1.	As the students have already read about the place value concept, a quick recapitulation of it will be done by showing a picture (image attached) and they will be asked to identify and answer the questions.
They will be explained that addition means putting two or more things together and counting them all from ones to tens place. 
Then teacher will explain the fact of addition with regrouping that sometimes the sum of the numbers at ones or tens place is more than 9, then we have to regroup.
2.	Explanation of the concept of regrouping will be done by a PPT and students will be asked to listen carefully. In the end of the ppt a worksheet will be given to solve. 
3.	By giving more examples, teacher will explain that while adding if the number is more than 9, i.e. 10 or so on then you can regroup 10 ones into 1 ten and keep the rest as ones .

 For strengthening students knowledge, an activity will be given to students to perform as homework.
Activity - Students will be asked to play a game with their parents or siblings.
They need two dice and roll the dice together. Then students will write both the numbers on paper (first number at ones place and second number at tens place). Then the 2nd person will roll both the dice and similarly write the numbers on paper. After three rounds now student will add all the three 2-digit numbers together.  First they will add numbers at ones place then numbers at tens place. The person who will get the bigger number after addition will be the winner.
