LESSON PLAN OF SOLVE REAL LIFE PROBLEMS INVOLVING MULTIPLICATION & DIVISION

 LESSON PLANNING OF SOLVE REAL LIFE PROBLEMS INVOLVING MULTIPLICATION & DIVISION

Subject Mathematics

Grade 2nd

Students` Learning Outcomes

  • Solve real life problems involving multiplication and division

Information for Teachers

  • Have the information of multiplicand, multiplier and product.
  • Multiplicand: Number to whom we want to multiply.
  • Multiplier: with which we multiply the number.
  • Product: result of multiplicand and multiplier, e.g. 
  • For multiplication, multiply unit first then tens.
  • Have the understanding of a story and change this story into a mathematical statement.

  • For division divide tens first then units.
  • While teaching this lesson, the teacher should also consult with textbook at all steps where and when applicable.

Material / Resources

Writing board, chalk / marker, duster, match sticks, rubber band, stones etc. fake currency notes (4 sets) of different values, flash cards

Introduction

Activity 1

Ask the following questions: 

Activity 2

  • Divide the class in four groups.
  • Provide each group with 24 stones / match sticks.
  • Ask them to arrange in different groups as many you can and write arrangement.
  • Check their work.

Development

Activity 1

  • Tell the story to the students; 
  • Ask the students to read the story carefully and ask the following question to convert the story into mathematical statement and solve it.
  • How many packets of biscuits did Ali buy? (Expected answer would be as; 4 packets)
  • What is the price of one packet? (Expected answer would be as; Rs.25)
  • What we have to find? (Expected answer would be as; cost of 4 packets)
  • How will you find total cost? (Expected answer would be as; y adding ‘25’ four times)
  • Ask one student to solve on the board. 
  • Help the students to convert / solve 4 packets of Rs. 25 or 4 groups of Rs. 25 or 4 x Rs. 25. We can solve it as first multiply units.
  • Now solve with the help of students (e.g. 4 x 5 = 5 x 4 = 20) 100
  • Rs. 20 = 2 groups of tens so write 0 in unit`s place and 2 tens in ten`s column.
  • Then multiply tens i.e. 4 x 2 = 8 then add 2 tens into 8 tens, we get 10 tens.
  • Total spent = Rs. 100 

Activity 2

  • Divide the class into ‘4’ groups.
  • Tell them a story and ask them to listen, understand and solve with stones by making groups. 
  • There are ‘40’ students in a class. The teacher wants to perform an activity. Teacher asks one of the students (Zara / Ahmed) to arrange them in 5 groups, how many groups will be there?
  • Facilitate them to solve the problem.
  • Ask one of the students to present this work on the bard, if students are unable to solve it, solve with their help. 
  • Number of groups = 8 

Sum up / Conclusion

  • Multiplication is the inverse process of division (e.g. 8 / 4 = 2 is written as 2 x 4= 8)
  • Multiplication is the shortest way to show repeated addition.

  • Division is the shortest way to show repeated subtraction.

Assessment

Ask the following questions.
