1. Punctuation Power-Up: The Comma

Commas are powerful tools that help make sentences clear. Let's practice three common comma rules.

• Rule 1: Lists. Use commas to separate three or more items in a list.
  • Example: I need to buy bread, milk, and eggs.
• Rule 2: Introductory Phrases. Use a comma after an introductory word or phrase.
  • Example: After school, I'm going to the park.
• Rule 3: Joining Clauses. Use a comma before a conjunction (for, and, nor, but, or, yet, so) that joins two complete sentences.
  • Example: I wanted to play outside, but it started to rain.

Your Turn: Add the necessary commas to the sentences below.

1. My favorite hobbies are reading drawing and playing video games.

2. Before the movie starts we should get some popcorn drinks and snacks.

3. Suddenly a loud noise echoed from the empty hallway.

4. The sun was shining brightly yet a cool breeze rustled the leaves.

5. If you finish your homework you can watch your favorite show.

Your goal is to describe a creepy, old attic. Your description must create a mysterious atmosphere and include the following elements:

• At least 3 descriptive adjectives (e.g., dusty, forgotten, silent)
• At least 1 simile (a comparison using "like" or "as")
• At least 1 metaphor (a comparison stating one thing is another)

Quick Reminders:

• Simile Example: The silence was as heavy as a blanket.
• Metaphor Example: The single window was a lonely eye staring out at the storm.

Prompt: You push open the heavy attic door and shine your flashlight inside. What do you see? Describe the scene in 3-5 sentences.

4. Creative Writing Starter

Continue the story below. What happens next? Who is there? What is the mood? Write at least one paragraph.

The clock struck twelve, and the lights went out…

5. The Great Debate: Persuasive Paragraphs

Use your persuasive skills to argue both sides of a topic. Remember to use persuasive devices to make your argument stronger.

• Emotive Language: Words that appeal to the reader's emotions (e.g., heart-pounding, magical, devastating).
• Rhetorical Question: A question asked to make a point, not to get an answer (e.g., Isn't it time for a change?).
• Facts/Statistics: Using numbers or expert opinions to support your claim (even if you have to invent a plausible one for this exercise).

Part A: Argue that reading is better than watching TV. Write a short paragraph using at least two different persuasive devices.

Part B: (Challenge!) Now, flip your argument. Write a short paragraph arguing that watching TV is better than reading. Use at least two different persuasive devices.

6. Poetry Prompt: Change

Write a short poem (at least 6 lines) about the theme of change. It can be about anything: the seasons changing, a caterpillar becoming a butterfly, moving to a new school, or a personal feeling. Your poem can rhyme, or it can be free verse.

Brainstorming Ideas: autumn leaves, growing taller, a quiet friend becoming confident, a tadpole to a frog.

3. Descriptive Writing Challenge (Example Answer) The dusty air tasted ancient and forgotten. Cobwebs, like ghostly threads of silk, draped over mountains of old furniture. A single, grimy window was a lonely eye staring out into the night, while the wooden floorboards groaned under my feet with every cautious step.

4. Creative Writing Starter (Example Answer) The clock struck twelve, and the lights went out. A sudden, complete darkness swallowed the room, along with a deafening silence. My heart hammered against my ribs. I froze, listening for anything—a footstep, a breath, the creak of a floorboard. Then, from the far corner of the room, came a soft, scratching sound.

5. The Great Debate: Persuasive Paragraphs (Example Answers)

• Part A (Reading is better): Can anything truly compare to the magic of getting lost in a good book? Unlike the passive experience of TV, reading actively expands your vocabulary and sparks your imagination, allowing you to build entire worlds inside your own mind. Studies show that reading improves concentration in a way that television simply can't. Why settle for watching someone else's story when you can be the director of your own?
• Part B (TV is better): In today's fast-paced world, television offers an immediate and powerful way to experience incredible stories and learn about new cultures. Is there a better way to relax with your family than by sharing a heart-pounding drama or a hilarious comedy? Documentaries can transport you from the depths of the ocean to the far reaches of space in a single evening, providing a rich, visual learning experience that a simple book could never replicate.

6. Poetry Prompt: Change (Example Answer) Green leaf on the branch, Holds on tight in summer sun. Then the cold wind blows. A whisper of red and gold, A final dance, a letting go. New bud waits for spring.
