Warm-Up
What's the Big Picture?
• Display a complex image (e.g., a bustling market or detailed forest) on the board.
• Ask: "If you had to describe this whole picture in just one sentence, what would you say?"
• Goal: Encourage students to think about the 'big idea' without listing every single thing.

Intro
Defining the Concepts (Slides 1-4)
• Main Idea: The heart of the message, the most important point.
• Supporting Details: Facts or examples that prove the main idea.
