LESSON PLANNING OF ADDITION AND SUBTRACTION

Subject Mathematics

Grade 2^{nd}

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.

- Ask them how many students are there in the class today?
- Ask some students to stand up.
- Ask students to tell that how many students are still sitting?
- Write on the board few simple statements e.g.

- Ask different students about their feedback through discussion.

Development

Activity 1

- Describe the following situation to the students by writing on the board, such as;

- Ask the students;
- 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.

Follow up

- Ask students to collect at least 2 examples from daily life where they need to add and subtract things, e.g.
