</div>### 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:**

1. Parallel lines are lines in a plane that never meet, no matter how far they are extended.
2. They are always the same distance apart.
3. Use a whiteboard to draw examples and non-examples.

**Types of Lines (10 minutes)**

**Teach students the difference**

1. Parallel lines : never meet.
2. Perpendicular line: will cross to make right angle
3. 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):**

### Review Questions (5 minutes):

1. What are parallel lines?
2. 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
3. Lines that never meet, no matter how far they are extended, are called \_\_\_\_ lines.

### Follow up Tasks (5 minutes):

1. What is the symbol used to show that two lines are parallel?  
    (Hint: It's like two short straight lines)
2. Can parallel lines exist in three-dimensional space?
3. How can you tell if two lines are parallel using a ruler or set square?

### Expected Learning Outcome:
