Additions - Dot Method _ I - 3 OR MORE SINGLE DIGIT NUMBERS
If the number are more than 2, this method is quite
interesting and very easy for young learners. This is also useful
for mentally retarded children. We can also use this method for
adult education programs. There are no restrictions for this method
HERE'S HOW TO PRACTICE IT
For some individuals the carrying part is difficult.
To eliminate carrying part after every tenth place, the tenth place
is dropped out by putting a dot on the number, where the sum exceeds
to ten or equal to ten. The addition is carried out column by column
in the usual manner from bottom to top or top to bottom.
For 7 + 8 + 6
| 11 |
| 7 |
| 14 |
| +8 |
| +6 |
|
| 21 |
| |
|
| Step 1: |
6 + 8 = 14. Since it is more than 10, put a dot on 8 and the
tens place 1 is dropped out and the units place 4 is carried
forward |
| Step 2: |
The unit place 4 is added to the next number 7. We get 7 +
4 = 11. Since 11 is more than 10, put a dot on 7 and the tens
Place 1 is dropped out and the units place 4 is carried forward |
| Step 3: |
Count the dots. We get 2. Take it as the tens place of the
answer.Hence 7 + 8 + 6 = 21 |
