Text Detectives Lesson Plan Text Detectives: Structure!
Instructional Facilitation Guide
40 Minutes Grade 5 • Tier 1
MISSION OBJECTIVE
Students will identify and describe five non-fiction text structures and explain how these blueprints aid comprehension using evidence from the text and signal words.
THE "WHY"
Recognizing organization allows students to anticipate information, organize thoughts, and improve recall—essential skills for mastering complex informational texts across all subjects.
Pre-Mission Preparation (15 min)
Review Lesson Plan & Slide Deck.
Print Warm Up: Structure Match-Up (1/student).
Print Text Structure Worksheet (1/student).
Print Text Structure Exit Ticket (1/student).
Prepare projector for Slide Deck .
MISSION TIMELINE
5 MIN
Warm-Up: Structure Match-Up
Goal: Activate prior knowledge and curiosity.
Distribute the Match-Up sheet.
Students scan short paragraphs for "clue words" to match them to structures.
Briefly review: "What words tipped you off?" (Don't reveal everything yet).
10 MIN
Instruction: The Detective Toolkit
Goal: Explicitly teach the 5 structures.
Use Slide Deck (Slides 1-5).
Introduce the "Blueprint" analogy: Buildings have frames; texts have structures.
Define the "Big Five": Description, Sequence, Compare/Contrast, Cause/Effect, Problem/Solution.
15 MIN
Guided Exploration: Analyzing Evidence
Goal: Practice identifying structures in context.
Continue Slide Deck (Slides 6-15).
For each structure, present the example paragraph.
Guided Questioning: "What signal words do you see?", "If we drew this as a map, what would it look like?" (Venn diagram, timeline, etc.)
8 MIN
Independent Practice: Field Report
Goal: Student mastery check.
Distribute Text Structure Worksheet .
Students work independently to classify five new passages.
Circulate to check for students who confuse Problem/Solution with Cause/Effect (Common Misconception).
2 MIN
Cool Down: Exit Ticket
Distribute and collect the Exit Ticket .
Review responses to identify students needing small-group re-teaching.

Text Detectives:
Structure!
Uncovering the Hidden Blueprints of Non-Fiction
NOTES: Welcome students. Introduce the topic: becoming 'Text Detectives' to uncover how non-fiction books are built.
What is Text Structure?
It's like the blueprint or framework an author uses to organize information.
Think of it as the way the ideas are put together to help you understand the message!
The Building Analogy
Strong Foundations
Buildings need a plan to stand tall and make sense.
Organized Plans
Authors use structures to build a clear and understandable message.
Why do we need clues?
Understand
It helps you grasp complex ideas more quickly.
Remember
Organized info sticks in your brain better!
Expertise
Makes you a smarter reader and a better writer!

Problem & Solution
1. Description
Case Profile
The Purpose
The author describes a topic by listing its characteristics, features, and examples.
Signal Words
For instance Specifically Looks like For example
Evidence Exhibit A
The Amazon Rainforest is an incredible place. It is home to an amazing variety of plants and animals, including colorful toucans, agile monkeys, and jaguars. The trees are tall and form a dense canopy, blocking much of the sunlight from reaching the forest floor. The air is warm and humid, creating a perfect environment for lush vegetation. For instance, many unique orchids and giant water lilies thrive there.
2. Sequence
The Timeline
The Purpose
The author presents events, ideas, or steps in the order they happen.
Signal Words
First / Next Initially Before / After Finally
Evidence Exhibit B
First, gather your ingredients: two slices of bread, peanut butter, and jelly. Next, spread peanut butter on one slice. Then, spread jelly on the other slice. After that, put the slices together. Finally, enjoy!

Evidence Files
1. The Giant Panda
The giant panda is a fascinating creature known for its distinctive black and white fur. It primarily eats bamboo, spending up to 12 hours a day munching on the plant. Pandas have a round face, large dark patches around their eyes, and a thick, woolly coat.
2. How to Make a Paper Airplane
First, fold a piece of paper in half lengthwise. Next, fold the top two corners to meet the center crease. Then, fold the top edges to the center again. Finally, fold down the wings, and you're ready to fly!
3. Hurricanes vs. Tornadoes
Both hurricanes and tornadoes are powerful natural disasters. However, they form in very different ways. Hurricanes form over warm ocean waters, whereas tornadoes form over land during severe thunderstorms.
4. Pollution Effects
Because of industrial pollution, many lakes have become contaminated. As a result, fish are losing their habitats. Consequently, some species are declining in population.
5. The Playground Dilemma
Our playground has a significant problem: the swings are broken and unsafe. One solution is for the PTA to organize a fundraiser to raise money for new, safer equipment.

Passage 1: Butterfly Cycle
The butterfly's journey is a marvel. First, eggs are laid on a leaf. Next, a caterpillar hatches and eats. Then, it forms a chrysalis. After several weeks, it splits open and a butterfly emerges. Finally, it is ready to fly.

Passage 2: Rainforest vs. Desert
Both have unique ecosystems. However, they are different. Rainforests have high rainfall. In contrast, deserts have very little. Unlike a desert, a rainforest has a constant supply of water.

Evidence/Why:
Passage 3: The Ozone Layer
The ozone layer is a vital part of Earth's atmosphere. It is a protective shield that absorbs radiation. It is found in the stratosphere. Specifically, it is made of ozone molecules consisting of three oxygen atoms. It looks like a thin layer.

Evidence/Why:
Passage 4: Plastic Waste
Plastic pollution is a growing problem worldwide. One solution is for individuals to reduce single-use plastics. Another effective solution involves improving recycling programs so that less waste ends up in nature.
Structure:
Evidence/Why:
Passage 5: Volcanoes
When pressure from gases becomes too great, magma forces its way upwards. As a result, molten rock and ash are expelled. Consequently, this eruption can cause significant destruction and alter the landscape.

3 Final Analysis: Read the passage and identify the structure.
"Many students find it challenging to organize their notes effectively. One helpful strategy is to use graphic organizers, which provide a visual framework for structuring information. Another solution is to create outlines before writing, allowing students to map out their ideas logically."

Evidence: Identifies the 'problem' of pollution and offers two 'solutions' (reducing use, improving recycling).
Passage 5: Volcanoes
Structure: Cause & Effect
Evidence: Explains why eruptions happen (gases building up) and the result (destruction). Clues: As a result, Consequently.
