=== Prerequisites/Instructions, prior preparations, if any ===
#Knowledge about dimensions, plane figures and solid figures.
#The formulae to find the area of a square and triangles.
#They should know the properties of a pyramid.
===Materials/ Resources needed===
Digital: Laptop, geogebra file, projector and a pointer.
===Process (How to do the activity)===
===Process (How to do the activity)===
*Process :
#The teacher can initially discuss about plane figures, solid figures and pyramids.
What kinds of questions you can ask for that activity
#Reiterate the properties of pyramid.
#Discuss about the types of pyramids based on its base.
What are the student follow-up activities/ questions you can give?
#project the geogebra file, point to parts of pyramid.
#Moving slider, show them the open pyramid so that students can easily comprehend the surface area of it.
#Reiterate that surface area of pyramid would be the sum of area of its base + 4 times the area of its sides in case of a regular pyramid.
*Developmental Questions
#What is a pyramid ?
#Name its parts.
#What are its properties ?
#What shape is its base ?
#How many vertices does it have ?
#What are the shapes of its sides.
#How many edges, faces does it have ?
#What is the formula to find the area of a square ?
#What is the formula to find the area of a triangle ?
#How do you get the perpendicular height of the triangle?
#Do you know any other formula to find the area of the triangle ?
#What would be the area of the pyramid ?
*Evaluation:
#On what factors would the area of a pyramid depend ?
*Question Corner:
#Can we have a generalised formula to find the surface area of all types of pyramids ? Discuss.
