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
 
  
+
  
=
    
 
   Lavender Box  plus     LimeGreen Box  equals     Lavender Box   LimeGreen Box

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


Here's another example:

1
+
2
=
3
 
  
+
    
=
      
 
   LimeGreen Box  plus     DarkCyan Box   Maroon Box  equals     LimeGreen Box   DarkCyan Box   Maroon Box

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


Try this problem.

+
3
=
 
 
  
+
      
=
        
 
   DeepPink Box  plus     DeepSkyBlue Box   MediumAquamarine Box   MediumPurple Box  equals     DeepPink Box   DeepSkyBlue Box   MediumAquamarine Box   MediumPurple 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
