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
 
  
+
  
=
    
 
   RosyBrown Box  plus     Cyan Box  equals     RosyBrown Box   Cyan Box

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


Here's another example:

1
+
2
=
3
 
  
+
    
=
      
 
   Cyan Box  plus     MediumSpringGreen Box   BurlyWood Box  equals     Cyan Box   MediumSpringGreen Box   BurlyWood Box

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


Try this problem.

1
+
3
=
 
 
  
+
      
=
        
 
   Blue Box  plus     Olive Box   Gold Box   DarkGoldenrod Box  equals     Blue Box   Olive Box   Gold Box   DarkGoldenrod 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.
