Pedagogical Notes
Scripted Think-Aloud (Slide 6)
Teacher: “I just read paragraph 2 about rescue dogs finding lost hikers in snow. I ask myself: Is this whole text only about snowy mountains? No! That’s just one raindrop—one key detail! The big umbrella is that dogs have super smelling abilities that help them do many jobs .”
Prompting Students: “Turn to your neighbor and tell them: Why isn't 'airports have sniffer dogs' the main idea? How does it support the big umbrella instead?”
Common Misconceptions & Corrections
Misconception: Confusing a cool detail for the main idea.
Correction: “Ask yourself: Does this sentence cover everything in the passage, or just one part? If it's just one part, it's a detail raindrop!”
Misconception: Answering from background memory without text evidence.
Correction: “You might know lots of fun dog facts, but detective rules require proof! Put your finger on the exact words in paragraph 1 or 2.”

Amazing Guinea Pigs: Perfect Pocket Pets
1 Guinea pigs are wonderful, gentle pets that make sweet companions for families. Even though they are called "pigs," they are actually friendly rodents with round bodies, soft fur, and no tails at all!
2 These little animals have special ways of communicating with their owners. When a guinea pig feels happy or excited to eat, it makes a high-pitched squeaking noise called a "wheek." They also do a happy hop called "popcorning," where they jump straight into the air and twist!
3 Guinea pigs need thoughtful care to stay healthy and safe. They eat fresh hay and leafy greens every day, and they love having a soft hideout where they can rest. Because they are social pets, they are happiest when living with another guinea pig friend.
