The ideas in this addition lesson are taken from Addition 1 ebook. Only a few examples of each problem type are shown; you should make more problems of each kind for the student.

Addition facts for sums with 5 and 6
Free lesson plan from Homeschool Math.net

The ideas and example exercises in this lesson show how you can teach the addition facts where the sum is 5 or 6. Of course similar ideas can be used for other sums as well. The child should memorize the facts.

The video below also shows how we can use this idea (plus many others, such as the 9-trick and doubles) to help children memorize the basic addition facts.

 
What kind of groupings can you make?  Think of ALL the possibilities, and write them down here:
 

Drill

What number is missing?  Don't write the answer down but just think it in your head.  Go over and over again these problems with your teacher or in your head 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

What kind of two groups can you divide six hippos?  Do the grouping and write the addition facts.

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

1 + = 6  2 + = 6 0 + = 6 6 + = 6

4 + = 6 3 + = 6 5 + = 6  0 + = 6

+ 2 = 6 + 0 = 6 + 6 = 6 + 4 = 6

+ 3 = 6 + 1 = 6 + 5 = 6  + 2 = 6

Example problem types

1.  Complete the X's to make 6 or 5 and write the addition sentence.

 
2. What is similar about these problems?

 
3.  Find the missing addend - from memory, not by counting.  Use the addition facts you've learned.
