How the lesson starts: Find Main Idea, Key Details, and Summary

The Pond Post
Tavi the turtle runs The Pond Post, the only newspaper under the lily pads. Every story needs a headline that says what it is mostly about. That's the main idea. Tavi needs your help!
Fitz's story
Here is Fitz the frog's story. Dragonflies are expert hunters of the air. Their huge eyes see in almost every direction. Four strong wings let them hover, dart, and fly backward. A dragonfly grabs bugs in midair. One can eat hundreds of mosquitoes a day.
The big idea on top
Every sentence tells how dragonflies hunt. So the main idea is: dragonflies are expert hunters of the air. Fly backward? That's one cool detail, not the whole story. A main idea must cover every sentence.
