Addition and Subtraction
The property that states that you can add two or more numbers in any order and get the same sum
Commutative Property of Addition:
A graph that uses pictures to show and compare information
Pictograph
A set of objects arranged in rows and columns
Array
The property that states that when the grouping of factors is changed, the product remains the same. Example: (5x4)x3=5x(4x3)
Associative Property of Multiplication
To find about how many or how much
Estimate
The answer to a subtraction problem
Difference
A part of a map or graph that explains the symbols
Key
The property that states that you can multiply two factors in any order and get the same product
Commutative Property of Multiplication
The property that states that the product of zero and any number is zero. (Example: 34x0=0)
Zero Property of Multiplication
To replace a number with another number that tells about how many or how much (Example: 42 rounds to 40)
Round
The property that states that you can group addends in different ways and still get the same sum
Associative Property of Addition
A table that uses numbers to record data
Frequency Table
A number that is multiplied by another number to find the product (Example: 8x9)
Factors
Groups that have the same number of objects
Equal Groups
A graph that records each piece of data on a number line
Line Plot
The property that states that when you add zero to a number, the result is that number (Example: 17 + 0 = 17)
Identity Property of Addition
A bar graph in which the bars go across from left to right
Horizonal Bar Graph
The answer in a multiplication problem
Product
To combine equal groups to find how many in all; the opposite operation of division
Multiply
A table that uses tally marks to record data
Tally Table
An ordered set of numbers or objects in which the order helps you predict what will come next
Pattern
The numbers placed at fixed distances on a graph to help label the graph
Scale
The property that states that the product of any number and 1 is that number (Example: 17x1=17)
Identity 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
Distributive Property of Multiplication
A bar graph in which the bars go up from bottom to top
Vertical Bar Graph
