, 23:12, 3 October 2021no edit summary
===Objectives===
#To get acquainted with digital tool
#To visualize geometrical figures with real life situations
#Introduce children to the concept of points, line, ray and segments
===Estimated Time===
80 minutes
Refreshment activity related to language - 15 minutes
Introduction to Geogebra - 15 minutes
Hands-on Activities in Geogebra on points, lines and segments with demonstration - 30 - 40 minutes
Worksheet distribution - 5 minutes
===Prerequisites/Instructions, prior preparations, if any===
Prior understanding of Edges, corners and shapes
===Materials/ Resources needed===
*Digital : Computer, Geogebra application, projector.
*Non-digital : Worksheet and pencil.
===Process (How to do the activity)===
'''Teachers work:'''
To demonstrate -
#How to on/off computer ?
#How to open Geogebra application ?
#How to use tools in Geogebra interface?
#How to create and Save a file in Geogebra ?
#How to plot and label points, draw line segments, draw line, draw rays ?
'''Students work:'''
1. Plot 10 points and Name it as A, B, C, D, E, F, G, H, I, J.
2. Draw 5 line segments - AB, BD, DE, FG, AH
3. Draw 5 lines - BC, EF, AE, DG, GI
4. Draw 5 rays - OB, FD, KL, BE, RC
===Developmental questions of the activity===
#Why we use points? What does point indicate?
#Are all points are in the same place?
#Do you think you can draw a complete picture of a line? Why?
#Can you measure the line?
#A minimum of how many points are required to fix a line?
#How many points can be plotted on a line?
#How many segments can be on a line?
#Give examples for points, rays, segments and lines in our day-to-day life.
#How to represent line segments, rays and lines symbolically?
==='''Refreshment activity :'''===
<u>Guess the word</u> :
#Grouping the students(Each group has maximum 3 students)
#One student from each group pickup the word, and give 3 clues in a word to describe the vocabulary word that needs to be guessed by other group members
#The word to be guessed should not be told by the participant to other group members.
