The ideas in this addition lesson are taken from Add & Subtract 2-A ebook. Only a few examples of each problem type are shown; you should make more problems of each kind for the student.


Going over to the next ten
Free lesson plan from Homeschool Math.net

This lesson illustrates how single-digit sums going over 10 can be used when adding a two-digit number and a single-digit number.  For example, knowing what 7 + 8 is helps us add 37 + 8.

1.  Fill the missing addends. 

    If  8 + __ = 10,

then  8 + __ = 11.

    If  6 + __ = 10,

then  6 + __ = 11.

    If  3 + __ = 10,

then  3 + __ = 11.

We need just _____ more to make eleven than to make a ten!

 
2.  What if we already have some tens?  Circle the little cubes like above to make a ten.  Add.

 

        



13 + 9 = ___

 



        


15 + 8 = ___

 


        


17 + 7 = ___

 
        


24 + 7 = ___

 

        

25 + 6 = ___

 


        



37 + 9 = ___

When the ones in the problem go over ten, the answer goes to the next ten.

 

 3.  Continue the patterns.  COMPARE the columns.

8 + 1 = __

8 + 2 = __

8 + 3 = __

8 + 4 = __

8 + __ = __

8 + __ = __

8 + __ = __

   

28 + 1 = __

28 + 2 = __

28 + 3 = __

28 + 4 = __

28 + __ = __

28 + __ = __

28 + __ = __

6 + 2 = __

6 + 3 = __

6 + 4 = __

6 + __ = __

6 + __ = __

6 + __ = __

__ + __ = __

   

36 + 2 = __

36 + 3 = __

36 + 4 = __

36 + __ = __

36 + __ = __

36 + __ = __

__ + __ = __

What is same?  What is different?

 

4.  Add.  Compare the problems!

7 + 8 = __

17 + 8 = __

27 + 8 = __

37 + 8 = __

4 + 9 = __

14 + 9 = __

24 + 9 = __

44 + 9 = __

7 + 9 = __

17 + 9 = __

57 + 9 = __

37 + 9 = __

What is same?  What is different?
5 + 6 = __

15 + 6 = __

75 + 6 = __

25 + 6 = __

8 + 8 = __

18 + 8 = __

58 + 8 = __

88 + 8 = __

7 + 5 = __

17 + 5 = __

47 + 5 = __

27 + 5 = __

 

5.  Add.  For each problem, write the corresponding problem with just the ones digits.

46 + 3 = __

 6 + 3 =  9

32 + 7 = __

__ + __ = __

63 + 8 = __

__ + __ = __

19 + 5 = __

__ + __ = __
