Geogebra file created and shared by Ganesha Shettigar Sir, Asst Master, G.H.S Kalavara, Kundapura, Udupi, available 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)
Developmental Questions (What discussion questions)
Distinction between linear equations and quadratic equations.
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
