A little bit of everything

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 Example:
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
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 Example:
Data Information collected about people or things
Decimal number A number with one or more digits to the right of the decimal point Example: 3.27
Decimal point A symbol used to separate dollars from cents in money, and the ones place from the tenths place in decimal numbers Example:
Decimal system A system of computation based on the number ten Example:
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 Example:
Equivalent Having the same value Example:
Equivalent decimals Decimals that name the same amount Example: 0.5 = 0.50 = 0.500
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 Example: The exponent is 3, indicating that 8 is used as a factor 3 times.
Frequency The number of times an event occurs
Frequency table A table that uses numbers to record data about how often something happens Example: FREQUENCY TABLEDay Number of Students(Frequency)Monday 15 Tuesday 13 Wednesday 5 Thursday 9 Friday 17
Histogram A bar graph that shows the number of times data occur within intervals Example:
Hundredth One of one hundred equal parts Example:
Line graph A graph that uses a line to show how data change over time Example:

Acute triangle A triangle in which all three angles are acute Examples:
Angle Angle A figure formed by two rays that have a common endpoint Example:
Chord A line segment with its endpoints on a circle Example:

Intersecting lines Lines that cross at exactly one point Example: Line EF intersects line GH.
Isosceles triangle A triangle with two congruent sides Example:
Line A straight path in a plane that goes on forever in opposite directions Example: line AB or line BA
Line segment A part of a line that includes two points, called endpoints, and all of the points between them Example: line segment AB or line segment BA
Line symmetry A figure has line symmetry if a line can separate the figure into two congruent parts Example:
Obtuse angle An angle whose measure is greater than 90° and less than 180° Example:
Obtuse triangle A triangle that has one obtuse angle Example:
Octagon A polygon with eight sides Examples:
Ordered pair A pair of numbers used to locate a point on a coordinate plane; the first number tells how far to move horizontally and the second number tells how far to move vertically Example: (1,2) represents 1 unit to the right of zero and 2 units up.
