TermDefinitionExample
SubtractionThe mathematical operation of taking one number or quantity away from another to find the difference.If you have 5 apples and eat 2, you perform subtraction to find out how many are left.
MinuendThe starting number or the total quantity from which another number is subtracted.In the problem 7 - 3 = 4, the number 7 is the minuend.
SubtrahendThe number or quantity that is being subtracted or taken away from the minuend.In the problem 7 - 3 = 4, the number 3 is the subtrahend.
DifferenceThe result or answer obtained when one number is subtracted from another.In the problem 7 - 3 = 4, the number 4 is the difference.
Pictorial RepresentationUsing images, drawings, or symbols to visually show numbers or mathematical operations.Drawing 6 circles to represent the...

Basic Subtraction Equation Structure
$Minuend - Subtrahend = Difference$
This rule defines the standard format for writing any subtraction problem. The minuend is the initial quantity, the subtrahend is the quantity being removed, and the difference is the remaining quantity.
Pictorial Subtraction Process
1. Represent the Minuend with pictures. 2. Cross out or remove pictures equal to the Subtrahend. 3. Count the remaining pictures to find the Difference.
This rule outlines the step-by-step visual method for solving subtraction problems with pictures, emphasizing the physical act of removing items from a group to find the answer.
Order Matters in Subtraction (Non-Commutativity)
For any two distinct numbers $a$ and $b$, $a - b \neq b - a$.
This rule highlights that th...

Challenging
In any pictorial subtraction problem where the subtrahend is greater than zero, what is the relationship between the minuend and the difference?
A.The minuend is always equal to the difference.
B.The minuend is always smaller than the difference.
C.The minuend is always larger than the difference.
D.There is no consistent relationship between the minuend and the difference.
Challenging
You see a finished subtraction picture. There are 3 squares that are NOT crossed out, and 6 squares that ARE crossed out. What was the original subtraction equation being modeled?
A.6 - 3 = 3
B.9 - 3 = 6
C.9 - 6 = 3
D.6 + 3 = 9
Challenging
A classmate states, 'To solve any subtraction problem with pictures, you just draw two groups of objects and cross out the smaller group.' Evaluate this statement.
A.This is always correct.
B.This is incorrect; you should always cross out the larger group.
C.This is incorrect; you must draw one group representing the difference first.
D.This is incorrect; you must draw one group representing the minuend, then cross out a number of items equal to the subtrahend.
