| Greatest common factor (GCF) | The greatest factor that two or more numbers have in common. |
| Common factor | A number that is a factor of two or more numbers |
| Prime factorization | A number written as the product of all its prime factors. |
| Factor | A number multiplied by another number to find a product. |
| Least common multiple (LCM) | The least number that is a common multiple of two or more numbers. |
| Equivalent fractions | Fraction that name the same amount or part. |
| Simplest form | A fraction is in simplest form when the numerator and denominator have only 1 as a common factor. |
| Reciprocal | Two numbers are reciprocals of each other if their product equals 1. |
| Multiplicative inverse | A reciprocal of a number that is multiplied by that number resulting in a product of 1. |
| Fraction | A number that names a part of a whole or a part of a group. |

| Line of symmetry | A line that divides a figure into two halves that are reflections of each other. |
| x-axis | The horizontal number line on a coordinate plane. |
| y-axis | The vertical number line on a coordinate plane. |
| x-coordinate | The first number in an ordered pair; tells the distance to move right or left from (0,0). |
| y-coordinate | The second number in an ordered pair; tells the distance to move up or down from (0,0). |
| Quadrants | The four regions of the coordinate plane separated by the x- and y- axis. |
