Text Structure Worksheet 2 | Reading Activity - Free Printable

Problem Analysis:

The task requires organizing information from two passages into appropriate graphic organizers. The passages provided are:

1. The Age of the Dinosaurs: Discusses the timeline and periods of dinosaur existence, including Triassic, Jurassic, and Cretaceous.
2. Vicious Predators: Compares the characteristics of two dinosaurs, Tyrannosaurus rex and Velociraptor.

The graphic organizers available are:
- Chronological: For events in a time sequence.
- Sequence: For step-by-step processes.
- Cause and Effect: For identifying causes and their effects.
- Problem and Solution: For identifying problems and solutions.
- Compare and Contrast: For comparing similarities and differences.

Solution Approach:

We will analyze each passage and determine which graphic organizer best fits the structure of the information.

#### Passage 1: The Age of the Dinosaurs

Content Summary:
- Discusses the timeline of dinosaur existence (250 million to 65 million years ago).
- Breaks down the era into three periods: Triassic, Jurassic, and Cretaceous.
- Provides specific time frames for each period:
- Triassic: 250–205 million years ago.
- Jurassic: 205–138 million years ago.
- Cretaceous: 138–65 million years ago.
- Describes changes on Earth during these periods, such as the formation and separation of continents.

Graphic Organizer Selection:
This passage is structured chronologically, detailing the sequence of events over time. Therefore, the Chronological graphic organizer is the most appropriate.

Organized Information:
- Time Line:
- Triassic Period: 250–205 million years ago.
- All continents united to form Pangaea.
- Jurassic Period: 205–138 million years ago.
- Continents began shifting apart.
- Cretaceous Period: 138–65 million years ago.
- Continents fully separated (except Australia and Antarctica).

#### Passage 2: Vicious Predators

Content Summary:
- Compares two predators: Tyrannosaurus rex and Velociraptor.
- Highlights physical characteristics and hunting abilities:
- Tyrannosaurus rex: Large size (20 feet tall, 7 tons), powerful jaws (3,000 lbs. of force).
- Velociraptor: Small size (3 feet tall, 35 pounds), fast speed (24 mph), retractable toe claw.
- Notes similarities: Both had eyes on the front of their heads for tracking prey.
- Mentions that scientists believe these two species never fought due to their different timelines.

Graphic Organizer Selection:
This passage compares two dinosaurs by highlighting their similarities and differences. Therefore, the Compare and Contrast graphic organizer is the most appropriate.

Organized Information:
- Alike:
- Both had eyes on the front of their heads for tracking prey.
- Both used their jaws to kill prey.
- Different:
- Tyrannosaurus rex:
- Large size (20 feet tall, 7 tons).
- Powerful jaws (3,000 lbs. of force).
- Existed earlier than Velociraptors.
- Velociraptor:
- Small size (3 feet tall, 35 pounds).
- Fast speed (24 mph).
- Had a retractable toe claw.
- Existed later than Tyrannosaurus rex.
