| Divisible | A number is divisible by a second number if the second number divides the first with no remainder. |
| Theoretical Probability | List all possible outcomes and compare the number of favorable outcomes to the number of possible outcomes. |
| Composite Numbers | A whole number greater than 1 with more than two factors. |
| Prime Factorization | A composite number written as a product of its prime factors. |
| Factor | A factor is a whole number that divides another whole number with no remainder. |
| Multiple | A multiple of a number is the product of that number and a nonzero whole number. |
| Greatest common factor | the greatest common factor that two or more numbers share. For example; 1, 2, 3, and 6 are common factors of 12 and 30, but 6 is the greatest common factor. |
| Least common multiple | the least multiple that two or more numbers share. Common multiples of 6 and 8 include 24, 48, and 72, but 24 is the least common multiple. |
| Exponent | a number that tells how many times the base number is used as a factor. For example, 34 indicates that the base number 3 is used as a factor 4 times. To determine the value of 34, multiply 3 x 3 x 3 x 3 which would give the result 81. |
| Reciprocal | two numbers whose product is 1, such as 2/3 and 3/2 |
| Variable | a symbol (usually a letter) that stands for a number |
| Equation | a mathematical sentence with an equal sign |
| Proportion | A proportion is an equation stating that two ratios are equal. |
| Solid | a three-dimensional figure |
| Face | flat surface of a solid |
| Cylinder | - three-dimensional figure with two circular, parallel and congruent bases |
| Pyramid | three-dimensional figure with only one base |
| Cone | a three-dimensional figure with one circular base and one vertex |
| Area | the amount of space on one side of an object. (L x W) |
| Prime Numbers | A whole number greater than 1 with exactly two factors, 1 and the number itself. |
| Surface Area | the sum of the area of the faces of a three-dimensional figure |
| Volume | the number of cubic units needed to fill the space inside a three-dimensional figure |
| Experimental Probability | collect data through observations or experiments and compare the number of times an event occurs to the number of experiments. |
| Perimeter | the distance around an object. (add up all the sides) |
