Comprehension: Understanding and Responding to Texts

A Grade 9 lesson on bringing relevant knowledge to a new text

Before reading, your mind already contains experiences, information, and ideas that may help you make sense of a text. C2.1 focuses on activating useful prior knowledge before reading. “Activate” means deliberately bringing relevant knowledge to mind. “Useful” matters: the goal is not to list everything you know, but to select what may help with this particular text. In this lesson, you will practise making a brief connection before reading, keeping guesses separate from known information, and adjusting your thinking when the text gives you new details.

What you will learn

Explain what it means to activate useful prior knowledge before reading.
Choose a small amount of relevant knowledge to bring to an unfamiliar text.
Separate what you already know from what you can only predict.
Use details from a title or other preview information to guide your thinking without treating a guess as a fact.

1. Start with an original text and a small preview

The passage below is an invented example for this lesson. First, read only its title. Pause before reading the passage and ask: What do I already know that might help me understand a text with this title? You might draw on something you have seen, learned, or experienced. The knowledge should connect to the title, not merely be something you find interesting.

Invented passage: “The Quiet Corner. On Monday, a class moved two chairs and a small table beside the library windows. A paper sign invited students to use the space for quiet reading or a short break. By Wednesday, the sign had a folded-paper cover because the window light made its words hard to see. One student suggested moving the table; another preferred adding a darker sign. The class left both ideas on a note for the next meeting.”

Before reading, a reader might know that strong light can make some writing difficult to see. That knowledge could help with the detail about the sign. A reader might also know that people can have different ideas about how to solve a problem. That could help make sense of the two suggestions. These are relevant starting points, not proof of what the class members felt or why the space was created.

You do not need to predict the whole passage. One or two useful connections are enough. A short note such as “Bright light can make a sign harder to read” gives you something to bring to the text while leaving room for its actual details.

Use the title or other available preview information to choose relevant knowledge.
Keep prior knowledge brief and connected to the text.
A connection can help you get ready to read, but it does not tell you what the passage will say.

2. Model: distinguish what you know from what you expect

Here is a model of the before-reading move using the title “The Quiet Corner.” The reader thinks: “I have seen people use a quiet place to read or take a short break. A shared space may need signs so people know how it can be used. I wonder whether students will agree about how to arrange it.” The first two statements draw on prior knowledge. The last is a question or expectation, not a known fact about this passage.

After reading the invented passage, the reader can check the connection. The words “quiet reading or a short break” support the idea that the space has two possible uses. The text says that one student suggested moving the table and another preferred a darker sign. It does not say that the students argued, that everyone used the space, or that the class chose either solution.

This careful separation keeps a useful connection from turning into an unsupported claim. An observation is a detail stated in the passage. An inference is a reasonable idea that a reader develops from details. For example, the note for the next meeting may suggest that the class has not made a final choice. That is a reasonable inference because both ideas were left for discussion, but it remains an inference rather than a stated fact.

Different readers may bring different relevant knowledge. One might focus on how light affects visibility; another might think about how a shared space can serve more than one purpose. Both can be useful if the reader stays open to what the passage actually says. Before reading, the aim is not to arrive at one correct prediction. It is to prepare a relevant starting point.

Label a remembered fact, an expectation, or a question honestly.
After reading, check whether the passage supports or changes your starting idea.
More than one relevant connection may help different readers.

3. Guided practice: choose the connection that fits

Imagine that the next invented passage is titled “A Borrowed Umbrella.” Before reading, you think of three things: you know that rain can make a walk uncomfortable; you once forgot a notebook at home; and you wonder whether the umbrella will be returned. Which ideas are useful? The first connects to an umbrella and possible weather. The question about returning it may become relevant, but it is an expectation rather than prior knowledge. The forgotten notebook is a real memory, but by itself it has no clear link to the title.

A useful pre-reading note could be: “Rain can make it harder to travel comfortably. I wonder who borrowed the umbrella and whether it comes back.” This note uses a relevant piece of knowledge and marks the questions as questions. It does not claim to know what happens in the passage.

Now consider a digital preview. Suppose a teacher shares the title and a small image of an umbrella beside a doorway. You can use those visible details to prepare, but you should not invent information about who made the image or what happened outside the frame. A simple note could say: “The image shows an umbrella near a doorway. I know umbrellas are used in wet weather. I wonder why it was left there.” The visible image is an observation; your remembered information and question are different kinds of thinking.

A brief note can be made privately or shared with a partner. If you share it, say which part comes from your own knowledge and which part is a question. A partner may bring a different useful connection. Listen for whether that connection relates to the title or preview, rather than deciding that one person’s experience must apply to everyone.

Select knowledge because it connects to the preview, not just because it is memorable.
Treat a digital image or title as limited evidence: use what is actually visible or stated.
Listening to another reader can offer a new connection without requiring you to adopt it.

4. Try it, get feedback, and adjust

Choose an unfamiliar short text you are allowed to read, or ask someone to give you only its title and one preview detail. Before reading, write two or three brief lines: one relevant thing you already know, one question or expectation, and, if helpful, what in the preview led you to think of it. Do not write a full summary before you have read the text.

Then read the text and revisit your note. Which prior knowledge helped you understand a detail? Which expectation was not confirmed? Did something in the text change what you thought might matter? The purpose is not to prove your prediction right. It is to notice how your starting knowledge met the information in the text.

For evidence-based feedback, ask a partner to point to the words in your note that show a connection to the preview. They can ask, “Which part do you already know, and which part are you wondering about?” You can revise an unclear note by naming the source of your idea more precisely. For instance, change “The room will be peaceful” to “I associate quiet reading spaces with fewer distractions; I wonder whether this one works that way.” This revision keeps your idea while making clear that it is a personal expectation, not a fact supplied by the title.

If the text is shared digitally, use only the information you can actually see, such as its title or an included image. Do not treat an unverified caption or your guess about an image as established information. The same habit supports thoughtful reading in print and online: bring relevant knowledge, identify what is a guess, and remain ready to respond to the text itself.

Write a short pre-reading note, then compare it with the text after reading.
Use feedback to make the connection clearer, not to replace your own voice.
Keep observations, prior knowledge, and expectations distinct.

Worked example

Model a relevant connection

Before reading the invented passage “The Quiet Corner,” make one useful connection from prior knowledge and one question. Then identify a passage detail that could help you check your thinking.

Choose relevant knowledge
The title suggests a quiet shared space. A reader may already know that people use quiet places for reading or taking a short break. This connection is relevant because it relates directly to the title.
Mark the question as uncertain
The reader can wonder how the space will be arranged, but cannot know the answer from the title alone. Keeping it as a question prevents an expectation from becoming a claimed fact.
Check against the passage
The passage mentions “quiet reading or a short break,” which supports the connection. Its two suggestions about the table and sign provide details to consider, but do not show that one suggestion was chosen.

Answer: Useful connection: quiet places may be used for reading or a break. Question: How will the class decide what to change? A detail to check is that the class leaves both ideas on a note for the next meeting.

Check: The response labels prior knowledge and a question separately, then uses actual passage details rather than assuming an outcome.

Worked example

Sort three possible connections

Before reading an invented text titled “A Borrowed Umbrella,” sort these thoughts: rain can make a walk uncomfortable; you once forgot a notebook; you wonder whether the umbrella will be returned.

Find what connects
The thought about rain relates to an umbrella, so it may be useful prior knowledge. The notebook memory is real, but the title gives no clear link between that memory and the text.
Separate knowledge from a question
Wondering whether the umbrella will be returned is a question, not prior knowledge. It can guide attention, but it should not be treated as a prediction that must come true.
Make a concise note
Combining the relevant knowledge with the question prepares the reader without claiming to know the story’s events.

Answer: “Rain can make a walk uncomfortable. I wonder whether the borrowed umbrella will be returned.” The notebook memory can be left out unless the text later gives it a clear connection.

Check: The note includes a relevant connection and clearly marks the uncertain idea as a question.

Worked example

Use a digital preview carefully

A digital preview shows the title “A Borrowed Umbrella” and an umbrella beside a doorway. Write a pre-reading note using only the visible information and relevant prior knowledge.

Name the visible detail
The preview shows an umbrella beside a doorway. This is an observation about the image, not evidence about who owns the umbrella or why it is there.
Add relevant prior knowledge
A reader may know that umbrellas are used in wet weather. This knowledge connects to the object shown and may be useful when reading.
Keep the inference open
The reader can ask why the umbrella is by the doorway, but should not claim that someone forgot it. The image alone does not establish that explanation.

Answer: “The image shows an umbrella beside a doorway. I know umbrellas are used in wet weather. I wonder why it is there.”

Check: The note separates an image observation, relevant prior knowledge, and an unanswered question.

Common mistakes and how to avoid them

Listing every related memory, even when it does not connect to the text preview.

Correction: Choose one or two pieces of knowledge that have a clear link to the title or preview.

Treating a question or prediction as something the text has already established.

Correction: Mark it as a question or expectation, then check it against the text after reading.

Assuming an image or title reveals details it does not show.

Correction: Name what is actually visible or stated, and keep explanations as possibilities until the text supports them.

Thinking that a useful connection must match every reader’s experience.

Correction: Use your knowledge as a starting point, stay open to other readers’ relevant connections, and let the text provide its own details.

Lesson summary

Activate prior knowledge before reading by deliberately recalling information or experience that connects to the title or preview.
Keep remembered knowledge separate from questions and expectations.
After reading, check your starting ideas against the text and adjust them when needed.
For digital previews, use only details actually shown or stated.

Check your understanding

Question 1

A title is “The School Garden.” Which is the clearest example of relevant prior knowledge?

You know that plants need water to grow.
You remember the colour of a shirt you wore yesterday.
You are certain the passage will describe a prize.
correctIndex ha???

Show answer and explanation

You know that plants need water to grow.

Knowledge about plants connects directly to the title. The shirt memory does not have a clear link, and the prize is an unsupported expectation.

Question 2

You see a preview image of a closed box. Which statement is an observation?

Someone has hidden a gift.
The image shows a closed box.
The box contains books.
correctIndex ha???

Show answer and explanation

The image shows a closed box.

The closed box is visible. Its purpose and contents are not established by that detail.

Question 3

Before reading, you write, “I wonder whether the character will return the umbrella.” What kind of thinking is this?

A fact stated by the text.
A question or expectation.
A detail visible in an image.
correctIndex ha???

Show answer and explanation

A question or expectation.

The sentence openly asks about a possible event. It is not a fact until the text provides information about it.

Key terms

Prior knowledge: Information, experience, or ideas you already have before reading a particular text.
Activate: Deliberately bring something to mind for a purpose.
Observation: A detail directly stated in a text or visibly shown in a preview.
Inference: A reasonable idea a reader develops from details, while recognizing that it is not stated directly.
