Session 38: Parallel lines

Session Title

Parallel Palooza

Objective

By the end of the lesson, students will be able to:


    1. Define parallel lines


  • Identify and draw parallel lines


  • Distinguish between parallel and non-parallel lines in everyday objects

Concept

Parallel lines -Geometry

Materials Required

    1. Whiteboard and markers


  • Ruler and pencil for each student


  • Chart paper with visuals [Real-life objects (books, railway track images, notebook lines)]


  • Worksheets for practice

Methodology

Activity oriented

Session Duration

 90 Minutes

Intro  Activity  (2520 minutes )


GAME TIME : "Parallel or Not?"


How to Play:


Step 1: Human Lines


Divide students into groups of 4–5.


Ask each group to form two straight lines of students standing side by side, facing the same direction.


Say: "Pretend you are lines on the ground. Are you standing the same distance apart all the way? If yes, you’re parallel lines!"



Step 2: Line Detective


Now change it up! Ask one line to slant slightly or move closer at one end.


Ask the class: "Are they still parallel?"


Encourage students to explain why or why not.



Step 3: Rapid Fire Round


Show quick drawings or hold up objects (e.g., a notebook, scissors, a triangle).


Students shout "Parallel!" or "Not Parallel!"



Main Activity (70 minutes)

Main Topic/ Activity


Explanation    (15 minutes)


Definition and Properties:


Parallel lines are lines in a plane that never meet, no matter how far they are extended.


They are always the same distance apart.


Use a whiteboard to draw examples and non-examples.


Types of  Lines ( 1510 minutes )


Teach students the difference:


Parallel lines : never meet.


Perpendicular line: will cross to make right angle 


Intersecting lines:  cross at one point, but do not make right angle


Shapes with Parallel Lines  (10 minutes )


Basic intro to 2D shapes that have parallel lines:


Rectangle (2 pairs)


Square (2 pairs)


Parallelogram (2 pairs)


Trapezium (1 pair)
