Question | Answer |
---|---|

Associative Property of Addition | The property that states that the way addends are grouped does not change the sum Example: (5 + 9) + 3 = 5 + (9 + 3) 14 + 3 = 5 + 12 17 = 17 |

Associative Property of Multiplication | The property that states that the way factors are grouped does not change the product Example: (2 x 3) x 4 = 2 x (3 x 4) 6 x 4 = 2 x 12 24 = 24 |

Average | The number found by dividing the sum of a set of numbers by the number of addends. See also mean. |

Bar graph | A graph that uses horizontal or vertical bars to display countable data Example: |

Cardinal number | A number that tells how many Examples: 4 puppies93 cents |

Circle graph | A graph the shows how parts of the data are related to the whole and to each other |

Commutative Property of Addition | The property that states that when the order of two or more addends is changed, the sum is the same Example: 4 + 5 = 5 + 4 |

Commutative Property of Multiplication | The property that states that when the order of two or more factors is changed, the product is the same Example: 5 x 7 = 7 x 5 |

Composite number | A whole number having more than two factors Example: Composite Numbers Not Composite NumbersNumber Factors Number Factors4 1, 2, 4 1 16 1, 2, 3, 6 2 1, 28 1, 2, 4, 8 3 1, 39 1, 3, 9 5 1, 5 |

Composite number | A whole number having more than two factors |

Coordinates | The numbers in an ordered pair Example: The coordinates of A are (1, 3). The coordinates of B are (-4, -3). |

Cumulative frequency | A running total of the number of items counted or surveyed |

Ascending | From least to greatest number Example: These numbers are in ascending order. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 |

Descending | From greatest to least number Example: These numbers are in descending order. 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 |

Difference | The answer in a subtraction problem Example: 88 – 5 = 3 – 533 is the difference. |

Digit | Any one of the ten symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 used to write numbers |

Distributive Property of Multiplication | The property that states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products Example: 3 x (4 + 2) = (3 x 4) + (3 x 2) 3 x 6 = 12 + 6 18 = 18 |

Double-bar graph | A bar graph used to compare two similar kinds of data |

Equivalent | Having the same value |

Equivalent decimals | Decimals that name the same amount |

Evaluate | To find the value of a numerical or algebraic expression Example: |

Expanded form | A way to write numbers by showing the value of each digit Examples: 635 = 600 + 30 + 51,479 = 1,000 + 400 + 70 + 9 |

Exponent | A number that shows how many times the base is used as a factor |

Frequency | The number of times an event occurs |

Frequency table | A table that uses numbers to record data about how often something happens |

Histogram | A bar graph that shows the number of times data occur within intervals |

Hundredth | One of one hundred equal parts |

Line graph | A graph that uses a line to show how data change over time |

Acute Triangle | A triangle in which all three angles are acute |
