 Intro Activity (20 minutes): 

 "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 (60 minutes): 

 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 (10 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) 

 

 WORKSHEET (10 minutes): 

 

 ANGLES (15 minutes) (Draw the picture given below on a chart) 

 

 Review Questions (5 minutes): 

 

 What are parallel lines? 

 Which of the following are examples of parallel lines? a) Railway tracks b) The sides of a triangle c) Clock hands at 3 o’clock 

 Lines that never meet, no matter how far they are extended, are called ____ lines. 

 

 Follow up Tasks (5 minutes): 

 

 What is the symbol used to show that two lines are parallel? (Hint: It's like two short straight lines) 

 Can parallel lines exist in three-dimensional space? 

 How can you tell if two lines are parallel using a ruler or set square?
