| Term | Definition |
|---|---|
| ordered number pair | two numbers, or coordinates, used to locate a point on a coordinate grid |
| variable | a letter or other symbol that represents a number |
| ratio | a comparison by division of two quantities with the same units |
| rate | a comparison by division of two quantities with different units |
| pi 3.14 | the ratio of the circumference of a circle to its diameter |
| formula | a general rule for finding the value of something |
| line graph | a graph in which data points are connected by line segments |
| radius | a line segment from the center of a circle (or sphere) to any point on the circle (or sphere) |
| diameter | a line segment that passes through the center of a circle or sphere and has endpoints on the circle or sphere |
| coordinate | a number used to locate a point on a number line; a point's distance from an origin; one of the numbers in an ordered pair that locates a point on a coordinate grid |
| algebraic expression | an expression that contains a variable |
| circumference | the distance around a circle; its perimeter |
| common factor | a factor of two or more counting numbers |
| equal chance/equally likely | having the same probability |

| greatest common factor (GCF) | the largest factor that two or more counting numbers have in common |
| least common multiple (LCM) | the smallest number that is a multiple of two or more given numbers |
| magnitude | 10 times an amount |
| multiplication counting principle | a strategy for determining the total number of possible outcomes for two or more separate choices |
| prime factorization | a counting number written as a product of prime-number factors |
| probability | a number from 0 through 1 giving the likelihood of an event happening |
| tree diagram | a strategy used to find all outcomes in a probability situation |
