Explaining Events, Ideas & Concepts in Informational Text |...

Section 1

Why Does Explaining What You Read Matter?

Every day, people read all kinds of nonfiction writing. A doctor reads about how a new medicine works. A builder reads the steps for putting up a roof. A student reads about why volcanoes erupt. In every case, the reader needs to explain what the text is telling them — not just repeat it word-for-word, but really understand it and put it in their own words.

People have been writing informational texts for thousands of years! Here is a short timeline showing how nonfiction writing has changed over time.

~3000 BCE

Ancient Egyptians wrote instructions on papyrus scrolls. They explained steps for building pyramids and preparing food.

~350 BCE

The Greek thinker Aristotle wrote books about animals and nature. He explained why things happen, not just what happens.

1440s

The printing press was invented. Now nonfiction books could be shared with lots of people, and students needed to learn how to understand them.

1900s

Schools started teaching reading comprehension as a skill. Students practiced explaining what they read in science, history, and more.

Today

You read informational text on websites, in textbooks, and in articles. Being able to explain events, steps, ideas, and concepts is one of the most important skills you can learn!

So here's the big question this lesson helps you answer: When you read a passage about history, science, or how something works, how do you figure out what it means and explain it clearly?

Section 2

Four Things You Can Be Asked to Explain

When your teacher asks you to "explain" what you read in an informational text, they usually want you to talk about one of four things. Let's learn about each one.

Events

Events are things that happened. In a history book, an event might be a battle, a discovery, or a law being passed. You explain an event by saying what happened, when it happened, and why it was important.

Procedures

A procedure is a set of steps that tells you how to do something. A recipe is a procedure. So are the directions for a science experiment. You explain a procedure by describing the steps in order.

Ideas

An idea is a thought or opinion the author shares. For example, an author might have the idea that recycling helps the Earth. You explain an idea by saying what the author thinks and what reasons they give.

Concepts

A concept is a big topic or principle. "Gravity" is a concept. So is "democracy." You explain a concept by describing what it means and giving examples that help someone else understand it.

✦ Key Takeaway

Think of reading an informational text like being a detective. The text is full of clues — facts, steps, reasons, and examples. Your job is to gather those clues and then explain to someone else what you found. It's like telling a friend about a movie, but instead of a story, you're explaining something real!

Section 3

How Events, Procedures, Ideas & Concepts Connect

The diagram below shows how these four things relate to each other. Events and procedures often come with a time order — things happen first, next, then, and finally. Ideas and concepts are more about understanding — you have to think about what something means and why it matters.

Notice in the diagram that events and procedures are at the top and use time order — they are about things happening in a sequence. Meanwhile, ideas and concepts are at the bottom and are about understanding — they ask you to think deeply about meaning. All four connect back to the informational text in the center.

Section 4

How to Explain What You Read: A Step-by-Step Method

Good readers don't just read once and say "I'm done." They use a method — a set of steps — to make sure they really understand. Here is a method you can use every time you read an informational text.

Let's look at each step a little more closely. In Step 1, you read the whole passage carefully. Don't rush! In Step 2, ask yourself: "Is this about something that happened, steps to follow, what the author thinks, or a big topic I need to understand?" This tells you what kind of explanation you need to write. In Step 3, you hunt for key details — signal words like "because," "first," "as a result," or "for example" will point you to important information. In Step 4, you take all those details and write your explanation in your own words. Finally, in Step 5, you go back and check. Did you miss anything important? Does your explanation make sense?

✦ Key Takeaway

Using these five steps is like following a treasure map. The passage is the map, the key details are the landmarks, and your explanation is the treasure you find at the end. If you skip a step, you might miss the treasure!

Section 5

Three Types of Informational Text

The Common Core standard mentions three kinds of informational text: historical, scientific, and technical. Each kind is a little different. The table below shows what to expect in each type.

Type of Text	What It's About	What You'll Explain	Signal Words to Look For
Historical	Events from the past — wars, discoveries, famous people	Events and their causes; why something happened	dates, because, as a result, led to, after, before
Scientific	How nature works — animals, weather, space, the body	Concepts and ideas; how or why something works	for example, such as, this means, therefore, due to
Technical	How to do something — experiments, recipes, instructions	Procedures; the steps in the right order	first, next, then, finally, step 1, be sure to

When you know which type of text you are reading, it's easier to figure out what to explain. If you see dates and words like "because" and "as a result," you're probably reading a historical text and need to explain events. If you see words like "first," "next," and "then," you're probably reading a technical text and need to explain a procedure.

Worked Example: Explaining a Science Passage

Let's practice the five steps with a real passage. Read the passage below and then follow along as we explain the concept.

📝 Sample Passage — Science

The water cycle is the way water moves around Earth over and over again. First, the sun heats water in oceans, lakes, and rivers. This causes the water to evaporate, which means it turns into an invisible gas called water vapor. The water vapor rises into the sky and cools down. As it cools, it condenses, meaning it turns back into tiny water droplets. These droplets form clouds. When the clouds get heavy with water, the droplets fall back to Earth as rain or snow. This is called precipitation. The water flows into rivers and oceans, and the cycle starts all over again.

Worked Example — Explaining the Water Cycle

Step 1 — Read CarefullyWe read the whole passage slowly. It talks about water moving around Earth.

Step 2 — Identify What to ExplainIs this about an event, a procedure, an idea, or a concept? The passage explains a concept — the water cycle. It tells us what the water cycle is and how it works.

Step 3 — Find Key DetailsHere are the key details we found: • The sun heats water → water evaporates (turns into gas) • Water vapor rises and cools → it condenses (turns into droplets) → clouds form • Clouds get heavy → water falls as precipitation (rain or snow) • Water flows back to oceans and rivers → the cycle repeats

Step 4 — Put It in Your Own WordsHere is our explanation: "The water cycle is how water keeps moving around Earth. The sun warms up water and turns it into a gas that floats up into the sky. When it cools off, it becomes tiny drops that make clouds. When clouds have too much water, it falls back down as rain or snow. Then the water goes back to rivers and oceans, and the whole thing happens again."

Step 5 — Check Your ExplanationWe reread the passage. Did we include the main parts? ✅ Evaporation. ✅ Condensation. ✅ Precipitation. ✅ The cycle repeating. Our explanation covers all the important parts. Great job!

Section 7

Helpful Strategies & Common Mistakes

Now that you know the method, let's look at some tips that will make your explanations even better — and some mistakes to avoid.

✅ Good Strategy	❌ Common Mistake	Why It Matters
Use your own words	Copying sentences from the text	Using your own words shows that you truly understand the information
Include the most important details	Trying to include every single detail	A good explanation focuses on the main idea, not every tiny fact
Use signal words (because, so, this means)	Listing facts without connecting them	Signal words show how facts are related, not just what they are
Explain cause and effect	Only saying what happened, not why	Saying why something happened makes your explanation much stronger
Reread to check your work	Writing once and not looking back	Checking helps you catch missing details or mistakes

✦ Key Takeaway

Think of it this way: if you tried to explain to a friend how to make a peanut butter sandwich but you only said "Put peanut butter on bread," they'd be confused! A good explanation includes the important steps or reasons so the other person can understand, even if they've never read the passage themselves.

Going Deeper: Connecting to Bigger Skills

Explaining events, procedures, ideas, and concepts is a skill you'll use all the way through school — and in life! As you get older, the texts will get harder, but the same basic thinking applies. Here's how this skill grows with you.

What You Learn Now (4th Grade)	What Comes Next (5th–6th Grade)
Explain what the text says happened	Explain how two events in a text are connected (cause and effect chains)
Explain the steps in a procedure	Compare two different procedures and explain which one works better
Explain what an idea means	Analyze whether the author gives enough evidence to support the idea
Explain a concept using details from the text	Explain a concept using details from multiple texts and compare them

Right now, you're building a strong foundation. Every time you practice explaining what you read, you're training your brain to think clearly and carefully. That's a skill that will help you in science class, history class, and even when you're reading instructions for a new video game!

Section 9

Practice Problems

Now it's your turn! Try these five problems. For each one, think carefully before you look at the answer.

PROBLEM 1 — CONCEPTUAL

What is the difference between an event and a procedure in an informational text?

PROBLEM 2 — IDENTIFICATION

Read this short passage: "In 1969, astronaut Neil Armstrong became the first person to walk on the moon. This event was watched by millions of people on TV. It showed that humans could travel beyond Earth." Is this passage mostly about an event, a procedure, an idea, or a concept?

PROBLEM 3 — INTERMEDIATE

Read this passage and then explain the concept of camouflage in your own words: "Many animals use camouflage to stay safe. Camouflage means an animal's color or pattern helps it blend in with its surroundings. For example, a green frog sitting on a green leaf is hard for a bird to see. A white rabbit in the snow is almost invisible. Camouflage helps animals hide from predators that want to eat them."

PROBLEM 4 — APPLIED

Read this passage about how to make a bird feeder: "To make a simple bird feeder, you will need a pine cone, peanut butter, and birdseed. First, tie a string around the top of the pine cone so you can hang it later. Next, spread peanut butter all over the pine cone with a butter knife. Then, roll the sticky pine cone in a plate of birdseed until it is covered. Finally, hang your bird feeder from a tree branch outside." Explain the procedure described in this passage. Make sure to include the steps in the correct order.

PROBLEM 5 — CHALLENGE

Read the two short passages below. One is historical and one is scientific. For each one, identify which type it is, and then write a one- or two-sentence explanation of the main event or concept. Passage A: "In 1903, Orville and Wilbur Wright flew the first powered airplane at Kitty Hawk, North Carolina. Their flight lasted only 12 seconds, but it changed the world forever because it proved that humans could fly." Passage B: "Magnets have two poles: a north pole and a south pole. When you put two magnets near each other, opposite poles attract (pull toward each other) and same poles repel (push away). This is why the north end of one magnet sticks to the south end of another."

Summary

Lesson Summary

In this lesson, you learned how to explain events, procedures, ideas, and concepts when you read informational text. An event is something that happened, and you explain it by telling what happened and why it mattered. A procedure is a set of steps, and you explain it by describing those steps in order. An idea is a thought the author shares, and you explain it by saying what the author thinks and what reasons they give. A concept is a big topic or principle, and you explain it by describing what it means and giving examples.

You also learned a five-step method: read carefully, identify what to explain, find key details, put it in your own words, and check your work. You practiced recognizing signal words that tell you whether a text is historical, scientific, or technical. Remember — a great explanation doesn't copy the text. It uses your own words and includes the most important details so that anyone who reads your explanation can understand the passage, even if they never read it themselves!
