     −
Refreshment activity related to language - 15 minutes
+
=== Estimated Time ===
 +
20 minutes
   −
Introduction to Geogebra - 15 minutes
+
=== Prerequisites/Instructions, prior preparations, if any ===
 +
Knowledge about line, line segment
   −
Hands-on Activities in Geogebra on points, lines and segments with demonstration - 30 - 40 minutes
+
=== Materials/ Resources needed ===

=== 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
−
'''Students work:'''
+
# 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).
   −
1. Plot 10 points and Name it as A, B, C, D, E, F, G, H, I, J.
+
=== Evaluation at the end of the activity ===
 +
# What is the difference between parallel and intersecting lines?
 +
# Can parallel lines also be intersecting lines?
 +

   −
2. Draw 5 line segments - AB, BD, DE, FG, AH
+
[[Category:Lines and Angles]]
   −
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.
