Activating Prior Knowledge
Activating Prior Knowledge means thinking about what you already know before you read.
Before we open a book, our brain can get ready. We can remember things we have seen, done, heard, or learned before. This helps us understand the new text better.
When we activate prior knowledge, we ask ourselves:
- What do I already know about this topic?
- What have I seen or done that matches this?
- What words do I already know about this topic?
This is like turning on a light in your brain. The light helps you see the new reading more clearly.
Why is this important?
- It helps us get ready to read.
- It helps us understand the story or book.
- It helps us make good guesses about what we will read.
- It helps us remember new ideas.
How do we activate prior knowledge?
- Look at the title.
- Look at the pictures.
- Think about what the topic reminds you of.
- Say what you already know.
- Then begin reading.
You can use simple sentence starters like these:
- I already know...
- This reminds me of...
- I remember...
- I think this book will be about...
Important: Prior knowledge can come from your life or from things you learned before.
- Your life: going to the park, seeing rain, having a pet
- Things you learned: butterflies come from caterpillars, plants need water, winter is cold
When we use prior knowledge, we do not tell a random story. We think about ideas that match the topic.
For example, if the book is about apples, it helps to think about eating apples, seeing apple trees, or learning that apples are fruit. It does not help to talk about a beach trip if the beach is not connected to apples.
Worked Example 1
Text title: My Puppy
Before reading, we stop and think: What do I already know about puppies?
- Puppies are маленькие dogs. Wait—let's say it in simple English: puppies are baby dogs.
- They can bark.
- They like to play.
- They need food and water.
Good prior knowledge thought: “I already know puppies are baby dogs, so this book may tell about how a puppy looks or plays.”
This helps the reader get ready for the book.
Worked Example 2
Text title: Rainy Day
Look at the title and picture. Maybe you see clouds, boots, and an umbrella.
Now think:
- I have seen rain.
- Rain falls from clouds.
- People wear boots in puddles.
- An umbrella can help keep us dry.
Good prior knowledge thought: “This reminds me of rainy days. I already know people use umbrellas in the rain.”
Now the reader is ready to understand the text better.
Worked Example 3
Text title: How a Seed Grows
This book is not only about something you have done. It can also be about something you learned.
Before reading, think:
- Seeds go in the dirt.
- Plants need water.
- Plants need sunlight.
- A seed can grow into a plant.
Good prior knowledge thought: “I already know seeds need water, so this book may teach me more about how plants grow.”
This prior knowledge helps the reader understand new facts in the book.
Worked Example 4
Text title: At the Fire Station
Before reading, ask: What do I know about a fire station?
- Firefighters work there.
- They help people.
- They ride in fire trucks.
- They may wear helmets.
Good prior knowledge thought: “I remember seeing a fire truck. I already know firefighters help put out fires.”
This helps the reader understand the topic before reading begins.
Let’s learn the difference between helpful and not helpful thinking.
Topic: The Beach
- Helpful prior knowledge: sand, waves, water, shells, sunscreen
- Not helpful prior knowledge: my math worksheet, my winter coat, a trip to the dentist
Helpful prior knowledge matches the topic.
What if you do not know much about the topic?
That is okay. You can still activate prior knowledge by looking carefully at the title and pictures.
You might say:
- “I see a farm.”
- “I know cows live on farms.”
- “I think this book will be about farm animals.”
Even a small idea can help your brain get ready to read.
Try this thinking plan every time you read:
- Stop before reading.
- Look at the title.
- Look at the pictures.
- Think: “What do I already know?”
- Say one or two ideas.
- Start reading.
Practice Questions
Here are some titles. Think about what prior knowledge you could use.
- My Snow Day → I already know snow is cold. People wear coats and mittens.
- The Big Red Bus → I already know buses carry people. School buses take children to school.
- Birds in the Nest → I already know birds lay eggs. Baby birds can live in nests.
Remember: Activating prior knowledge happens before you read. It helps you understand what you read during reading.
Good readers do this all the time. They get their brains ready by thinking about what they already know.
Summary
Activating prior knowledge means thinking about what you already know before reading a text. You can use your own life, things you have seen, and things you have learned before.
To do this, look at the title and pictures, then ask, “What do I already know?” Think of ideas that match the topic. This will help you understand the book or story better.
