Learning goals
  • I can identify the main and supporting ideas in literary and informational texts.
  • I can sequence the events of a story with more than one plot.
  • I can record relevant information in notes or organizers.
  • I can explain cause-and-effect relationships, including chains of causes and effects.

Words to know

plot
The events of a story, in order.
multiple plots
Two or more storylines happening in the same text, often in different places, that may come together.
relevant
Connected to your purpose or question; important for what you need.
graphic organizer
A chart or diagram for organizing ideas, such as a timeline or T-chart.
cause
The reason something happens.
effect
What happens because of a cause.

Remember from Grade 4

In Grade 4 you identified main ideas, sequenced a main plot and a subplot, and followed cause-and-effect chains.

In Grade 5 you will follow stories that switch back and forth between characters in different places, record relevant information in notes, and explain causes and effects in both stories and informational texts.

Hook: Two places at once

Some movies show one character in one place, then cut to another character somewhere else. You have to keep track of both. Books do this too! Read this story, written for this website. Watch for the switches.

The Ice Storm

(1) On Friday night, freezing rain coated Leo's street in Ottawa with ice. At 9 p.m., the lights flickered and went out. Leo and his dad lit candles and got out the camping lantern.

(2) Meanwhile, about 200 kilometres away, Leo's sister Ana was at a hockey tournament in Kingston. Her team won its game, but the coach had bad news: "The highway is closed because of ice. We're staying another night."

(3) Back in Ottawa, the house grew colder. Leo's dad remembered their neighbour, Mrs. Choi, who lived alone. Leo and his dad carefully walked over with their lantern. Her house was freezing, so they invited her to stay with them by their wood stove.

(4) In Kingston, Ana couldn't sleep. She worried about her family in the dark. Her coach let her call home. "We're fine," said Leo. "Mrs. Choi is teaching us a card game!"

(5) On Sunday morning, the power came back on in Leo's neighbourhood. Mrs. Choi made pancakes to say thank you.

(6) That afternoon, the highway reopened, and Ana's team bus pulled into the driveway just as the last pancakes came off the pan. The whole family, and Mrs. Choi, sat down to eat together.

Worked example

Let's sequence the two plots

List the events of each plot in order, then show where the plots meet.

  1. Signal words show switches: Meanwhile, about 200 kilometres away (switch to Ana); Back in Ottawa (switch to Leo); In Kingston (switch to Ana).
  2. Leo's plot: (1) power goes out → (3) they bring Mrs. Choi to their warm house → (5) power returns; Mrs. Choi makes pancakes.
  3. Ana's plot: (2) highway closes; team stays → (4) Ana worries and calls home.
  4. The plots meet: (6) the highway reopens and Ana arrives home for pancakes.
  5. Notice that the phone call (4) also links the plots before they meet.

Leo: 1, 3, 5. Ana: 2, 4. Together: 6. Switch words like Meanwhile and Back in Ottawa help you keep track.

Worked example

Let's find causes and effects

Find three cause-and-effect relationships in The Ice Storm. Then find a chain.

  1. Cause: freezing rain coated everything in ice. Effect: the power went out (ice can bring down power lines).
  2. Cause: ice on the highway. Effect: the highway closed, so Ana's team had to stay another night.
  3. Cause: Mrs. Choi's house was freezing. Effect: Leo and his dad invited her to stay by their wood stove.
  4. Chain: freezing rain → power out → houses grow cold → Mrs. Choi stays with Leo's family → she makes pancakes to say thank you.

Freezing rain causes the power outage and the highway closure. One chain leads all the way to the thank-you pancakes.

Main and supporting ideas in an informational text

What Is Freezing Rain? (written for this website)

Freezing rain forms in a special kind of weather. Snow falls from a cloud into a layer of warm air, where it melts into rain. Then the rain falls through a thin layer of freezing air near the ground. The drops become super-cold but stay liquid. When they hit cold roads, trees and power lines, they freeze instantly into a coat of ice. Heavy ice can snap branches and bring down power lines. In January 1998, a huge ice storm hit eastern Ontario and southern Quebec, and some homes were without power for weeks.

Recording relevant information

Relevant means connected to my purpose. If your purpose is learn how freezing rain forms, the relevant facts are the layers of air and freezing on contact. The 1998 storm is interesting, but less relevant to that purpose.

Tips for good notes:

  • Write key words, not whole sentences.
  • Use your own words.
  • Use arrows to show cause and effect or sequence.
  • Choose an organizer that fits: a timeline for sequence, a T-chart for main idea and details, boxes and arrows for cause and effect, two timelines for two plots.
Just for fun

Why are stories with two plots so polite?

They always say Meanwhile... before they change the subject!

Keeping track of two plots

Use two colours: one for each character. Write the place at the top of each section. Watch for switch words: meanwhile, at the same time, back at, across town, in Kingston.

Hands-on activity

Two-colour timeline

You need: a long strip of paper (or tape 2 sheets together), two coloured pencils, and a chapter book or movie that follows two characters.

  1. Draw two lines across the paper, one for each character.
  2. Add each event on the right line, in the right colour, as you read or watch.
  3. Draw lines where the two plots connect or meet.
  4. Add one cause-and-effect chain with arrows.
  5. Retell the story to a family member using your timeline. Can they follow both plots?

For parents and teachers

What this lesson teaches: Grade 5 students analyze literary and informational texts by identifying main and supporting ideas, sequencing the events of multiple plots, recording relevant information, and explaining cause and effect (C3.3).

How to help at home:

  • When watching a show that switches between characters, pause and ask: "Where are we now? What's happening in the other storyline?"
  • Ask "Why did that happen? What happened because of it?"
  • Practise key-word notes together from a news story or recipe.

Common difficulties:

  • Losing track of switches. Use two colours or two timelines.
  • Copying instead of noting. Cover the text and write what you remember in key words.
  • Mixing up cause and effect. Ask which happened first.

About the facts: Freezing rain forms when snow melts in a warm layer of air and the rain then falls through a shallow freezing layer, freezing on contact with cold surfaces. The January 1998 ice storm affected eastern Ontario and southern Quebec, and some homes were without power for weeks. The Ice Storm story was written for this site. Safety: candles and wood stoves need adult supervision.
