Unit 1 — Becoming an Independent Reader

Welcome to Grade 4!

You have learned many reading skills during the past several years.

Now you will begin using those skills more independently.

Reading is no longer only about learning how to read.

It is about using reading to discover new ideas, solve problems, answer questions, and understand the world.


Reading with a Purpose

Every time you read, ask yourself:

Knowing your purpose helps you pay attention to the most important information.

Different purposes include:


Identifying the Main Idea

Every passage has one central idea.

This is called the main idea.

The other details support or explain that main idea.

For example:

Main idea:

"Bees are important pollinators."

Supporting details might explain:

Strong readers can separate important ideas from minor details.


Finding Supporting Evidence

Authors support their ideas with evidence.

Evidence may include:

When answering questions, explain which evidence supports your answer.

Using evidence makes your thinking stronger.


Making Inferences

Authors do not always tell readers everything directly.

Sometimes readers must combine clues from the text with what they already know.

This is called making an inference.

For example:

"The sidewalk was wet and everyone carried umbrellas."

The author never says it rained, but most readers can reasonably infer that it did.

Good readers support their inferences with evidence.


Expanding Vocabulary

Grade 4 introduces many new words.

When you encounter an unfamiliar word:

Learning new words improves both reading and writing.


Asking Better Questions

Independent readers ask questions while reading.

Examples include:

Questions keep your mind actively involved.


Activity

Choose a nonfiction article or chapter.

As you read:

Discuss your answers with a classmate, teacher, or family member.


Practice

Answer these questions.

What is the main idea?

What kinds of information count as supporting evidence?

What is an inference?

Why should readers ask questions while reading?

How can context help you understand unfamiliar words?


Review

Today you learned:

Independent readers think actively before, during, and after reading.


Looking Ahead

Next we will learn how authors organize information, develop themes, present arguments, and communicate ideas through different types of writing.
