TOPIC TO PROOF
Hunting for Text Clues
How to find exact facts from a text that prove your topic sentence is true!
Today's Mission: Read like a detective, spot the proof, and leave no clue behind.
The Topic Sentence Is the Boss
Rule #1
What It Does
The topic sentence is the first sentence of your paragraph.
It announces your main idea or claim. It tells the reader what the entire paragraph will prove!
Example Topic Sentence:
"Chameleons have amazing superpowers that protect them from danger."
The Detective Question
Once you write or read the topic sentence, ask yourself:
"How does the text PROVE this is true?"
You cannot just guess! You must pull real facts straight from the reading.
A topic sentence makes the claim • Text clues prove the claim!
What Counts as Text Evidence?
The 3 Clue Types
Exact Facts
True pieces of information stated directly by the author.
"They can change their skin color in 20 seconds."
Specific Examples
A real-world instance or story showing how something works.
"For instance, panther chameleons turn bright red to scare foes."
Numbers & Details
Measurements, counts, or body parts that provide hard proof.
"Their eyes can look in two different directions at once."
Golden Detective Rule: Text evidence comes directly from the author's words, not from our imagination!
Case File: Spotting the Best Clue
Guided Practice
Topic Sentence to Support:
"Chameleons have amazing superpowers that protect them from danger."
Reading Passage
Chameleons live in warm forests and deserts. They have specialized feet with fused toes that grip tree branches tightly. When a predator approaches, a chameleon can blend into leafy branches by shifting its skin colors. It also swivels its eyes separately to scan for hungry snakes.
Strong Evidence #1:
"A chameleon can blend into leafy branches by shifting its skin colors."
Strong Evidence #2:
"It swivels its eyes separately to scan for hungry snakes."
Notice: Both clues directly explain how the animal stays safe from danger!
Detective Warning: The Trap Fact!
Common Mistake
Just because a sentence is in the text does NOT mean it proves your topic sentence!
The Trap Fact
"Chameleons live in warm forests and deserts."
Is it true? Yes! No! Where an animal lives does not prove it has protective powers.
The Winning Evidence
"It swivels its eyes separately to scan for hungry snakes."
Is it true? Yes! Yes! Watching two directions at once spots predators before they attack.
Detective Test: Always ask yourself: "Does this clue actually prove my topic sentence?"

Lesson 1 • Hunting for Text Evidence
NAME:
DATE:
Detective Rule: Your topic sentence makes a claim. Text evidence is proof (facts, numbers, or actions) taken straight from the text that proves the claim is true!
Part 1: Warm-Up Case File Read carefully • Notice the underlined details
Topic Sentence (The Claim):
"The mimic octopus uses incredible tricks to escape predators."
The mimic octopus lives in warm ocean waters near Indonesia. Unlike other sea creatures, this smart animal can change its shape and movement to look like dangerous sea animals. When a hungry predator swims near, it tucks six of its arms together to swim like a venomous banded sea snake. It can also spread its arms wide to pretend to be a spiky lionfish. In addition, the octopus can change its skin color in a split second.
Check the Evidence: Which detail proves the topic sentence?
Check the ONE best clue that proves the octopus uses tricks to escape:
The mimic octopus lives in warm ocean waters near Indonesia.
It tucks six arms together to look and swim like a venomous banded sea snake.
Many different sea animals live in the ocean.
Part 2: Clue Extraction Find one MORE clue from the octopus passage above that proves it can escape danger.
Write the exact sentence or fact from the passage:
Why does this clue prove the octopus uses tricks to escape?

Pick either Case A or Case B . Read the passage and topic sentence, then record two pieces of strong text evidence.
CASE A
I choose Case A
Honeybee Teamwork
Topic Sentence:
"Honeybees work together in amazing ways to keep their hive alive."
Honeybees live inside large colonies with up to 60,000 bees. Every bee has a special job. Scout bees fly miles away to find flower nectar and perform a special "waggle dance" to show other bees the exact direction. Inside the hive, worker bees fan their wings over honeycombs to keep the hive cool. Other worker bees guard the hive entrance to block robber wasps.
CASE B
I choose Case B
The Saguaro Desert Oasis
Topic Sentence:
"The giant saguaro cactus is built to survive harsh desert droughts."
The saguaro cactus grows in the hot Sonoran Desert. Its root system spreads out like a wide underground web just 4 inches below the soil to soak up quick rainwater. The cactus skin has accordion-like pleats that stretch to store up to 200 gallons of water during a storm. A thick, waxy outer coating seals moisture inside so the sun cannot dry it out.

EVIDENCE SENTENCE FRAMES
Framing The Proof
How to use kid-friendly sentence starters so your evidence sounds smooth, smart, and convincing!
Today's Goal: Stop "dropping" clues randomly and start building strong Evidence Bridges.
Don't Just Drop the Clue!
Writing Secret
The "Clue Drop" Mistake
A clue drop happens when a writer sticks a fact into a paragraph with zero introduction:
"Chameleons have superpowers. Their eyes swivel in two directions. That is cool."
Problem: The reader has no idea where this fact came from!
The Framed Evidence
Great detectives introduce their clues by telling the reader who said it:
"Chameleons have superpowers. According to the text, their eyes swivel in two directions."
Success: The reader knows this is verified proof from the text!
Always give credit to the author or article before stating the fact.
4 Power Sentence Starters
Detective Toolkit
1
"According to the text..."
Great for sharing a big scientific fact or number straight from the author.
"According to the text, honeybees can fly miles to find sweet nectar."
2
"The author explains that..."
Perfect when you are summarizing how something works or why it happens.
"The author explains that worker bees fan their wings to cool the hive."
3
"In the passage, it states..."
Best when you want to highlight a surprising or powerful direct quote.
"In the passage, it states that saguaros hold 200 gallons of rain."
4
"For example, the text says..."
Ideal when you want to show a specific example that proves your point.
"For example, the text says guard bees block robber wasps."
Notice the comma: Starter , [Your Evidence Fact]
The 3-Part Evidence Bridge
Formula
Once you have your topic sentence, use these three steps to build the body:
Part A
Sentence Starter
Tell your reader where the information came from.
"According to the text,"
Part B
The Text Fact
Provide the exact evidence you hunted down in the reading.

Roller Coaster Forces
Topic Sentence:
"Roller coasters rely on clever forces of gravity and energy to thrill riders safely."
A motor pulls roller coaster cars up the very first hill to build stored potential energy. As cars plummet down, gravity transforms that stored energy into kinetic motion reaching 70 miles per hour. Steel wheel clamps lock under the tubular tracks so cars cannot lift off during steep corkscrews, and magnetic brakes smoothly stop the train.

3 Major Stumbling Blocks & Teacher Coaching Cues
Targeted Interventions
The "Trap Fact" (True But Irrelevant) Most Common
What happens: Students copy any interesting sentence from the text even if it doesn't support the specific topic claim.
Coaching Script: "Your fact is true, but does it prove [topic claim] ? If an audience doubted your claim, would this clue convince them?"
The "Clue Drop" (Missing Sentence Starter) Framing Error
What happens: Students paste a quote into the paragraph with zero introductory context or attribution.
Coaching Script: "Give credit to your source! Start your sentence with: 'According to the text,' or 'The author states that...' "
The "Quote & Run" (Missing Explanation) Reasoning Gap
What happens: Students state their evidence but never explain why it matters to the topic sentence.
Coaching Script: "Don't let the reader guess your thinking! Add your detective connector: 'This shows that...' to seal the proof."
Differentiation & Scaffolding Pathways
For Striving Writers (Support):
Pre-highlight the two strongest facts in their chosen passage.
Provide physical sentence starter strips for hands-on drafting.
Have students orally explain "This shows that..." prior to writing.
For Advanced Writers (Extension):
Challenge students to paraphrase evidence instead of direct quotation.
Introduce compound transitions like "Furthermore," or "Consequently."
Have students craft an original concluding insight rather than simple restatement.

Writing Prompt: What makes the axolotl one of nature's most incredible animals?
Read the text below. Then plan and draft your complete paragraph. You must write your own topic sentence , cite two pieces of text evidence with explanations, and finish with a concluding sentence .
Reading Passage: The Astonishing Axolotl
Informational Text
The axolotl (pronounced AK-suh-lah-tuhl) is a rare amphibian native to ancient lake canals in Mexico. Unlike typical salamanders that transform to walk on land as adults, the axolotl stays underwater its entire life and breathes through feathery pink gills that fan out like a crown around its head.
What astounds scientists most is the axolotl's power of extreme regeneration. If an axolotl loses a leg, it can regrow a brand-new, fully functioning limb within weeks without leaving any scar tissue. Even more remarkably, this creature can regenerate damaged parts of its heart, spine, and brain. Today, medical researchers study axolotls closely, hoping to unlock secrets to heal human injuries.

Writing Prompt: What makes the Venus flytrap such an unusual and deadly plant hunter?
Read the text below. Then plan and draft your complete paragraph. You must write your own topic sentence , cite two pieces of text evidence with explanations, and finish with a concluding sentence .
Reading Passage: The Carnivorous Venus Flytrap
Informational Text
Unlike ordinary green plants that absorb all their nourishment from soil, the Venus flytrap thrives in nutrient-poor bogs in North and South Carolina. Because the soggy wetland soil lacks nitrogen, this fascinating plant evolved into a meat-eater that captures live insects and spiders to survive.
The plant's jaw-like leaves secrete sweet-smelling nectar that lures bugs onto reddish inner lobes. Inside each lobe are sensitive trigger hairs. To avoid closing accidentally on falling raindrops, the trap only snaps shut if a bug touches two hairs within 20 seconds. Once triggered, the fringed leaf teeth snap closed in just one-tenth of a second, trapping the prey before digestive acids dissolve it for food.
