Define a sphere  \n2. Define the surface area of a sphere  \n3. Identify the shape of a sphere.  \n4. Calculate the surface area of a sphere.  \nINSTRUCTIONAL RESOURCES: chart of different hemisphere  \nSTEP 1: PRESENTATION:  \nIdentification of students’ prior ideas: the students have a prior knowledge of an orange or an egg.  \nMode: Whole class.  \nTEACHER’S ACTIVITIES:  \nThe teacher introduces the lesson by defining a sphere  \nA sphere is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the center of the sphere, and r is the sphere's radius  \nSTUDENT’S ROLE/ACTIVITIES: The students are made to know the definition of a sphere  \nSTEP 2: EXPLORATION MODE: WHOLE CLASS  \nTEACHER’S ACTIVITIES: The teacher defines the surface area of a sphere  \nThe surface area of a sphere is defined as the region covered by its outer surface in threedimensional space. A Sphere is a three-dimensional solid having a round shape, just like acircle. The formula of total surface area of a sphere in terms of pi (π) is given by:  \nSurface area = 4 π r2 square units.  \nSTUDENT’S ACTIVITY: The students are made to know the formula of the surface area of a sphere.  \nSTEP 3: DISCUSSION MODE: WHOLE CLASS.  \nTEACHERS ACTIVITIES: The teacher Identify the shape of a sphere with some examples.  \nSTEP 4: APPLICATION  \nTEACHER ACTIVITIES: The teacher solve problem on the surface area of a sphere.  \nE,g 1. Calculate the surface area of a sphere if the radius of the hemisphere is 3.5cm Solution: Curved surface area of hemisphere of radius = 4􀟨􀝎2  \nCSA = 2 􀝔 227 􀝔 3.52 = 77c􀝉2  \nSTUDENT’S ACTIVITY: The students copy the example into their notes STEP 5: EVALUATION MODE: GROUP WORK  \nTEACHERS ACTIVITIES: The teacher gives the students some problem to do in group while he goes round to see those who still have problems.  \nE.g. 1 Calculate the surface area of a sphere if the radius of the hemisphere is 25cm Solution: Curved surface area of hemisphere of radius = 2􀟨􀝎2  \nCSA = 2 􀝔 227 􀝔 252 = 3928.57c􀝉2 ASSIGNMENT:  \n1.
