How to do the different steps of the activity?
#The teacher can use this geogebra file to show how the position of centriod is constant in different triangles.
*Developmental Questions:
What kinds of questions you can ask for that activity
#Which type of triangle is this ?
#What is a median ?
What are the student follow-up activities/ questions you can give?
#How do you identify the midpoint of the side ?
#Which is the point of concurrency of medians of the triangle ?
#Identify the position in different triangles.
*Evaluation:
#What is the position of centriod in different triangles ?
*Question Corner:
#Why do you think the centriod always remains in the centre for every type of triangle ?
#What does the centriod indicate ?
#What are the practical applications of the centriod ?
