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
 
  
+
  
=
    
 
   Cyan Box  plus     DeepPink Box  equals     Cyan Box   DeepPink Box

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


Here's another example:

1
+
2
=
3
 
  
+
    
=
      
 
   DeepPink Box  plus     RosyBrown Box   Chartreuse Box  equals     DeepPink Box   RosyBrown Box   Chartreuse Box

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


Try this problem.

1
+
3
=
 
 
  
+
      
=
        
 
   DarkTurquoise Box  plus     DarkSlateBlue Box   Goldenrod Box   Empty Box  equals     DarkTurquoise Box   DarkSlateBlue Box   Goldenrod Box   Empty 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.
