Competency 0001
Number and Operations

1. Given that p and q are distinct prime numbers greater than 2, which of the following could be a whole number?

  1. 2p over q

  2. p squared over q

  3. p over q plus 1

  4. p plus one over q minus one
Correct Response: D. This question requires the examinee to apply number theory concepts. Prime numbers are numbers whose only factors are the number 1 and the number itself. Choose prime numbers and test them in each of the expressions. For example, if p = 7 and q = 5, then the only expression that represents a whole number is choice D: 7 + 1 over 5 - 1 = 2.

Competency 0002
Operations and Algebraic Thinking

2. Use the diagram below to answer the question that follows.

An artist creates a cube using a piece of clay. The artist then cuts the cube in half to make two congruent rectangular solids, as shown in the diagram. Which of the following is the ratio of the surface area of the original cube to the total surface area of the resulting rectangular solids?

  1. 1:2
  2. 2:3
  3. 3:4
  4. 5:6
Correct Response: C. This question requires the examinee to solve unit-rate problems including those involving ratios of areas. Since the original solid is a cube, its surface area is 6 times the area of one face. Suppose the area of one face is 1 square unit, then the original surface area is 6 square units. By cutting the cube in half, the artist has created two new surfaces, each with area 1 square unit, and kept the other surfaces the same. Thus the total area of the two solids is 8 square units. The ratio of the original surface area to the new total surface area is 6:8 or 3:4.

Competency 0003
Measurement, Geometry, and Data

3. Use the diagram below to answer the question that follows.

The diagram represents a method for estimating BC, the width of a river. Given that AB = 50 feet, CD = 100 feet, and BE = 30 feet, which of the following is the best estimate for BC?

  1. 60 feet
  2. 80 feet
  3. 117 feet
  4. 167 feet
Correct Response: C. This question requires the examinee to solve problems involving similarity. ΔABE is similar to ΔACD because their corresponding angles are congruent. Therefore the corresponding sides of the two triangles are proportional: 50 over AC = 30 over 100 , and 30(AC) = 5000. To the nearest foot, AC is 167, so BC is 167 50 or 117 feet.

Competency 0004
Instruction in Mathematics

4. Use the diagram below to answer the question that follows.

A teacher places a set of blocks on a table and asks a child how many blocks there are. The child points to each block while saying the numbers in the proper sequence from one through five. When asked again how many blocks there are, the child responds by counting the number of blocks again. Given this evidence, which question could the teacher ask to help the child connect counting to cardinality?

  1. How many cones, boxes, and balls are there?
  2. How is the last number name you said related to the number of blocks?
  3. How many different types of shapes are there?
  4. How is the first block counted similar to the last block counted?
Correct Response: B. This question requires the examinee to apply strategies for teaching counting and cardinality. The number of objects in a group is the cardinal number, or cardinality, of the group. When counting the objects in a group, the last number named is the number of objects in the group.
