C
ombinations
-sets containing a certain
					 number of objects selected from another set. The combinations of three items
					 from the set {a, b, c, d} are: {a, b, c,}, {a, b, d}, {a, c, d}, {b, c, d}. {a,
					 b, c} and {b, a, c} are considered to be the same set.
Computational Fluency
-the level of skill
					 reached when a person is able to execute an algorithm or procedure efficiently
					 and correctly.
Coordinate Systems
-systems used to locate
					 points using lines or points.
Expanded Form
-the form of a number
					 written as a sum to show place value. For example, the expanded form of 367 is
					 300 + 60 + 7.
Independent Events
-events that have no
					 influence on each other. For example, flipping "tails" with a coin and rolling
					 a four with a die are independent events.
Manipulatives
-concrete, physical objects
					 used to help illustrate mathematical concepts.
Mental Math
-computations and estimations
					 performed without the aid of paper and pencil.
Model
-simulation of a real object that
					 has explanatory power but that typically differs in size, scale, and/or detail;
					 examples include plan, scheme, structure, or mathematical equation.
Mutually Exclusive Events
-two or more
					 events, each of which precludes all the others. For example, the people voting
					 in a presidential election and the people who are celebrating their fifteenth
					 birthday on that election day are mutually exclusive events.
Outcomes
-results that are possible from
					 an experiment or simulation. For example, the possible outcomes of rolling a
					 six-sided number cube are rolls of 1, 2, 3, 4, 5, and 6.
Permutations
-the ordered arrangements of
					 the elements of a set. For example, the permutations of the list {A, B, C} are
					 (1) {A, B,C}, (2) {A, C, B}, (3) {B, A, C}, (4) {B, C, A}, (5) {C, A, B},and
					 (6) {C, B, A}.
Pictograph
-a visual representation of
					 statistical data that uses pictures to indicate value or quantity.
Picture Graph
-see pictograph.
Polynomial Expression
-a mathematical
					 expression that is the sum of terms, each of which is the product of a constant
					 and a non-negative power of a variable or variables. For example, the
					 expression is a polynomial expression.Polynomial Expression-a mathematical
					 expression that is the sum of terms, each of which is the product of a constant
					 and a non-negative power of a variable or variables. For example, the
					 expression 5 x 7 + 11 x 2
					 + 7 x + (-3)is a polynomial expression.
Precision
-the degree of specificity to
					 which a measurement/value/quantity is determined. For example, "The measurement
					 is precise to the nearest millimeter."
Probability
-a number between 0 and 1,
					 inclusive, which indicates the likelihood of an event occurring. For example,
					 the probability of rolling a 1 on a fair, six-sided number cube is 1/6.
Range
-the absolute difference between the
					 greatest and least value in a set of data. For example, the range of the data
					 set {7, 8, 12, 17, 23} is 16 (23-7).
Rational Number
-any number that can be
					 written as a fraction in which both the numerator is an integer and the
					 denominator is a natural number. For example, 3/7 is a rational number since it
					 can be written as a fraction.
Scatter Plot
-a two-dimensional graph of a
					 collection of points.
Standard Form
-the form in which numbers
					 are traditionally written. For example, 367 is in standard form.
Symbolic Representation
-a representation
					 that uses symbols to model a situation or event. For example, the circumference
					 of a circle is found by multiplying the diameter by pi. The symbolic
					 representation that models this calculation is
C=
[pi]
					 d.
