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 open files

Non-digital : paper, pencil, ruler, protractor, compass

Process (How to do the activity)

Procedure:

What are Parallel Lines?
How can you tell that lines are parallel?
Two lines ‘i’ and ‘h’ are parallel to each other
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?

-<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.
