Addition facts for sum with 5


Number Bonds 5
The ideas and example exercises in this lesson show how you can teach the addition facts where the sum is 5. Of course similar ideas can be used for other sums as well. The child should memorize the facts .


You can divide five elephants into groups of two and three:
|    5 = 2 + 3
Also, you can divide five elephants into groups of zero and five:
  |   5 = 0 + 5



What number is missing?  Don't write the answer down but just think it in your head.  Go over and over again these problems  until you know the missing numbers by heart.


1 + = 5  2 + = 5
0 + = 5 
           4 + = 5 3 + = 5
5 + = 5 
           + 2 = 5 + 0 = 5
+ 4 = 5
           + 3 = 5 + 1 = 5
+ 5 = 5
