Grade: 2-a Lesson: S1-L5

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

Examples:

Addition 233 + 260 = _.

Step 1a

Start with the ones (or units) digit. Add 3 and 0, which gives you 3.

Move on to the tens digit. Add 3 and 6, which gives you 9.

Move on to the hundreds digit. Add 2 and 2, which gives you 4.

So the final answer is 493.

Therefore, 233 + 260 = 493.

Explanation: Here, after adding the numbers, the result is 493.

There are 207 balls in one shop. There are 265 balls in another shop. How many balls are there in both shops?

Step 2a

Number of balls in the first shop = 207

Number of balls in the second shop = 265

Total number of balls = Number of balls in the first shop + Number of balls in the second shop

Total number of balls in both shops = 207 + 265 = 472.

Explanation: Here, we added the number of balls from both shops, resulting in a total of 472 balls.
