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
 
  
+
  
=
    
 
   DodgerBlue Box  plus     Magenta Box  equals     DodgerBlue Box   Magenta Box

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


Here's another example:

1
+
2
=
3
 
  
+
    
=
      
 
   Magenta Box  plus     MediumTurquoise Box   SeaGreen Box  equals     Magenta Box   MediumTurquoise Box   SeaGreen Box

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


Try this problem.

1
+
3
=
 
 
  
+
      
=
        
 
   Blue Box  plus     Cyan Box   Goldenrod Box   MediumSlateBlue Box  equals     Blue Box   Cyan Box   Goldenrod Box   MediumSlateBlue 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.
