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
 
  
+
  
=
    
 
   RoyalBlue Box  plus     DarkViolet Box  equals     RoyalBlue Box   DarkViolet Box

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


Here's another example:

1
+
2
=
3
 
  
+
    
=
      
 
   DarkViolet Box  plus     DarkOrange Box   DarkOrchid Box  equals     DarkViolet Box   DarkOrange Box   DarkOrchid Box

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


Try this problem.

+
3
=
 
 
  
+
      
=
        
 
   OliveDrab Box  plus     SandyBrown Box   Chartreuse Box   DarkTurquoise Box  equals     OliveDrab Box   SandyBrown Box   Chartreuse Box   DarkTurquoise 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.
