7.) Opposites - Numbers that are the same distance from 0 but on opposites sides of 0.
8.) Integers - The set of whole numbers and their opposites.
9.) Absolute Value - A number's distance from 0 on the number line (always positive)
10.) Coordinate Plane - A two-dimensional space formed by two perpendicular number lines called axes.
11.) Ordered Pair - A pair of numbers (x, y) that describe the location of a point on the coordinate plane.
12.) Origin - The point (0, 0) where the x-axis and y-axis intersect.
13.) X-Coordinate - A point's horizontal distance from the origin along the x-axis.
14.) Y-Coordinate - A point's vertical distance from the origin along the y-axis.

Ratio: A comparison of two numbers by division. (Example: 3 to 1, 3:1, 3/1)
Rate: A ratio that compares two numbers measured in different units.
Unit rate: A rate in which the second quantity in the comparison is one unit. (Example: price per 1 pound or miles per 1 hour)
Proportion: An equation that states that two ratios are equivalent.
Percent: A ratio comparing a number to 100.
Equivalent ratios: Ratios that name the same comparison.
Conversion (convert): a change from one unit to another unit. (Example: yards to feet or pints to gallons)
Reflections: A transformation of a figure that flips the figure across the x-axis or y-axis.
Quadrant: The x-axis and the y-axis divide the coordinate plane into four regions. Each region is a quadrant.
Inequality: a mathematical sentence that shows the relationship between two expressions that are not equal using a sign such as < or >.
1.) Base: The number that is multiplied by itself when it is raised to a certain power.
2.) Exponent: The number that indicates how many times the base is used as a factor.
3.) Expression: A mathematical phrase that contains operations, numbers, and/or variables.
4.) Evaluate: To solve; to find the value of a numerical or algebraic expression.
5.) Equation: Math sentence that shows two equivalent expressions: Algebraic contains variables and numbers. Numerical is numbers only.
6.) Constant: A value that does not change.
7.) Inverse Operation: Operations that undo each other; addition and subtraction, or multiplication and division.
8.) Variable: A symbol used to represent a quantity that can change; an unknown number.
9.) Coefficient: The number that is multiplied by the variable in an algebraic expression/equation.
10.) Term: A known number (constant), a variable, or the product of a known number and a variable.
11.) Distributive Property: Distributing the common factor creates an equivalent expression.
12.) Like Terms: Two or more terms in a variable expression that have the same variable factors.
13.) Dependent Variable: A variable whose value depends on the values of one or more independent variables (Output/y-coordinate).
14.) Independent Variable: A variable whose value determines the value of the other variables (Input/x-coordinate).

Interquartile Range – The difference between the upper and lower quartiles of a set of data.
Lower Quartile - The middle number between the minimum and the median in an ordered set of data.
Upper Quartile - The middle number between the median and the maximum in an ordered set of data.
Statistical Question - Questions with answers involving variability.
Center – Three measures of center are: mean, median, and mode. They usually fall in the middle of the distribution of data.
Mean – The sum of the items in a set of data divided by the number of items in the set; also called the average.
Median – The middle number or the mean (average) of the two middle numbers in an ordered set of data.
Mode – The number or numbers that occur most frequently in a set of data; when all numbers occur with the same frequency, there is no mode.
Range – The difference between the greatest and least values in a data set.
Volume – The number of cubic units needed to fill a given space.
Surface Area - The sum of the areas of the faces of a 3-dimensional figure.
Vertices (Vertex) – An angle of a polygon. The point where two lines intersect.
