TOPIC: MENSURATION                      GRADE: 8^th

TIME ALLOTED: 20 minute                 SUB TOPIC: Total Surface area of Cuboid

TYPE OF LESSON PLAN: Multimedia Lesson Plan

SUB TOPIC SUMMARY: 

Cuboid is a 3dimension figure (l, b and h) having 6 faces, 8 vertex and 12 edges. All surfaces of cuboid are rectangular in shape. Total surface area of cuboid is sum of area of all six rectangular faces.

A.  PRE TEACHING STAGE (PLANNING STAGE):

OBJECTIVES: After completion of this lesson student will be able to:

COGNITIVE DOMAIN:

Knowledge: recognize the shape and dimension of various objects.

Understanding: Identify face, vertex and edges of an object.

Application: formulate total surface area of cuboid and also its special case.

Analysing: differentiate between the shapes of surfaces of cube and cuboid.

AFFECTIVE DOMAIN:

Evaluating: appreciate the importance of cuboid in real life.

PSYCHOMOTOR DOMAIN:

Creating: calculate questions based on total surface area of cube and cuboid.

INTERVENTIONS FOR TEACHING:

Cultural – Room, Gift box, match box

 ICT – PPT

Teaching Aids: PPT, Recapitulation Questions, Reinforcement Video.

Introducing  P.K. Testing               Announcement of Topic	PT will ask students some questions and show some figures to check their previous knowledge and to link topic with their real life.   Q. What is shape of this paper? Q. What is area of this rectangle? Q. Who am i? ( Riddle) Q. What is total surface area of cuboid?   PT will say, Well Students, today we will try to understand about total surface area of cuboid.	3min                         1min
Exploring (identifying)	First of all PT will show some cuboidal objects like room, gift box, match box and ask students to observe carefully. Is there any shape from which all these cuboids are made from?	2min
Explaining	Now PT will explain that 6 rectangle combine to form cuboid. That 6 rectangle represents the face of cuboid. PT will define Total Surface Area of Cuboid is equal to the sum of the areas of it’s 6 rectangular faces.	3min
Taking Action (Predicting / Formulating / Constructing)	P.T. will say, Let’s calculate the total surface area of this cuboidal room having length (l) , breadth (b) and height(h).   To calculate total surface area PT will calculate area of all 6 faces and add them to get formula of total surface area of cuboid.   After this PT will explain one special case i.e. if l=b=h. then again calculate total surface area.	6min

POST TEACHING STAGE (EVALUATION STAGE):

Q1.   A notepad cube measures 22 inches on each side. Find its Total surface     area? 

   Solution: l=22inches

  Total surface area of notepad= 6 side ×side 

 Total Surface area of notepad = 6 ×484

  Total surface area of notepad = 2,904sq inches.

Q. Find the total surface area of a cuboid having length 4 inches, breadth 6 inches, and height 3 inches?

Solution: l= 4inches

                b = 6inches

                h = 3inches

Total Surface area of cuboid= 2 ( l b +b h +hl)

Total Surface area of cuboid = 2 ( 4×6+6×3+3×4)

Total Surface area of cuboid = 2 × 54

 Total Surface area of cuboid = 108sqinches.

Recapitulation	PT will show video to summarize the topic. mention link here  then Pt will ask some question:   1.Give example of some cuboidal objects? 2. Cuboid has……… no. of faces and they all are ………….. in shape? 3. Are all faces of cuboid rectangular? 4. What is Total Surface area of Cuboid? 5. What is Total Surface area of Cube?
EXTENSION OF LEARNING	Calculate the Surface Area of your respective Mathematics Textbook?
