LESSON PLANNING OF ADDITION AND SUBTRACTION

Subject Mathematics

Students` Learning Outcomes

• Solve simple problems regarding addition and subtraction with carrying / borrowing in mixed form.

Information for Teachers

• Help students to understand statements of questions.
• Key words for addition are; total, altogether, sum of, in all etc.
• Key words for subtraction are; how much left, how much more, difference, etc.
• Help students to write statements i mathematical form.
• In a mixed statement we add things first and subtract later.
• While teaching the lesson, the teacher should also consult textbook at all steps where and when applicable.

Material / Material

Writing board, chalk / marker, duster, textbook

Introduction

Activity 1

• Tell students that today we will apply our understanding of addition and subtraction to solve real life situation.

Development

Activity 1

• Describe the following situation to the students by writing on the board, such as;
• How many cows did Mr. Malik has? (Expected answer would be as; 140)
• How many more cows he purchased? (Expected answer would be as; 43)
• How many cows were there on the farm? (Expected answer would be as; 140 + 43)
• Ask one student to write it on the board in columns and add. (Expected answer would be as; 183)
• How many cows did he sell? (Expected answer would be as; 76)
• How we have to find the remaining cows?
• How will you find? (Expected answer would be as; by subtracting 76 cows from the total cows)
• Ask one students to show subtraction in columns on the board and find the answer. (Expected answer would be as; 107)
• Now ask the students to tell you the similar situations where addition and subtraction are both used.
• In this activity you can change the number.

Activity 2

• Write one mathematical sentence on board such as; 15 + 5 + 40.
• Ask each group to make a story about the numerical statement.
• Give them hints in the form of example;   Amana had Rs. 15, her father gave her Rs. 50 more. Write on the board a numerical sentence (15 + 50 – 40)
• From each group ask one student to share story with remaining class and student from the same group will solve on the board.

Sum up / Conclusion

• Math is related to our daily life.
• We can convert a statement into mathematical form to get the answer.
• Key words for addition are; total, altogether, sum of, in all etc.
• Key words for subtraction are; how much left, how much more, difference etc.

Assessment

• Solve one or two statement questions on the board with the help of the students to assess their understanding.
