Case Evidence: The Mystery in the Treetop
Fiction • 165 Words
Leo zipped his fleece jacket tight against the brisk October wind and scrambled up the wooden ladder into his backyard treehouse. Yesterday afternoon, he had left his grandfather’s brass pocket compass resting on the cedar craft table. Now, the table was completely bare—except for three strange clues: a silver acorn cap, a tuft of gray fur, and a neat little pile of sunflower seeds.
Suddenly, a quick scratch-scratch sound came from the rafters above. Leo held his breath and froze. Two bright, glossy black eyes peeked out from behind an old bundle of dried oak leaves. A long, fluffy gray tail twitched with nervous energy.
The tiny bandit let out a sharp “chitter-chitter!” then dropped a shiny foil gum wrapper right onto Leo’s notebook. In a flash, the creature leaped through the open window frame and scurried straight toward the hollow trunk of the giant maple tree.

Exemplar Answers: Making Inferences (RL.3.1)
1. Who is the "tiny bandit" that visited Leo’s treehouse? What clues helped you figure it out?
2 Points
Clues from the text (Accept any 2+):
- Acorn cap, sunflower seeds, gray fur
- Long, fluffy gray tail & glossy black eyes
- "Chitter-chitter!" sound & tree hollow
My Inference (Animal):
A squirrel (gray squirrel)
Teacher Note: Also accept "chipmunk" if student cites seeds/chittering, but guide toward squirrel due to gray fur, fluffy tail, and high treehouse rafters.
2. Why did the creature take the brass compass and leave a gum wrapper? Explain what this tells you.
2 Points
Exemplar Student Response:
The creature took the compass and left the wrapper because it is attracted to shiny, metallic objects. Both brass and foil sparkle in the light. This tells us the squirrel is curious and likes collecting shiny treasures for its nest, swapping or dropping one item when it spots another.
1 Pt: Connects brass & foil as shiny/sparkly. 1 Pt: Explains animal's hoarding/curious behavior.
Common Misconception Alert: Students often guess a human burglar because of the word "bandit." Prompt them to revisit the physical clues (fur, tail, acorns, seeds) and explain that authors use metaphors ("tiny bandit") to describe animals playfully.
