Sequence

An Ordered List of Numbers

1  2  3  4  5  6  7  8  9 is a sequence counting by 1


Ordinal Number

Used to Name a Position

(1st, 2nd, 3rd, First, Second,Third)


Algorithm

A Procedure for Getting an Answer

Addition, Subtraction, Multiplication, Division


Inverse Operation

One Operation that Undoes the Other

Subtraction undoes Addition, Division undoes Multiplication


Equation

Number sentence with an "=" sign



4 kinds of Math Stories

Combining, Separating, Equal Groups & Comparing



Commutative Property

2 numbers put together ( added, subtracted, divided or multiplied) that get flipped have the same answer

5+6 = 6+5


Identity Property

Number + 0 = Number



Line Segment

part of a line with two endpoints



Ray

begins at a point and continues without end



Oblique Line

a line segment that is neither horizontal nor vertical; it is diagonal



Number Line

a line that shows numbers in a certain distance from zero



Intergers

counting numbers, negative numbers and zero



Factors

Numbers that are multiplied together

3 x 4 = 12
3 and 4 are multiplied together, so 3 and 4 are FACTORS 

Property of Zero

Number x 0 = 0



Angles

Right, Acute, Obtuse Angle



Plane

a flat surface that extends without end



Polygon

a flat shape that has walls

(triangle, square, circle...)


Vertex (vertices)

Two sides that meet to form and angle



Quadrilateral

a 4 sided polygon



Quotient

The answer to a division problem

6 divided by 2 = 3
so 3 is the quotient of the problem. 

Triangles

Equilateral (all equal)
Isosceles (2 equal) Scalene (0 equal) 


Common Denominator

Fractions that have the same denominator



Expanded Notation

Writing a number with a digit x its place value

(3 x 100) + (2 x 10) + (1 x 1) = 321


Frequency Table

Table that shows how many times things are used



Statistics

The study of data (gathered information)



Cluster

a group of data points that are very close together



Probability

a measure of how likely it is that an event(s) will occur



Proper fraction

A fraction that is less than 1

6/7


Improper Fraction

A fraction that is more than 1

7/6


Exponent

Used to show repeated multiplication



Base

The number that is being multiplied in the exponent problem



Power

The base and the exponent, together



Cubed

Refers to a number to the 3rd power or also a geometric reference (W, D, L)



Squared

Refers to a number to the 2nd power



Prime Number

Any number that is not divisible by an number except 1 and itself evenly



Composite Number

Numbers with more than 2 factors



Array

A rectangular arrangement of numbers or objects om row & columns

A shape that takes up sapce



Parts of a solid

Face (flat surface)
Edge (meeting place of 2 flat surfaces) Vertex (meeting place of the edges) 


Mean

an average



Median

The middle number, when data is arranged in numerical order



Mode

The number that occurs the most when data is gathered



Measures of Central Tendency

Mean, Median, Mode



Spread

How the data is stretched out
