View source for Quadratic equations introduction to quadratic equation activity 3

__FORCETOC__
=Activity - Understanding quadratic equation geometrically=

==Estimated Time==
Half period (introducing Quadratic Equations)

==Materials/ Resources needed== 

==Prerequisites/Instructions, if any==

==Multimedia resources==

==Website interactives/ links/ simulations/ Geogebra Applets==
Geogebra file created and shared by Ganesha Shettigar Sir, Asst Master, G.H.S Kalavara, Kundapura, Udupi, available [http://geogebratube.org/material/show/id/441793 here]

==Process (How to do the activity)==
#open the Geogebra file
##start with values of a=o, b=0, c=0 
##change value of a to 1 (keeping b=0, c=0 and see what happens)
##change value of c to 1, 2, 3 etc  (keeping a=1, b=0 and see what happens)
##change value of b to 1, 2, 3 etc  (keeping a=1, c=0 and see what happens)
#In each of the above cases, discuss with students the meaning of the curve plotted and how the curve changes on change in values.

==Developmental Questions (What discussion questions)==
Distinction between linear equations and quadratic equations.
#When a=0, what happens?
#The quadratic equation graph is a distribution around x-axis. Can it be around y-axis? For it to be around y-axis how should the equation be?
#what does equal roots mean? with respect to distribution around x-axis?
#what does "c" represent?

==Evaluation (Questions for assessment of the child)==
Discuss the nature of the graph in case of the different values of a, b and c and understand

==Question Corner==
#Does a linear equation (can a linear equation) also have a constant?
