| Factor Pair | A set of two numbers that when multiplied together give you a specific number. For example, two factor pairs of 6 are 2, 3 and 6,1. |
| Numerator | The top number in a fraction. It shows how many parts we have. |
| Unit Fractions | A fraction where the top number (the numerator) is 1. These are fractions that can not be reduced any further. |
| Improper Fraction | A fraction where the numerator is greater than or equal to the denominator. Example 6/4 |
| Denominator | The bottom number in a fraction. It shows how many equal parts the item is divided into. |
