Basic Addition Lesson 1: Number 1

Welcome to Basic Addition. In this unit, you will learn how to add numbers from one to twelve and also zero. FoxyMath wishes you success!

Here's an easy example:

1
+
1
=
2
 
  
+
  
=
    
 
   MediumVioletRed Box  plus     DarkSlateBlue Box  equals     MediumVioletRed Box   DarkSlateBlue Box

We start with one box, add one box, and now have two boxes.


Here's another example:

1
+
2
=
3
 
  
+
    
=
      
 
   DarkSlateBlue Box  plus     DarkSeaGreen Box   MediumSeaGreen Box  equals     DarkSlateBlue Box   DarkSeaGreen Box   MediumSeaGreen Box

We start with one box, add two boxes, and now have three boxes.


Try this problem.

1
+
3
=
 
 
  
+
      
=
        
 
   Sienna Box  plus     SandyBrown Box   Turquoise Box   DarkOliveGreen Box  equals     Sienna Box   SandyBrown Box   Turquoise Box   DarkOliveGreen Box

We start with one box, add three boxes, and now have four boxes.


In order to do basic addition, you must memorize some equations but fear not: FoxyMath will help you! When you are finished with this lesson, you will know the following equations:

1 + 1 = 2
1 + 2 = 3
1 + 3 = 4
1 + 4 = 5
1 + 5 = 6
1 + 6 = 7
1 + 7 = 8
1 + 8 = 9
1 + 9 = 10
1 + 10 = 11
1 + 11 = 12
1 + 12 = 13

The following exercise will help you learn the above equations and what they mean. Please take your time: take whatever time you need to learn the material.
