Learning goals
  • I can identify main and supporting ideas in literary and informational texts.
  • I can sequence the events of two plots that are told in alternating sections, and explain how they connect.
  • I can explain cause-and-effect chains in a story and in an informational text.
  • I can formulate a conclusion about a text using my analysis.

Words to know

plot
The series of events in a story.
multiple plots
Two or more storylines in one text, often told in turns, that may come together.
subplot
A smaller, secondary storyline that adds to the main plot.
cause
Why something happens.
effect
What happens as a result.
cause-and-effect chain
A series of events where each effect becomes the cause of the next.
main idea
The most important point a text or paragraph makes.

Remember from Grade 5

In Grade 5 you sequenced two plots, found main ideas, and followed cause-and-effect chains.

In Grade 6 you'll analyze both literary and informational texts on the same topic, explain how two plots connect, and use your analysis to formulate a conclusion.

Hook: Meanwhile, across town...

Movies often jump between characters: one scene shows the hero, then meanwhile... another character somewhere else. Books do this too. Sections switch between characters until their stories meet. As you read, keep track of who, where and what happens.

The Night the Lights Went Out (a story written for this website)

1. Leila Freezing rain ticked against the kitchen window. Leila taped the last wire to her science fair board: a small circuit with a battery pack, a switch and three LED lights. She flicked the switch. The lights glowed. "Perfect," she whispered.

2. Grandpa Sami Next door, Grandpa Sami watched the maple in his yard. Every branch was coated in shining ice, and the biggest branch hung low over the power line. He frowned, filled his thermos with hot tea, and put on his boots with ice cleats.

3. Leila CRACK. The kitchen went black. The fridge stopped humming. "The power's out!" called Mom from the hallway. Leila felt her way back to the table, found her board, and flicked the switch. Three tiny lights glowed in the dark.

4. Grandpa Sami The big branch lay across the snowy yard, and the power line sagged. Grandpa Sami stayed far away from it and phoned the power company to report it. Then he crossed slowly to Leila's back door, one careful step at a time, thinking, They'll have no light at all.

5. Together When Grandpa Sami opened the door, he found the whole family around the kitchen table, sharing the glow of Leila's science project. He laughed and poured the tea. "You built a lamp," he said. Leila looked at her circuit. "I think I just found the last section of my project," she said. "Circuits in an emergency."

Two plots told in turns: Leila's sections (1 and 3) and Grandpa Sami's sections (2 and 4) join in section 5
Worked example

Let's sequence the two plots and explain how they connect

Sequence each plot separately. Then explain how and why they come together.

  1. Leila's plot: finishes her circuit → the power goes out → she turns on her battery-powered LEDs.
  2. Grandpa Sami's plot: notices the ice-covered branch over the power line → prepares tea and boots → finds the fallen branch, stays away from the line, reports it → crosses to Leila's house.
  3. Order of events overall: some events happen at the same time (the CRACK in section 3 is the branch falling, which Grandpa sees in section 4).
  4. Connection: both plots are caused by the same event: the ice storm and the falling branch. They meet when Grandpa arrives, worried about the dark, and finds Leila's circuit already lighting the room.
  5. Why two plots? We know something Leila doesn't (the branch is about to fall), which builds suspense, and Grandpa's worry makes the ending, Leila's lamp, more satisfying.

The two plots run side by side, are caused by the same branch falling, and join in the kitchen. Telling them in turns builds suspense and lets readers see both characters' thoughts.

Cause-and-effect chains

In a chain, each effect causes the next event:

freezing rain → ice coats the maple branch → the heavy branch falls on the power line → the power goes out → Leila turns on her battery circuit → Leila gets an idea for her project.

Some events have more than one cause: Grandpa crosses the yard because the power is out and because he cares about his family.

The cause-and-effect chain in the story. Each event causes the next, and the informational text Ice Storms in Ontario explains the same first steps.

Ice Storms in Ontario (an informational text written for this website)

Ice storms can cause serious damage. During an ice storm, rain falls through cold air near the ground and freezes as soon as it touches trees, roads and power lines. The ice can build up into a thick, heavy coating. Branches and even whole trees can break under the weight, and they can fall onto power lines. Ice-coated lines can also snap. In January 1998, a huge ice storm left many people in eastern Ontario and Quebec without electricity, some of them for weeks. That's why safety experts recommend that families keep flashlights, batteries and water in an emergency kit.

Worked example

Let's find the main and supporting ideas

What is the main idea of Ice Storms in Ontario, and what are the supporting ideas?

  1. The first sentence states the main idea: Ice storms can cause serious damage.
  2. Supporting idea 1 (how): rain freezes on contact and builds a heavy coating.
  3. Supporting idea 2 (effects): branches and trees break and fall onto lines; lines can snap.
  4. Supporting idea 3 (example): the 1998 ice storm left many people without power, some for weeks.
  5. Supporting idea 4 (solution): families should keep emergency kits.

Main idea: ice storms can cause serious damage. Supporting ideas: how ice builds up, what it breaks, a real example from 1998, and how to prepare.

Formulating a conclusion from your analysis

Put the story and the informational text together. The story shows the same cause-and-effect chain that the informational text explains (ice → falling branch → power out). Both show preparation matters: Leila's battery circuit and Grandpa's ice cleats and thermos helped.

Conclusion: Being prepared for ice storms, with things like flashlights and batteries, helps families stay safe and comfortable when the power goes out. This conclusion is supported by both texts.

Just for fun

Every "meanwhile" in a story is secretly a teleporter. One word, and zoom! You're next door with Grandpa Sami.

Safety: downed power lines

Grandpa Sami did the right thing: he stayed far away from the fallen line and reported it. Never go near or touch a fallen power line or anything touching it. Tell an adult right away, who can call the power company or 911.

Hands-on activity

Two-colour timeline and emergency kit check

You need: two colours of pencil, a long strip of paper, a grown-up.

  1. Draw a timeline. Put Leila's events in one colour above the line and Grandpa Sami's events in another colour below it. Show which events happen at the same time.
  2. Draw a cause-and-effect chain of at least five links for the story.
  3. With a grown-up, check your home's emergency kit: flashlight, extra batteries, water, a first-aid kit. Make a list of anything missing. (Do not use candles without a grown-up.)
  4. Write a 3-sentence conclusion that uses evidence from both texts.

For parents and teachers

What this lesson teaches: Grade 6 students analyze literary and informational texts by identifying main and supporting ideas, sequencing events in multiple plots, explaining cause and effect, and formulating conclusions (C3.3).

How to help at home:

  • In books or shows that switch between characters, ask: "Where are we now? How will these stories connect?"
  • Talk about chains of events in daily life (It snowed → buses were cancelled → ...).
  • Use the activity to check your family's emergency kit.

Common difficulties:

  • Mixing the two plots into one list. Use two colours.
  • Single causes only. Ask: "Was there another reason too?"

Safety: Teach children to stay away from fallen power lines and to tell an adult. Candles should only be used with an adult present.

Facts used: Freezing rain freezes on contact with cold surfaces; heavy ice can break branches and power lines. The January 1998 ice storm caused long power outages in eastern Ontario and Quebec. Emergency kits with flashlights, batteries and water are widely recommended. The story was written for this site.
