📝 Main Idea and Supporting Details Activity

In this section, the teacher introduces the goal of the activity: identifying the main idea and supporting details from a reading passage about water striders. Students are asked to read an article and use their pencils to highlight key information. The teacher then reads the passage aloud, allowing students to mark any additional points. The passage describes water striders, insects that can walk on water due to their lightweight bodies and long legs. The students are encouraged to engage with the text by marking significant details to help answer questions later.

05:01

🔍 Answering Text-Dependent Questions

The teacher leads a question-and-answer session based on the passage, encouraging students to find and highlight key facts from the text. They answer questions about the water strider’s resemblance to a mosquito, its size, and its speed. Students must provide the paragraph and sentence number for their answers, reinforcing the importance of locating and referencing specific evidence from the text. The activity continues with more questions about water striders’ behavior, such as whether they can be found on land and what they eat. Students work in teams, using spiders as Bingo markers to track their progress.

🤔 The Importance of Water Striders’ Vision

This part focuses on deeper comprehension questions, such as the significance of water striders’ vision. Students discuss what would happen if water striders lost their vision, with one group proposing that it would make them slower, while another suggests it would make them more vulnerable to predators. The teacher guides students to understand the bigger impact of vision loss—becoming prey. The class also discusses how water striders don’t sink due to their lightweight bodies and legs. Through collaboration, students refine their answers based on evidence from the text.

15:06

🦟 Classifying Water Striders

The final section of the lesson focuses on the concept of classification. The teacher uses the example of food categories to explain how to classify water striders. Students are guided to identify water striders as insects based on the text, which notes that they have six legs, like all insects. The session ends with students justifying their answers using text evidence, such as the fact that water striders spend most of their time on water, where they eat and catch their meals. The teacher encourages students to highlight these key details and rewards them with positive reinforcement.

Transcripts

What are we here to learn?

Main idea.

We are I can identify the main idea and supporting details

from what I read and create a summary using the supporting details.

Give yourself a pat on the back if you're ready.

Okay, let's turn those papers over that you have on your desk.

This is your opportunity to do a closed reading activity

where you read that article.

You can use your pencil to highlight any information

that you think will help you in finding the main idea.

We're going to be using the reading cards, the blue reading cards,

so when you're done, simply turn it over

so we'll know when we can move on.

You may begin. Okay, stop.

Thank you for all reading that passage on your own

and marking key information that you found in the text.

I will now read it to you.

Feel free to also mark something if you don't feel you

got it on your read.

Feel free to mark it at this time.

Water striders; imagine yourselves zooming across

the top of a pond or lake without sinking in.

While this might be hard for you to do, it is easy for a water strider.

A water strider is a water bug that looks like a large mosquito.

What makes it different from a mosquito

however is the fact that it can walk across the water.

You can find water striders on the surface of some

ponds, marshes, and still water.

Water striders do more than just walk across the water.

They also catch and eat their meals on the water as well.

Additionally, because they spend more of their time on the water,

water striders feed mostly on other insects that live near water.

In fact, water striders only go inland

when rain or strong winds force them off the water.

The design of a water strider's body makes it easy

for the insect to walk on the water.

Its body is only one half inch long

and it is covered with scales that keep it from getting heavy and sinking.

Like all insects, the water strider have six legs.

The front pair of legs are short while the

middle and back legs are very long.

The longer legs can spread over a larger area of water

and are useful for rowing and steering across the water.

No one leg is heavy enough to sink the insect.

Water striders also have very good vision and can move quickly.

These traits help keep them from becoming prey or food for other insects.

Now it's time for us to work on some text dependent questions.

We are going to play Bingo while we answer the questions today.

You have some spiders that you're going to use as your markers.

Here's how the game will be played.

Your entire group is one team.

I will tell you what row or column we're working on at that time.

Whenever I show you what row or column we're working on,

your team is going to try to find the answers to those questions.

They must be highlighted in the text,

and you must be able to tell me where you found it

with the paragraph and the sentence number.

Here we go.

The first thing we're going to work on is across the top,

what insect does a water strider resemble?

How would you describe the size of a water strider?

What fact can you select to show the speed of a water strider? Go.

Okay. Put a spider right there.

What's your answer going to be?

A large mosquito.

Okay.

You're going to find it in the text.

You have to be able to highlight it to use it for an answer.

What fact can you select to show the speed of a water strider?

Abby has an answer. Share it Abby. What did you see?

I saw sentence five group one water striders also have...

Striders!

Go on and finish.

Good vision and can move quickly.

Awesome job. Awesome. Okay. I heard my first group.

Water striders, I heard it. Okay, let's see if they've got it.

Now they're going to help you out because remember when we respond,

the first thing we do is tell the paragraph then the sentence number,

then we give our fact but then we answer our question.

And I'm going to type the answer up here

that way you'll make sure you've highlighted the correct section.

Here we go. Which insect does a water strider resemble?

Hudson, can you tell me where you found that answer?

Paragraph two, sentence one,

a water strider is a water bug that looks like a large mosquito.

Okay. So he said paragraph two sentence one. What is your answer then?

A large mosquito.

A large mosquito. He is correct. Looking good. Next one.

How would you describe the size of a water strider?

How would you describe the size?

I'm still on this table because they were the first group.

Victor, can you answer that question for us?

Paragraph four, the second sentence says,

"Its body is only one half inch long."

Ready? Looking good. Two out of three.

Let's see if they can get the last one.

What fact can you select to show the speed of a water strider?

Dylan, it's your turn.

Paragraph five, sentence one says,

"Water striders also have very good vision and can move quickly."

She got it. Ready? Looking good. Great job.

Now we are moving to the center column.

The next question is; since the title of the article is water striders,

would you find a water strider on land?

Next one, how would you summarize what water striders eat? Go.

But you'll need to highlight that answer to be able to put a spider there.

You'd have to highlight that. Did you highlight it when we went over it?

Us three did.

Okay. Make sure your whole group has that highlighted

and you can put you a spider there.

If not, in a minute, you won't be able

to use it. Does everyone have it? Okay. Now you can. Now go.

We think that you possibly could find it. I mean possibly--

But remember that we worked on opinions and our prior knowledge.

We can't bring any of that to the text

so you have to be able to find it in that passage to highlight it.

This is where it spends most of the time.

Okay, but the question is, look;

since the title of the article is water striders,

would you find a water strider on land?

No.

I remember one of the paragraphs was telling about

when something pushes it off.

Okay. Find that. You're getting there. Find it.

She said I remember but now help her find it.

She remembers it talked about it pushing it off.

Striders!

I heard one right here.

Let's give everyone another second or two

to work on it a little bit further,

but you are the group that I heard.

Okay, stop. Emily's group up here thinks they have the answers.

Remember, if your group didn't get to it,

you need to listen to where you can find the information

in the text and highlight it.

If you highlight it,

you can give yourself a spider

because you need all of the spiders you can get on there.

Okay Emily, here we go. It says,

"Since the title of the article is water striders,

would you find a water strider on land?"

No. It's a no because it says on paragraph three on the last sentence,

"In fact, water striders only go in land

when rain or strong winds force them off the water."

That is the text she needed. Now Emily, let me ask you that question.

The question is; would you find a water strider on land?

No. Not usually.

Okay, but listen to it one more time.

In fact, water striders only go inland

when rain or strong wind forces them off the water.

Do you know what inland is Emily?

Yes ma'am.

Okay. Will they ever go on land?

Yes, when it's raining or it's blowing really hard wind.

Okay. When they're forced that way.

Even though they're called water striders,

you could possibly find them on land, okay.

Next one, Josh, answer this one for me.

How would you summarize what water striders eat?

Paragraph three, second sentence, well, third sentence, it says,

"Additionally, because they spend most of their time on water,

water striders feed mostly on insects that live near water."

Let's give both Emily and Josh our cheer. Looking good.

Again, if you highlighted that, even if your group didn't make it,

you can put you a spider there.

Next row, here we go. Bottom row. Bottom row.

What would happen if water striders lost their vision,

you should already have this one answered,

and how would you show your understanding that water striders don't sink.

Go.

Water striders also have very good vision and can move-

Yeah but that didn't say what would happen

if water striders [inaudible 00:11:13].

Josh, that's wrong. It's wrong Josh. Josh, that is wrong...

Their striders lost their vision?

Striders!

All right, stop. We've got another group.

I like how we have different groups finishing.

What would happen if water striders lost their vision?

Adriana, share with us where you found that answer.

In paragraph five, sentence one it says water striders also have

very good vision and can move quickly.

Okay, so what would be your answer to the question,

what would happen if water striders lost their vision?

They won't be able to move very quickly.

We're thinking a little deeper though, they lost their vision.

This is going to have a bigger impact on their lives.

Let's let Ella's group help us out on that.

They highlighted a different fact and see

if this will change your view here. Right here.

Well on paragraph five, the last sentence it says,

"These traits help keep from them coming prey

and if they lost their vision,

they'd probably become prey because they wouldn't know

where they were and they might come into where the prey is."

Very good. Let's go ahead and give her the cheer. Looking good.

Does that group see how that answer got changed?

You were right. They're not going to move as fast,

but is that the most important fact?

No, becoming prey is a lot more important.

All right. And the last one on the right it says;

how would you show your understanding that water striders don't sink?

Katie, help me out on that. Where did you all find your information?

Their body is only one half inch long,

and it's covered with scales that would keep them from heavy sinking.

Okay. That's paragraph four?

It's sentence two.

Okay. I agree that kind of shows you they're not going to sink,

but I feel like another group got another fact that

was just a little bit stronger.

You're not wrong. You are not wrong,

but let's see if someone can support it a little bit more.

Jayda, can you share that with us please?

Paragraph four, the last sentence says,

"No one leg is heavy enough to sink the insect."

Okay. So we know it's not going to sink

because not even one of its legs is heavy enough to sink it.

All right. I guess you can tell what we have left. The middle.

Two questions, you may go. Let's see if another group can get it.

Okay. Can you share with your group what classify means?

Classify means like how would you describe it.

Okay. A little bit more than that. A classification. Think of food.

Are there different types of food? Okay.

Name some types of food for me.

A sandwich, fruit, meat, do you have anything else? Do you have any sugar?

Nothing sweet? Not a brownie or anything? A granola bar.

Those are classifications. Now, you're looking for a classification.

A type. There's something in the text that's going to help you with that.

How would you classify it?

Think about like the big word 'food'

and then we broke it into like categories.

What category is a water strider going to fit into?

We need to work on classify over here? Okay. So we put it into categories.

I want you to take the word 'classify' and think of a category.

You know what a water strider,

what category would it fall into in this text that it tells you?

It tells you what that is. Where did you find that?

Let him find it for you.

Where did you find that Graham?

What category are we going to put it in?

Paragraph four, you're there bud, find it.

Striders!

Like all insects, the water strider has six legs.

Okay. So that was paragraph four. Right here.

Like all insects. Graham. Give me five. Okay. I had a group over here.

I heard them.

This one was a little challenging because we had some vocab.

All right, have a seat. Have a seat.

I think our board is full. Let's see if we can finish our answers.

Classify stumped some people. The word classify.

That's some vocab we're going to need to work on.

How would you classify a water strider?

Shelby, can you tell me where you found that?

We found it in paragraph four sentence three.

Okay. Will you read it for me?

It says, like all insects, the water strider has six legs.

So how would you classify it? It is a what?

An insect?

It is an insect. We had to work on classify. Okay? Classify.

And then the last one for today I'm questioning is;

what information would you use to support the view

that water striders spend most of their time on water.

Brenna, can you answer that for me?

In paragraph three, the first sentence, the first two sentences, it says,

"Water striders do more than just walk across the water.

They also catch and eat their meals on water as well."

Eat and catch their meals on water and then what was the first sentence

because I think that does help justify your answer.

They do more than just walk on water.

Okay. They do more than walk. They do more than walk.

Both of them get the cheer. Looking good.
