a clear application of the
distributive property.
QUESTION 9
Inverse Property
CORRECT ANSWER
- Using opposites to cancel a value
- Using reciprocals
- Addition and multiplication
- -5 + 5= 0; 14 + -14= 0
- 4/7 x 7/4= 1; 2/3 x 3/2= 1
RATIONALE: The Inverse Property is demonstrated by showing that adding or multiplying a value with its opposite or
reciprocal results in a neutral value, such as 0 or 1, which signifies a return to the original state. This concept illustrates
that each operation has an inverse counterpart that effectively "cancels out" the original value, highlighting the
fundamental principle of the Inverse Property.
