PROBLEMS OF PERIMETER / AREA

by

LESSON PLANNING OF SOLVE APPROPRIATE PROBLEMS OF PERIMETER AND AREA Subject Mathematics Grade 5th

Students` Learning Outcomes

  • The students will be able to:

o   Solve appropriate problems of perimeter and area.

Information for Teachers

  • Total measurement of the boundary of any closed shape is called perimeter.

 

  • Units of perimeter can be measured in meter, centimeter and kilometre.
  • Perimeter can be found by adding all the sides of a shape.
  • Perimeter of square = 4 x length of one side.

 

 

  • Area of a square = 2 x length of one side.

 

 

  • Perimeter of rectangle = 2(Length +Breadth)
  • Area of rectangle = Length x Breadth

 

 

  • The area of any closed figure represents the region covered by that shape.

 

Material / Resources

Writing board, chalk / marker, duster, pencil, paper, ruler, scissors, chart paper cutouts with shapes and sizes and text book

Introduction

  • Half coloured piece of two same size bread`s slices of rectangle shape was given to two children as mentioned in following figures.

 

  • The child who got coloured piece as per fig (i) complaint that the received small piece,
  • Now ask from students;

 

o   Why coloured piece of fig (i) is looking larger?

o   Is the area of both coloured pieces same? (Yes)

Development

Activity 1

  • Tell them that today we are going to discuss perimeter and area by solving real life problems.

 

 

Sum up / Conclusion

  • Tell the students that today we have discussed perimeter and area in variety of ways. Repeat the key points of today`s lecture before end e.g. square units, area, perimeter etc.

o   Perimeter is the distance around a closed figure.

o   Area is the space or region occupied by a closed figure.

o   Term area is used for example to carpet the whole room.

o   Term perimeter is used for example to put a fence around the garden.

  • If they find any difficulty in understanding the concept of area and perimeter then Give them more examples to make them understand the concepts of area and perimeter.
