Title: Addition

Grade: 2-a Lesson: S1-L3

Explanation: The best way to understand addition is by looking at some examples.Take turns and read each example for easy understanding.

Examples:

Step 1a

add 200 & 10

Write the numbers one below the other as per the places of the digits.
\$200 + 10\$

$1a$

Explanation: Arrange the numbers as per place values

Step 1b

Start adding from the digits in ones place(0 + 0 = 0).Write the sum 0 under the ones digit.

$1b$

Explanation: Start with the digits in ones column. (0 + 0 = 0)

Step 1c

Add the tens digits(0 + 1 = 1). write the sum 1 in ten’s place.
Now we add hundredth’s place i.e., (2 + 0 = 2).

Therefore, 200 + 10 = 210.

$1c$

Explanation: Add ten’s place.So, it will be 1 + 0 = 1. Now there is no carryover and we can directly write 1 in the ten’s column.
Now we add hundredth’s place i.e., (2 + 0 = 2).

Hence, 200 + 10 = 210
