A targeted fifth-grade reading intervention lesson using an investigative detective motif to teach students how to identify central ideas and isolate supporting text evidence with tactile color-coded strips and scaffolds.
Stem: The central idea of this case report is that...
2. Cite one exact piece of text evidence that supports this idea:
Stem: According to the text, the author reveals that "..."
3. Connect the clue to the central idea (Your detective reasoning):
Stem: This evidence proves the central idea because it shows that...

PAGE 2 OF 2
1 Phase 1: Case Briefing & Bellringer 5 Minutes
Distribute Evidence Brief Warm Up. Direct students to read the urban fox passage. Guide students to apply Yellow to the opening central idea and Blue to supporting facts. Quick oral review using call-and-response.
2 Phase 2: Direct Modeling (I Do) with Slide Deck 10 Minutes
Display Slides 1–4. Introduce the detective role: "A detective never states a claim without showing physical clues."
Teacher Script: "Look at Slide 4. Notice my Yellow Strip says bees use a waggle dance to communicate. Does that cover the whole text? Yes! Now look at my Blue Strips: 13 shakes per second, and pointing toward flowers. Those are the exact fingerprints that prove my yellow idea!"
Distribute Case File Evidence Worksheet (Page 1). Read "Case #204: Rooftop Pollinators" chorally. Have students cut the 4 strips along the dashed lines.
Key Partner Prompt: "Have detectives test Strip D (farmers market). Ask: Does someone buying honey prove that bees survive better on rooftops? No! That clue is a red herring. Discard Strip D into the discard box."
Students glue Strip A into Zone 1 and Strips B & C into Zones 2 & 3 on Page 2. Then, students complete the 3 written evidence stems in Part 2.
Small Group Conferencing: Circulate and prompt hesitant writers: "Read your Blue Strip aloud. Now put quotation marks around those exact author words."
Partners swap worksheets and use the 3-point Detective Rubric to certify each other's case evidence. Teacher stamps or signs "Case Closed" badges.
Observational Mastery Checklist Record during Phase 4 Conferencing
1. Idea vs. Detail Can student distinguish the overarching roof from an isolated fact?
2. Direct Evidence Citation Does the student cite direct words/statistics using quotation marks?
3. Reasoning Connection Can student articulate how the clue proves the big claim?
Tier 3 Intensive Follow-Up
If student struggles with distractor, provide 2 pre-highlighted strips only (no distractor) before re-introducing 3rd choice.
Intervention Extension / Fast Finishers
Have student author their own "Distractor Strip" for a classmate to detect and eliminate in Case File #204.

ZONE 2: Evidence Clue #1 MATCH: STRIP B
"Urban hives produce up to 20% more honey each season because diverse city gardens bloom from March through October."
ZONE 3: Evidence Clue #2 MATCH: STRIP C
"Rooftop bees stay healthier because urban areas avoid the dangerous chemical pesticides used on rural crops."
DISCARDED DISTRACTOR CLUE (STRIP D): "Citizens enjoy purchasing honey at farmers markets..." Red Herring
Rejection Rationale: While factually in the text, Strip D describes human consumer preferences, not biological reasons why bees thrive in cities. It fails the "Umbrella Test" because it cannot support honeybee survival or hive health.
Part 2: Model Case Report Written Responses CCSS RI.5.1 & RI.5.2 Exemplars
1. Central Idea Statement (Model Response):
"The central idea of this case report is that honeybees are flourishing and producing more honey on city rooftops than in the countryside because cities provide diverse flowering gardens and protection from harmful chemicals."
2. Direct Evidence Citation (Model Response):
"According to the text, the author reveals that “urban hives produce up to twenty percent more honey each season because city flowers remain well-watered by municipal sprinklers.”"
"This evidence proves the central idea because it shows that city resources like regular sprinklers allow flowers to stay alive longer, which directly gives rooftop bees a continuous supply of food that rural bees lack."
