# Solve real life problems involving Addition

## Students` Learning Outcomes

• Solve real life problems involving addition.

### Information for Teachers

• Real life problems mean the situations or problems happening in the real world. • Through real world application, students are able to better comprehend the practical application. • While teaching the lesson, also consult textbook where and when applicable.

### Material / Resources

Writing board, chalk / marker, duster, Mathematics textbook, chart (having the important points to solve real life problems)

### Introduction

• Illustrate the following number story in front of the class: • Ask the students: How can we solve this question?
• After their response, call any student on the board and ask to write the given and required information from the number story. • Tell the students that the word “altogether” means we have to find the total number of stamps collected. So we will do addition.
• Ask any student to solve the question on the board.
• Check the work and tell the students that these types of questions are called real life problems. Also we called them story based questions.
• Tell the students that let us practice different real life problems involving addition (with and without carrying)

### Development

Activity 1

• Display the following chart in front of the class: • Explain each point from the chart with the help of example used in introductory activity.
• At the end, ask any student to repeat that points orally in front of the class.

Activity 2

• Write the following number story on the board: • Read the question and ask the students to tell the given and required information.
• How many men in the town?
• How many women in the town?
• What we have to find?
• How can you solve this question?
• Collect their response and ask them to solve the question in their notebooks.
• Move through the class to check the work and correct the mistakes if any.
• On completion, solve the question on the board. Also introduce the words like ‘total’, ‘sum’, ‘altogether’ so that they could easily understand and solve the question.

Activity 3

• Divide the students in groups of 3 to 4.
• Write the following real life problem on the board: • Ask the students to solve the question in their notebooks using the guidelines explained in Activity 1.
• Check the answer of any student from each group.
• Then ask those students to check the work of remaining students.
• At the end, announce the winner group having the students with more correct answers.
• Appreciate that group and ask the remaining groups to re-check their work and correct the mistakes.

### Sum up / Conclusion

• Students will be asked to:
• Revise the procedure to solve the real life problems of addition with the help of chart used in Activity 1.

### Assessment

• There are 3450 girls and 5698 boys in a school.
• Find the total number of children in a school.
