LESSON PLANNING OF ADDITION AND SUBTRACTION
Subject Mathematics
Grade 2nd
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.
