Percent – a part of a whole expressed in hundredths
Positive rational numbers – the set of numbers that can be expressed as a fraction a/b, where a and b are counting (natural) numbers
Qualitative – a broad subjective description (e.g., The speed of car A is slower than the speed of car B.)
Quantitative – a narrowed objective description associated with a quantity (e.g., The ratio of blue cars to red cars is 6:3; therefore, there are twice as many blue cars as red cars.)
Rate – a multiplicative comparison of two different quantities where the measuring unit is different for each quantity
Ratio– a multiplicative comparison of two quantities
Scale factor – the common multiplicative ratio between pairs of related data which may be represented as a unit rate
Strip diagram – a linear model used to illustrate number relationships
Unit rate – a ratio between two different units where one of the terms is 1
Counting (natural) numbers – the set of positive numbers that begins at one and increases by increments of one each time {1, 2, 3, ..., n}
Integers – the set of counting (natural) numbers, their opposites, and zero {–n, …, –3, –2, –1, 0, 1, 2, 3, ..., n}. The set of integers is denoted by the symbol Z.
Order numbers – to arrange a set of numbers based on their numerical value
Place value – the value of a digit as determined by its location in a number such as ones, tens, hundreds, one thousands, ten thousands, etc.
Rational numbers – the set of numbers that can be expressed as a fraction a/b, where a and b are integers and b ≠ 0. The set of rational numbers is denoted by the symbol Q.
Whole numbers – the set of counting (natural) numbers and zero {0, 1, 2, 3, ..., n}
Fluency– efficient application of procedures with accuracy
Reciprocal – a quantity that is used to multiply by a given quantity which results in the product of one
Absolute value – the distance of a value from zero on a number line
