Lesson Plan of Addition (4digits with carrying)
Subject Mathematics
Grade III
Students` Learning Outcomes
 Add numbers up to 4digits (with carrying) vertically and horizontally.
Information for Teachers
 To add 4digit numbers (with carrying):

 Firstly add ones. If there are 10 ones or more, then change 10 ones for 1 ten and carry it to the column for tens.



 Secondly ad tens. If there are 10 tens or more, then change 10 tens for 1 hundred and carry it to the column for hundreds.
 Lastly add hundreds. If there are 10 hundreds or more, then change 10 hundreds for 1 thousand and carry it to the column for thousands.

 While teaching the lesson, also consult textbook where and when applicable.
Material / Resources
Writing board, chalk / marker, number flashcards (8122, 8221, 8212,8112), chart (having rules of addition with carrying), Mathematics textbook
Introduction
 Ask the students:

 What did you learn yesterday?
 After their response, write the following questions on the board:



 Call any two students to solve the questions on the board.
 Check the answers and correct the mistakes if any.
 Ask the students to tell the students that if the sum of two numbers exceeds 9, we adopt the procedure of carrying.
 After taking their response, tell the students that if the sum of two numbers exceeds 9, we adopt the procedure of carrying.
 Now write the following question on the board:

 Ask the students:

 Can you add these 4digit numbers?
 Collect their response and solve the question with the help of the students.
 Conclude that the procedure of addition of 2digit and 3digit numbers is applicable to the addition of 4digit numbers.
 Ask the students to tell which method of addition of 4digit numbers.
 Ask the students to tell which method of addition we used in solving these questions.
 After their response, tell the students that this method of addition is called Vertical Method of Addition.
 Tell the students that we are going to learn addition of 4digit numbers (with carrying) using vertical and horizontal methods.

Development
Activity 1
 Display the following chart in front of the class:
 Demonstrate the rules of addition with carrying with the help of this chart.
Activity 2
 Write the following questions on the board: Add 3648 and 5362 vertically.
 Ask the students to solve the question in their notebooks.
 Provide guidance to the students where needed.
 At the end solve the question on the board and ask the students to check their work.
 Appreciate the students having correct answers.
 Facilitates the students requiring further guidance.
Activity 3
 Write the following questions on the board: add 4563 and 3649 horizontally.
 Ask the students to solve the question in their notebooks.
 Place the following number flashcards on the table in front of the class.
 Ask the students to pick the correct number flashcards from the table after solving the question.
 Tell the students that winner of this activity will be the one who first picks the correct number flashcard from the table.
 Display the correct number flashcard after the announcement of the winner.
 Ask the students to clap for the winner.
 Check the answers of the remaining students and facilitate them if necessary.
Sum up / Conclusion
 Revise the rules of carrying of addition of 4digit numbers with the help of chart used in Activity 1.
Assessment
 Ask the following questions to assess the students’ understanding of the concept:
 What did you learn today?
 In what condition, the rule of carrying applies?
 What is meant by horizontal and vertical methods of addition?
 If there are 10 ones or more after adding the ones, then what will you do?
 Collect their feedback and conclude the result.
Follow up
 Ask the students to complete the following questions in their notebooks.
 Find the sum of the smallest and the greatest 4digit numbers using horizontal method of addition.
 Ask the students to solve the questions given in the textbook.
