A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z| Face | A plane figure that serves as one side of a solid. The faces of a cube are squares. |
| Fact Family | A set of facts, each of which relates the same three numbers through addition or subtraction. Examples: 3 + 4 = 7, 4 + 3 = 7, 7 - 4 = 3,7 - 3 = 4. |
| Factor (noun) | A number or expression that is multiplied by another to yield a product. Example: A factor of 32 is 8 because 8 * 4 = 32. |
| Factor (verb) | To express as a product of two or more factors. |
| Factors | The whole numbers that are multiplied to get a product. In 6x3=18, 6 and 3 are factors of 18. |
| Fahrenheit | A temperature scale based on 32º as the freezing point of water and 212° as the normal boiling point of water. |
| Fair Share | The amount that each person receives when something is divided equally. |
| Feet | The plural form of foot. |
| Fixed Distance | A distance is kept constant. |
| Flip | A transformation creating a mirror image of a figure on the opposite side of a line. A flip is also called a reflection. |
| Foot | A customary unit used to measure length; 1 foot = 12 inches. The abbreviation for foot is "ft." |
| Formula | A simple way to display mathematical actions. Sometimes variables are involved. Formulas are also used in science to describe mathematical functions. A mathematical statement, equation, or rule that shows a relationship between two or more quantities. Examples: P=3s (perimeter of an equilateral triangle). D=rt (distance=rate over an amount of time). |
| Four-Digit Number | A number that contains four digits. |
| Fraction | A number that represents part of a whole, part of a set, or a quotient in the form a/bwhich can be read as a divided by b. |
| Frequency Table | A table that shows how often each item, number, or range of numbers occurs in a set of data. |
| Frequency | The number of times an event occurs. |
| Frequency Distribution | An organized display of a set of data that shows how often each different piece of data occurs. |
| Front-End Estimation | Using the leading, or left-most, digits to make an estimate quickly and easily. Example:Using front-end estimation to estimate the sum of 594, 32, and 221, an initial estimate would be 5 + 0 + 2 hundreds or 700. |
| Function | A mathematical relationship between two variables, sets of numbers, or an independent variable and a dependent variable. Every value of the independent variable corresponds to exactly one value of the dependent value. Functions can be used to understand how one quantity varies in relation to (is a function of) changes in the second quantity. For example, there is a functional relationship between the price per pound of a particular type of meat and the total amount paid for ten pounds of that type of meat. You can see that values of one variable determine the values of another. |
| Function Notation | A notation in which a function is named with a letter and the input is shown in parentheses after the function name Example: f(x)=x2+1 represents the function y=x2+1 , where the letter f is the name of the function, and f(x), read as f of x, stands for the output for the input x. |
| Fundamental Counting Principle | The principle that states that all possible outcomes in a sample space can be found by multiplying the number of ways each event can occur. |
