RULE | method for performing a mathematical operation |

SIGN | A conventional figure or device that stands for a word, phrase, or operation; a symbol, as in mathematics a device that stands for a word, phrase, or operation; a symbol in mathematics |

FACES | A flat side of a solid figure. e.g. a cube has 6 faces |

GRAPH | a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles. |

EXPLAIN | to assign a meaning to; interpret; o make known in detail |

PATTERN BLOCKS | geometric manipulatives |

MEASURE | to estimate the relative amount, value, etc., of, by comparison with some standard |

EVENLY | equal in measure or quantity |

OBJECT | an object is just an element of the set of things named objects in the definition of a category ("a category is a collection of objects together with arrows between those objects..."). |

LEAST | smallest in size, amount, degree, etc.; slightes |

GROUP | any collection or assemblage of persons or things; cluster; aggregation: |

NUMBER LINE | A line on which real numbers are assigned to points. points to the left of 0 are negative and points to the right are positive. |

MODEL | a representation, generally in miniature, to show the construction or appearance of something. |

CYLINDER | A Three dimensional shape with a parallel circle and each end and joined by a curved surface. |

SQUARE UNIT | A unit for measuring areas, such as square foot, square meter etc. |

EQUATION | a math sentence using the equals sign between 2 expressions naming the same number |

SOLVE | to work out the answer or solution to (a mathematical problem) |

GEOMETRIC | of or pertaining to geometry;resembling figures used in geometry;a geometric pattern, design, etc |

SYMMETRY | Two halves which match perfectly. 3 kinds of symmetry-line or reflectional, Plane, and Point |

LINE SEGMENT | A straight path that has a beginning and an end - endpoints. part of a line |

ORDERED PAIRS | a set of two numbers in which the order has an agreed upon meaning. Such as the cartesian coordinates (x, y), where it is agreed that the first coordinate represents the horizontal position, and the second coordinate represents the vertical position |

COORDINATE | The ordered pair of a number associated with a point on a graph; (x,y) |

MEAN | The mean is the same as the average. Add up the series of numbers and divide the sum by the number of values. |

MEDIAN | The Median is the 'middle value' in your list or series of numbers |

MODE | The mode in a list of numbers refers to the list of numbers that occur most frequently. A trick to remember this one is to remember that mode starts with the same first two letters that most does. |

RANGE | The difference between the greatest number and the least number in a set of data |

POINT | The simplest figure in geometry, pictured by a dot |

FIGURE | A set of points. Such a set can be line segments, triangles, or other polygons |

CENTIMETER | A centimeter is a unit of length in the metric system. It is one hundredth of a meter 1cm = 1/100 m |

EXACTLY | in an exact manner; accurately or precisely |

PYRAMID | A polyhedron with a base that is a polygonal region and having 3 or more triangular faces |

DECIMAL | A number with a decimal point in it, such as 5.36, 0.04, or 0.3 |

PROBABILITY | The ratio of the number of outcomes favoring an event to the total number of possible outcomes |

METER | The basic unit of length in the metric system of measurement. Most doorways are about 2 meters high |

PERCENT | A ratio of a number to 100. "per hundred" or "out of 100" |

PERIMETER | The total distance around the outside of a polygon. The total distance around is obtained by adding tegether the units of measure from each side. |

RIGHT TRIANGLE | A triangle having one angle equal to 90°. |

SCALE | The horizontal scale across the bottom and the vertical scale along the side of a graph tell us how much or how many. |

DIGITs | Digits are making reference to numerals. 176 is a 3 digit number. |

CUBE | A rectangular prism having 6 square faces |

POLYGON | Line segments joined together to form a closed figure. Rectangles, squares, pentagons are all examples of polygons. |

EXPANDED FORM | Expanded form shows the number expanded into an addition statement. The expanded form of 495,786 is 400,000 + 90,000 + 5,000 + 700 + 80 + 6. |

TRUE | being in accordance with the actual state or conditions; conforming to reality or fact; not false |

3-DIMENSIONAL | An object that has height, width and depth, like any object in the real world. Example: your body is three-dimensional. |

EQUIVALENT | Equal in amount, force, or value |

COMMON MULTIPLE | A number that is a multiple of two or more numbers |
