Ratios and Proportions
mathematical comparison of two or more quantities. Can be written as a:b, a to b, or a/b
Ratio
The value that appears most frequently in the data set
Mode
the total amount of 2D space, surface, or region enclosed within a flat shape's boundary
Area
a whole number that can be positive, negative, or zero, and does not include any fractional or decimal parts.
Integer
A number being multiplied by a variable, EX: the 4 in the expression "4x"
Coefficient
A rate that compares two different quantities where the second quantity (denominator) is reduced to exactly one, such as "miles per hour" or "dollars per pound".
Unit Rate
The middle value in an ordered data set.
Median
the total amount of 3D space an object occupies
Volume
the distance of a number from zero on a number line, regardless of direction, and is always positive or zero
Absolute Value
a letter used in place of an unknown number in equations, expressions, and formulas.
Variable
A specific type of ratio that compares two quantities measured in different units
Rate
the difference between the highest and lowest values in a data set, representing the spread of data. (Spread, variation, variability)
Range
the total, two-dimensional space occupied by all the outer faces or surfaces of a 3D object.
Surface Area
the value the same distance from zero on a number line but on the opposite side.
Opposite
a value, number, or symbol that remains fixed and unchanging throughout a particular problem, equation, or expression
Constant
Two numbers that represent the same value.
Equivalent
The average of a set of data
Mean
the side of a 2D shape (like a triangle or rectangle) or the bottom face of a 3D solid (like a prism or cone) upon which the figure "sits" or is measured.
Base
a value less than zero,
Negative Integer
algebraic expressions that contain the exact same variables raised to the same powers, even if their numerical coefficients differ
Like Terms
A ratio or fraction that represents a part of a whole out of 100. "Per Hundred"
Percent
a measure of variability that describes the spread of the middle 50% of a data set. The distance between the first quartile (Q1) and the third quartile (Q3).
Interquartile Range
the perpendicular measurement from a shape's base to its top, highest vertex, or opposite side
Height
the largest positive integer that divides two or more numbers evenly without leaving a remainder
Greatest Common Factor
a mathematical statement asserting that two expressions are equal
Equation
