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
 
  
+
  
=
    
 
   Turquoise Box  plus     Goldenrod Box  equals     Turquoise Box   Goldenrod Box

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


Here's another example:

1
+
2
=
3
 
  
+
    
=
      
 
   Goldenrod Box  plus     SaddleBrown Box   DarkSlateBlue Box  equals     Goldenrod Box   SaddleBrown Box   DarkSlateBlue Box

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


Try this problem.

1
+
3
=
 
 
  
+
      
=
        
 
   Fuchsia Box  plus     DarkOrchid Box   BurlyWood Box   Aquamarine Box  equals     Fuchsia Box   DarkOrchid Box   BurlyWood Box   Aquamarine 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.
