Students` Learning Outcomes

  • Add numbers up to 4-digits (with carrying) vertically and horizontally.

Information for Teachers

  • To add 4-digit 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.

Introduction

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

Addition (4-digits with carrying)

      • 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:

Addition (4-digits with carrying)

  • Ask the students:
      • Can you add these 4-digit numbers?
      • Collect their response and solve the question with the help of the students.
      • Conclude that the procedure of addition of 2-digit and 3-digit numbers is applicable to the addition of 4-digit numbers.
      • Ask the students to tell which method of addition of 4-digit 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 4-digit numbers (with carrying) using vertical and horizontal methods.

Development

Activity 1

  • Display the following chart in front of the class:

Addition (4-digits with carrying)

  • 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.

Addition (4-digits with carrying)

  • 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 4-digit 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.

Addition (4-digits with carrying)

  • Find the sum of the smallest and the greatest 4-digit numbers using horizontal method of addition.
  • Ask the students to solve the questions given in the textbook.
