Words to know

prior knowledge
What you already know before you read, from your experiences, other texts and other subjects.
prediction
A thoughtful guess about what will happen or what a text will say, based on clues and what you know.
checking question
A question you pose to test whether your prediction is right, such as Will they reach shore before the storm?
monitoring
Keeping track of whether you understand as you read, and noticing when you don't.
fix-up strategy
A strategy you use when your understanding breaks down, such as rereading, reading ahead, visualizing or looking something up.
consulting references
Using a dictionary, glossary, diagram, encyclopedia or another reliable source to understand a word or idea.
cohesive tie
A word that links ideas across sentences, such as a pronoun (it, she, they) or a transition (then, however, by the time).
main clause
The part of a sentence that has a subject and a verb and could stand alone as a sentence.

Remember from Grade 6

In Grade 6 you used prior knowledge, made and revised predictions, and used fix-up strategies when you got stuck. You also found main clauses and cohesive ties.

In Grade 7 you'll do these things with more complex texts, and you'll do something new with predictions: pose questions that test them, so you know exactly what evidence to watch for.

Hook: What do you already know?

The story in this lesson is about a canoe trip and a thunderstorm. Before reading, jot down what you already know:

  • Personal experience: Have you been in a canoe? Been caught in a storm?
  • Other texts: Have you read stories or watched videos about wilderness trips?
  • Science: What do you know about lightning and thunder? (In science you may have learned that light travels much faster than sound, so you see lightning before you hear thunder.)
  • Geography and health: What do you know about Ontario's lakes and safety outdoors?

This is your prior knowledge. It will help you make predictions and understand what the characters do.

A red canoe pulled up on a rocky lakeshore in a pine forest while dark storm clouds gather over the far side of the lake.
What do you predict will happen on a canoe trip when clouds like these build? Your prior knowledge about storms and lakes helps you make predictions as you read. AI-generated image

After the Haze (a story written for this website), Part 1

Aunt Rosa had promised Priya three things about the canoe trip: loons, stars, and no cell service. By the second afternoon, Kettle Lake had delivered all three.

Now, as Priya lifted her paddle, she noticed that the far shore, which had been sharp and green all morning, was fading behind a grey haze. A gust wrinkled the water. Aunt Rosa, who had paddled these lakes for twenty years, stopped mid-stroke and turned her head to the west, listening.

Worked example

Let's make a prediction and pose checking questions

Stop after Part 1. Make a prediction using text clues and prior knowledge, then write questions to check it.

  1. Text clues: the shore is fading behind a grey haze; a gust wrinkled the water; Aunt Rosa, an experienced paddler, stops paddling and listens toward the west.
  2. Prior knowledge: haze and sudden wind can come before a storm. In Ontario, weather often moves in from the west. Experienced people notice danger early. From science: thunder is the sound of lightning.
  3. Prediction: A thunderstorm is coming. Aunt Rosa is listening for thunder, and they will head for shore.
  4. Checking questions: Will Aunt Rosa hear thunder? Will they get off the water? Will they reach shore before the storm hits? Each question tells you what evidence to watch for in Part 2.

Prediction: a storm is coming and they will head for shore. Checking questions: Will they hear thunder? Will they get off the water in time?

After the Haze, Part 2

Then Priya heard it too: a low rumble, like furniture being dragged across a floor upstairs.

"Thunder," said Aunt Rosa. "We're getting off the water. Now."

The nearest landing was the portage at the north end, marked by a yellow sign nailed to a cedar. They dug in their paddles. By the time the bow scraped gravel, the first fat drops were pocking the lake. They hauled the canoe high onto the shore, flipped it over and tied it to a stump. Then Aunt Rosa led Priya away from the water, past a tall, lonely pine, into a thick stand of young spruce, where they crouched on their packs.

Worked example

Let's check our prediction and adjust

Use the checking questions from Part 1. Was the prediction correct? What do we need to adjust?

  1. Will Aunt Rosa hear thunder? Yes: a low rumble... "Thunder," said Aunt Rosa. Confirmed.
  2. Will they get off the water? Yes: We're getting off the water. Now. Confirmed.
  3. Will they reach shore before the storm hits? Mostly: they land just as the first fat drops fall. Confirmed, but it was close.
  4. New information to adjust our understanding: they don't stay at the shore or take shelter under the tall pine. They move into a stand of young spruce, away from the water. Our prior knowledge of lightning safety explains why: lightning tends to strike tall, isolated objects and open water. Aunt Rosa knows what she's doing.
  5. New prediction for Part 3: They'll wait until the storm passes, then continue. Checking question: How will they know it's safe?

The prediction was confirmed. We adjusted our understanding of Aunt Rosa: she is not just cautious, she is knowledgeable about lightning safety. New prediction: they'll wait out the storm. Checking question: How will they know when it's safe?

Predictclues + prior knowledgePose questionswhat would prove it?Read onwatch for the evidenceConfirm or adjustchange the predictione.g. haze + gust + Aunt Rosa listening → "a storm is coming" → "Will she hear thunder?"
Predicting is a cycle. Checking questions tell you exactly what evidence to watch for, and each new part of the text lets you confirm or adjust.

After the Haze, Part 3

They waited, counting the seconds between each flash and its thunder: eight, twelve, twenty.

"It's moving away," Priya said, half rising.

"Not yet," said Aunt Rosa. "Thirty minutes after the last thunder. That's the rule."

Priya, whose legs had begun to cramp, wanted to argue, but she thought of the lonely pine by the shore, its top split and blackened by some storm years ago. She sat back down.

When they finally carried the canoe across the portage to the next lake, Aunt Rosa walking under it with the padded yoke on her shoulders, the sky was washed clean, and a rainbow arched over the water.

"Worth the wait?" asked Aunt Rosa.

Priya nodded, imperceptibly at first, then with a grin she couldn't hide.

Fixing comprehension problems

Complex texts have tricky words, long sentences and references back to earlier ideas. When you notice you're confused, name the problem, then choose a strategy that fits it.

ProblemExample from the storyStrategy that fits
I can't picture what's happeningthe first fat drops were pocking the lakeVisualize: picture big raindrops making little pits or dents in the water's surface.
I don't know what a pronoun refers toThen Priya heard it tooRead ahead (and back): it turns out to be the rumble, the thunder that Aunt Rosa was listening for.
A word is new and the context isn't enoughportage, yoke, bowConsult a reference: a dictionary or a labelled canoe diagram. A portage is a trail for carrying a canoe between lakes; the yoke is the padded crossbar that rests on your shoulders; the bow is the front of the canoe.
I don't understand why a character does somethingThirty minutes after the last thunderAsk a question (Why 30 minutes?), then consult another source: lightning safety guides advise waiting 30 minutes after the last thunder before going back out.
A long sentence loses mePriya, whose legs had begun to cramp, wanted to argue...Find the main clause: Priya wanted to argue. The part between the commas adds extra information.
Matching strategies to comprehension problems
Worked example

Let's untangle a complex sentence

Read this sentence from Part 1: Now, as Priya lifted her paddle, she noticed that the far shore, which had been sharp and green all morning, was fading behind a grey haze. What does it mean, and how is it built?

  1. Find the main clause (subject + verb that can stand alone): she noticed (that something was happening).
  2. **Find who she is** (cohesive tie): she = Priya.
  3. Find what she noticed: that the far shore... was fading behind a grey haze. The core is the far shore was fading.
  4. Set aside the extra parts: as Priya lifted her paddle tells when; which had been sharp and green all morning describes the shore before the change.
  5. Put it together in plain words: While Priya paddled, she saw that the far shore, which had looked clear all morning, was now hard to see because of haze.

Main clause: she (Priya) noticed that the far shore was fading. The other clauses add when it happened and what the shore was like before. That contrast (clear before, hazy now) is the clue that weather is changing.

Just for fun

Fun fact: Light travels nearly a million times faster than sound. That's why Priya and Aunt Rosa can count the seconds between the flash and the thunder: roughly every 3 seconds means the storm is about 1 km away.

Using other words to unlock new words

Imperceptibly looks hard, but you can break it apart: im- (not) + percept (notice, as in perceive) + -ible (able to be) + -ly (in a way). So imperceptibly means in a way that can hardly be noticed. Priya's nod starts so small you can barely see it, then becomes a grin. That shows she's a bit embarrassed to admit Aunt Rosa was right, but happy all the same.

im-notperceptnotice-ibleable to be-lyin a way+++imperceptibly = in a way that can hardly be noticed
Breaking imperceptibly into parts. Each part's meaning combines into the meaning of the whole word.

Monitor, name, choose

Monitor: Do I understand? Name the problem: a word? a sentence? a reference? a reason? Choose a strategy that fits: visualize, reread, read ahead, ask a question, break the word apart, consult a dictionary, diagram or reliable source. Then check whether it worked.

Hands-on activity

Prediction checkpoints at home

You need: a short story, chapter or news article you haven't read; sticky notes or a notebook; a dictionary (print or online with a grown-up).

  1. Before reading, list three pieces of prior knowledge: one from experience, one from another text and one from another subject (science, history, geography, math).
  2. Divide the text into three parts with sticky notes. At each stop, write a prediction and one or two checking questions.
  3. After each part, mark each question confirmed, partly confirmed or not confirmed, and write how you adjusted your understanding.
  4. Mark every place you got confused with a ?. Next to it, name the problem and the strategy you used (for example: new word, looked it up; long sentence, found main clause).
  5. Tell a family member which strategy helped most and why.

For parents and teachers

What this lesson teaches: Grade 7 students identify and explain prior knowledge from various sources, including other subjects (C2.1); make predictions, pose questions to check them and adjust their understanding (C2.3); select strategies such as visualizing, reading ahead, asking questions and consulting references to solve comprehension problems (C2.4); and read complex texts using knowledge of words, grammar, cohesive ties and sentence structures (C1.1). Using science knowledge to understand a story shows cross-curricular learning (A3.1).

How to help at home:

  • Pause during a read-aloud or a TV show and ask: "What do you predict? What question would tell us if you're right?"
  • When your child is stuck, ask: "What kind of problem is it: a word, a sentence, or why something happened?", then help them pick a matching strategy.
  • Encourage using a dictionary or a reliable website to check a word, then rereading the sentence.

Common difficulties:

  • Wild predictions with no evidence. Ask: "Which clue made you think that?"
  • Skipping confusion. Many readers keep going without understanding. Praise your child for noticing when they're confused.
  • Long sentences. Help them find who did what first, then add the extra parts.

About the story: After the Haze was written for this site; Kettle Lake is invented. The safety information is accurate and general: lightning tends to strike tall, isolated objects and open water; you should get off the water when you hear thunder; wait 30 minutes after the last thunder; sound travels about 1 km in 3 seconds. A canoe's yoke is the padded crossbar used to carry it on the shoulders, and the bow is the front.
