Single Digit + Single Digit not more than 10

1) Ascending Order of numbers from 0 to 10:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

 

2) Descending order of numbers 10 to 0.

10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0

 

3) Addition with Zero (0)

0 + 0 = 0                      5 + 0 = 5

1 + 0 = 1                      6 + 0 = 6

2 + 0 = 2                      7 + 0 = 7

3 + 0 = 3                      8 + 0 = 8

4 + 0 = 4                      9 + 0 = 9

 

KEY POINT

When you add Zero to any number the result will be the same number.

 

Addition with (0) on a Number Line

 

0 + 0 =

1 + 0 =

 

 

4) Addition with One (1)

 

1 + 1 = 2                      6 + 1 = 7

2 + 1 = 3                      7 + 1 = 8

3 + 1 = 4                      8 + 1 = 9

4 + 1 = 5                      9 + 1 = 10

5 + 1 = 6

 

Addition with (1) on a Number Line

 

1 + 1 =

2 + 1 =

 

 

 

5) Addition with Two (2)

    2 + 2 = 4                     6 + 2 = 8

    3 + 2 = 5                     7 + 2 = 9

    4 + 2 = 6                     8 + 2 = 10

    5 + 2 = 7

 

Addition with (2) on a Number Line

2 + 2 =

 

6) Addition with Three (3)

 

3 + 3 = 6

4 + 3 = 7

5 + 3 = 8

6 + 3 = 9

7 + 3 = 10

 

Addition with (3) on a Number Line

 

7) Doubling the original number

 

1 + 1 = 2                     4 + 4 = 8

2 + 2 = 4                     5 + 5 = 10

3 + 3 = 6

 

Ex: 1 + 1 =

 

Assignment:

 

Addition by using Doubling the original number

4 + 4 = 4 + 5 = 3 + 3 = 3 + 4 =

2 + 2 = 2 + 3 =

 

8) Tens Compliment:

9 <-->1  8 <–> 2 7 <–> 3 6 <–> 4 5 <–> 5

Why? 9 + 1 = 1 + 9 = 10 8 + 2 = 2 + 8 = 10 7 + 3 = 3 + 7 = 10 6 + 4 = 4 + 6 = 10 5 + 5 = 10

Fill in the blanks

5 + __ = 9 9 + __ = 9 0 + __ = 3 7 + __ = 8 4 + __ = 7

__ + 2 = 4 __ + 4 = 5 __ + 6 = 9 __ + 0 = 8 __ + 7 = 8
