#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 -+'''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.

−===Objectives===
+=== Objectives ===
−Students will be able to identify parallel and intersecting lines.
−=== Estimated Time ===
+20 minutes
−=== Prerequisites/Instructions, prior preparations, if any ===
+Knowledge about line, line segment
−=== Materials/ Resources needed ===
+Digital: Click here to [[:File:Parallel lines .ggb|open]] files
−Non-digital : paper, pencil, ruler, protractor, compass
−=== Process (How to do the activity) ===
−#How to on/off computer ?
+{{Geogebra|m7gxxkgb}}'''Procedure:'''
−#How to open Geogebra application ?
+# What are Parallel Lines?
−#How to use tools in Geogebra interface?
+# How can you tell that lines are parallel?
−#How to create and Save a file in Geogebra ?
+# Two lines ‘i’ and ‘h’ are parallel to each other
−#How to plot and label points, draw line segments, draw line, draw rays ?
+# Identify parallel lines which do not have a common meeting point in the same plane
−# Identify parallel lines do not intersect if extended till infinite in both the directions.
+# Measure the distance between the lines and identify the equidistance (move point 'G') between the parallel lines
+# Students will use sticks or straws to create parallel line segments. They will prove the line segments are parallel by measuring the distance between the line segments.
+# What are intersecting lines?
+# Identify intersecting lines (two or more) meet only at one point always and also can cross each other at common vertex (which is the point of intersection).
−=== Evaluation at the end of the activity ===
+# What is the difference between parallel and intersecting lines?
+# Can parallel lines also be intersecting lines?
