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


Addition/subtraction connection in pictures
Free lesson plan from HomeschoolMath.net

This lesson uses a picture with two different kinds of things to illustrate the addition/subtraction connection. The student either adds those things, or covers one kind of things to subtract them.

Add: How many colored balls?
How many white?

__ + __ = 10

 

Subtract Cover the colored balls.
Write a subtraction sentence.
 

10 − __ = __

  Add:

__ + __ = 7

 
 

Subtract: Cover the colored balls.

7 − __ = __

Example exercises

1.  Make an addition sentence and a subtraction sentence from the same picture.

__ + __ = __

7 − __ = __

__ + __ = __

6 − __ = __

 

__ + __ = __

__ − __ = __

 

__ + __ = __

__ − __ = __

  
2.  In each problem, draw some white and some colored balls to fit the addition sentence.  Then cover the COLORED balls and make a subtraction sentence.

 Add:  7 + 1 = __

Subtract:  __ − __ = __

 Add:  6 + 3 = __

Subtract:  __ − __ = __

 

Add:  9 + 1 = __

Subtract:  __ − __ = __

 

Add:  7 + 2 = __

Subtract:  __ − __ = __

  
3.  Cover colored balls/squares/stars, and write a subtraction sentence to fit the picture.

 

__ − __ = __

__ − __ = __

__ − __ = __

__ − __ = __



4.  Lastly, draw the balls or squares yourself to fit the subtraction sentence.  And, write an addition sentence too.

  

9 − 4 = __

__ + __ = __

 

10 − 5 = __

__ + __ = __

 

14 − 3 = __

__ + __ = __

 

      Compare and write  <  or  >  or  =  in between the expressions.

P.S. ....

 

Check out these short video clips from my favorite band - Rockabilly.US. They play oldies, Elvis, country, and top hits of the 50s and 60s. It's a show with large band, costumes, choreography, little skits, "Kid Kritters", 6 dancing/singing girls, junior dancer troupe, etc.

"Be My Baby"
originally by the Ronettes

Impossible Dream (Elvis song)
Most importantly, the band wants to use the uplifting and energetic music to bring some fun, happiness and encouragement into people's lives. They're doing it selflessly to help others, and don't get paid for any of it themselves. And I admire that!
