# Lesson Planning of Number Operation (Addition)

Lesson Planning of Number Operation (Addition)

Subject Mathematics

Students` Learning Outcomes

• Add numbers up to four digits (with and without carrying) vertically and horizontally.
• Solve real life problems involving addition.

Information for Teachers

• Students have solved the problem up to 3 digit number with and without carrying.
• They know units, tens, hundred are added in unit, tens and hundred respectively. • Add carry in next place digits.
• Now add thousands in thousands.
• While teaching the lesson, the teacher should also consult textbook at all steps wherein and whenever it is applicable.

Material / Resources

Writing board, chalk/marker, duster, ball frame, balls of different color, Match sticks

Introduction

• Ask students to solve the following questions
•                                                         i)  1+4 + 5 =

ii)  2+ 6 + 2 =

iii)  4 + 6 + 3 =

iv)  7 + 3 + 5 =

v)  6 + 5 + 9 =

vi)  5 + 5 +5 =

Development

Approach

Activity method (demonstration, questioning answering technique, storytelling)

 Activity 1 Tell the story to the students. “Ali has two sons, Ahmad and Aslam. They work in a factory. Ahmad earns Rs 4,522 and Aslam earns Rs 3.466 monthly. Find the total income of both”. Ask from the students to read the story carefully. Ask the following questions to the students. How many sons Ali have? (Expected answer would be as; Two) Where do they work? (Expected answer would be as; in a factory) What is the earning of Ahmad? (Expected answer would be as; Rs 4522) What is the earning of Aslam? (Expected answer would be as; Rs 3466) What we have to find total income? (Expected answer would be as; Rs 4522+ Rs 3466 = Rs 7988) How we will find total income? (Expected answer would be as; will add the both amount) Ask one student to write on the board the Ahmad`s income. Ask another student to write Aslam`s income under the Ahmad`s income as under; Th          H       T       U                              4           5        2         2                           + 3            4       6          6                                                            __________ Ask 3rd students to show the first number on the ball frame. Ask 4th student to show the 2nd number on the ball frame. Ask 5th student to write the number counting total balls on the ball frame. Ask the students to read the number aloud. What is the total income of Ahmad and Aslam?

 Activity 2 Divide the class in four groups. Assign them the work and provide ball frame. G1            G2           G3      G4  5648         6458       4685     2577 +3574       +2757     +4347  +6545   ___________________________ Ask them to solve by discussing in their groups using ball frame. Teacher will facilitate them. Ask them to present their work in front of class.

Sum up / Conclusion
• Teacher will ask what you have learnt to day.(Expected answer would be as; we add unit, tens, hundreds or thousands and then thousands)
• After adding units, tens, hundreds if we get more than 9, 1 is added in the next column as a carry.

Assessment

• Write the story on the board.
• “In a cricket match 1st day came 4568 people and 2ndday 5370 people to see the match, find how many people came altogether”?
• Teacher is also required to involve the students in solving the problems given in the exercise at the end of unit / chapter

• Convert the given mathematical statement into story ad draw ball frame, as;

6378

+2764

• Write it on your note book / chart
