Exponent | A small raised number used in exponential notation to tell how many times the base is used as a factor. Example: 52 exponent 52 = 5 * 5 = 25 103 exponent 103 = 10 * 10 * 10 = 1,000 |
Factor | One of two or more numbers that are multiplied to give a product. 3 * 5 = 15 15 * 1 = 15 Factors Product Factors Product |
Factor Rainbow | A way to show factor pairs in a list of all the factors of a number. A factor rainbow can tie used to check whether a list of factors is correct.Factor rainbow for 16: 1 2 4 8 16 |
Number Model | A number sentence expression that models a number story or situation. For example, a number model for the array shown below is 4 * 3 = 12 |
