Welcome back to Teaching in Room Nine, the area's largest classroom.
I'm Mrs.
Forth from the Rockwood School District.
And boy, have we been having fun learning together this summer?
We've talked all about camping and space.
Last week we talked about pets.
That's right.
And in this week, is all about the rain forest in Teaching in Room Nine.
You're gonna have so much fun discovering new things about the rainforest this week.
I love the rainforest because it's so different than where we live.
And I love learning about different places.
It's fascinating to me.
So of course with me, Mrs.
Forth, we're gonna be reading about the rainforest.
So I have this book right here, "Baby Animals in the Rainforest Habitats".
This is written by Bobbie Kalman and published by Crabtree Publishing.
So thank you always to the publisher and the author for allowing us to enjoy these books.
And as we read about the rainforest, we're gonna be learning new information.
Which means, we're gonna be reading nonfiction.
And as we read nonfiction, I always like to practice main idea.
You've heard of main idea before?
I bet you have.
I bet you talked about it a lot, whether you were in-person in school last year or virtual.
That's right.
It's just something that readers do, finding the main idea.
What is this mostly about?
And we're gonna be practicing that all week as we read and learn about the rainforest too.
We're gonna be trying out three strategies this week together to find the main idea.
The first strategy that we're gonna try is, noticing those bold words.
Those bold words are the ones that pop out.
They're really dark.
And those are key words.
The author chooses to make those bold because they're pretty important.
They might be new words to us or they might be the most important words in the part that we're reading.
So we're gonna pay attention to bold words, and that's exactly what we're gonna do today.
Another strategy we're gonna work on together this week is really looking at all the text features and putting them together.
Because when you pay attention to all the text features, sometimes you can figure out what the main idea is.
And then the last strategy that we're gonna try, is notice what repeats.
Sometimes the author uses the same words over and over again on a page.
And that's a big clue that, hey, these words are important.
I bet they're related to the main idea.
So let's jump into reading and practice one of these strategies.
We're gonna really pay attention to the bold words.
As we notice bold words, I'm gonna write them down on a sticky note.
You can do that too.
If you have a white board or a sticky note, feel free to jot them down with me.
And then we're gonna take a look at it and think, hmm, what do these words mean?
And yeah, are they gonna help us find the main idea?
Remember, the main idea is, what is this mostly about?
What really did the author want us to know on this part?
"Baby animals in Rain Forest Habitats".
And I'm grabbing my sticky notes, are you?
Got my sticky notes and my Sharpie and I'm ready to go.
Okay.
We're gonna be looking for those bold words as we read and learn about baby animals in the rainforest habitat.
"Baby Animals in Rainforests Habitats" by Bobbie Kalman.
Oh, I love primates.
I could watch them all day at the zoo.
We are noticing a table of contents.
That's a text feature that we see a lot of in nonfiction books.
So these are all the things that we could read about.
And remember, in nonfiction, if you've read with me before any nonfiction book, I don't always read it from the beginning to the end.
Do I?
Sometimes I like to hop around.
Yeah.
Would you like to hop around?
Okay.
What do you think?
Let me read all of the parts and you tell me what most interests you today and we'll kind of take a vote.
What is a habitat?
Where on earth?
Oh, that must tell us where rainforests are.
What do they need?
Rainforest babies, layers of the forest, mammal mothers, rainforest birds.
What is a life cycle?
Water babies, a rainforest food chain.
And then at the end we have our index which are important words for us to know.
So what are you thinking?
Go ahead, shout out at me.
Okay.
I'm hearing a lot of rainforest babies.
You wanna know about the little cute rainforest babies?
I like that too.
Let's go ahead.
What page do I need to go to?
Page 10.
I'm gonna hop to page 10.
Let's see.
All right.
Taking a look at page 10.
Are you noticing any bold words?
No, me either.
That's gonna be really hard for us to work on that strategy.
So what do you think we should do?
Just read ahead?
Find a page with bold words so we can actually practice the strategy.
I like that.
Okay.
You tell me to stop when you see pages with bold words.
Oh, okay.
I hear you.
I hear you.
Stop you definitely...
Okay.
I think that's gonna help us out as we practice this strategy.
Let's go ahead and focus just on this paragraph right here to help us figure out the main idea.
So you can tell this as a new book.
So I really got to flatten it so you can see.
Zoom in.
And here we go.
Where on earth?
Tropical rainforest can be found on every continent except Europe and Antarctica.
Okay.
I'm gonna write continent down.
You write that too if you've got your sticky note or your white board.
Continent.
Okay.
A continent is a huge area of land on earth.
Tropical rainforests are near the equator.
Equator.
Equator.
I'm gonna write that down.
It's a bold word.
Equator.
You're right here?
I know it's bold because it's popping out at me.
It's nice and dark.
The equator is an imaginary line that divides earth into two parts.
The weather at the equator is always hot.
Millions of species or types of plants and animals live in tropical rainforest.
Yep.
You're right.
Another bold word, species.
Okay.
What I love that Bobbie Kalman did is, not only did she let us know which words she thinks is important by bolding, but she also explained what the words were.
Did you notice that?
After there was a bold word, the next sentence or the part after the bold word explained what it is.
So, a continent is a huge area of land on earth.
The equator is the imaginary line that divides the earth into parts.
Species is another word for types.
So it really helps us to understand.
And then this picture helps us too.
Here's our earth.
Here's all the continents.
Here's the equator.
So what would you say, is the most important part here?
What did we learn on this?
Yeah.
Almost every continent has a rainforest.
Rainforests are found near the equator.
I like that.
I like that because if you know where the equator is then you know that there's a lot of continents that are around the equator, right?
So I think that's a great way to say the main idea.
I would say that rainforest can be found near the equator.
Rainforests can be found near the equator.
Yeah.
That's the most important part about that page?
Although there's lots of information, if you were to read that page and then somebody say, hey, what's that about?
Would it make sense if you said, rainforest can be found near the equator?
Yeah, absolutely.
And it even matches the heading.
The heading, where on earth?
Where are they?
Well, they can be found near the equator.
Air high-five.
Okay.
I'm gonna find another section of this book that has bold words and see if we can try it again.
Oh, here we go.
This one.
Layers of the forest.
Rainforest actually have different layers.
Let's read to find out and then try to identify the main idea by using our new strategy.
And remember, our strategy is to pay attention to those keywords or bold words.
Okay?
Many trees grow in rainforests.
Different animals live in the different layers of the forest.
The layers are called emergent, canopy, understory, and forest floor.
The emergent layer is at the top of the tallest trees.
Many birds, bats and monkeys live in or visit these giant trees.
The next layer down is the canopy.
Sloths, birds and tree frogs live in the upper parts of these trees.
The next layer down is the understory.
Shaded by the taller trees, it is a cool dark place where small trees and bushes grow.
Many plants in this layer have large leaves to help catch sunlight.
Margays, jaguars and tree frogs live there.
And the forest floor layer is the ground where insects as well as giant anteaters live.
So I can almost visualize all the layers, right?
That's like the very top and then the middle and getting lower and then finally the ground.
So let's think.
Hmm.
Let's write down those bold words and see if they can help us figure out what the main idea is.
Okay.
I'll get my sticky note and write down the bold words.
Can you help me find them?
Yeah.
There was a bunch, all in a row here.
So we have layers, emergent, canopy, understory and forest floor.
Hmm.
So really what did we learn on this page?
What was this mostly about?
Yeah, that the rainforest has four layers.
The emergent, canopy, understory and forest floor.
Yeah.
That's interesting.
And different plants and animals live on those layers?
Yeah, it kind of tells us where you can find the different plants.
So much information.
So if I said, oh, what was this about?
What would you say?
Go ahead and tell me that main idea.
Great.
Anything else?
There are four layers in a rain forest.
Each layer has different animals.
I love it.
Main idea.
There are four layers in a rain forest.
Each layer has different animals.
That's perfect.
Readers, what a fantastic job?
So as you are reading nonfiction books, I want you to try this out.
I want you to notice when there's bold words, and I want you to write those bold words down.
And afterwards, I want you to think about what you learned on this page.
Look at those bold words and see if it can help you tell what the main idea is of the part that you read.
What's the most important part?
Really what did the author want us to know?
You did it twice already and you did a fantastic job.
Ooh, great question.
What if there aren't bold words?
Like what happened on the page that we turn to page 10?
Page 10.
Yeah.
No bold words.
But we're gonna talk about that tomorrow.
So it sounds like you're gonna have to come back and learn another strategy to find main idea other than looking out for bold words, because you're right, not all books have bold words.
So I hope to see you tomorrow so you can learn yet another way for us to find the main idea in our nonfiction books.
Have fun at math.
Bye.
- Hello, welcome to the rainforest.
Thank you Mrs.
Forth, for an amazing reading lesson.
(sighs) I am really excited to learn about the rainforest this week and learn some math.
So as we get started, I am going to share some information that I learned from The Smithsonian, and it is about each of the different layers.
And so today, we are gonna learn about the emergent layer, which is the highest layer of the rainforest.
The layer's made up of the very tallest trees and it's bright and sunny and there's a lot of space up there.
So I want you to stretch out your arms and fly around the room that you're in like a green-winged macaw.
Woo.
Because a green-winged macaw is a one of the animals that live in the emergent layer of the rainforest.
And animals who can fly and have really good balance and are excellent climbers live in the emergent layer of the rainforest.
So the green-winged macaw has long, strong wings that they use to fly from tree to tree while they look for fruits and nuts and leaves.
And they also have really strong feet.
So when you squeeze your toes, and they use their claws to grip onto the branches which they really need to do.
(laughs) And some of the other animals that live in the emergent layer with the green-winged macaw are the blue morpho butterfly and the howler monkey.
So now we're gonna take off and fly to the math treetop of the emergent layer.
Woo.
(claps).
Okay.
So in the emergent layer today, we are going to be adding multiples of 10 to any number.
Okay?
Now, this is a really, really important skill and it actually took me a kind of a long time to learn this skill.
And what is important about this skill is understanding place value.
So before we get started with adding multiples 10 to any number, let's review what we know about place value, right?
So we know that there is a hundreds place, a tens place, and a ones place, right?
And when you write a number... Whoops.
I don't know why I feel the need to make those so big, but I do.
When you write a number, the digits fall in to certain places, right?
So this is saying that you have three ones.
One, two, three.
Okay.
You have three ones.
Then over here, you have 10, the tens, and you have two groups of 10, which is actually two groups of 10 ones, right?
Crazy.
And then you have one group of 100.
Okay?
So which is actually 10 tens.
Okay?
So, remembering that is really important.
You have to know the hundreds place, the tens place, the ones place.
Okay?
Because you are going to use that information to add multiples of 10.
So if we were to build the number... Let me show you on this board, actually.
Okay.
We are going to build the number 23.
Okay.
So I have two tens and three ones.
So I know that this number is 23 and I could show that 23 in expanded form as well.
23.
Okay?
Now, what if I wanted to add 10 to this number?
What do you think it would be?
Do you think the digit in the ones place is going to change at all?
Okay.
I agree.
I don't think it will because if I'm adding 10, the only digit that should change is the tens place.
And when I add 10, what's my number now?
Yes.
Now when I added 10, I increased the value of the tens place by 10.
So now instead of 20, I have 30, but I still have three ones.
So when you're adding 10 to any number, the only place value that is gonna change is the tens place.
Okay?
Okay.
So we just did 23 plus 10.
And I can look at this and quickly figure it out because I realized, oh, I'm only changing, I'm adding 10, so I'm only changing the value of the tens place.
Awesome.
Okay.
Let's try another one and see if you can do this.
Okay.
Count how many tens do you have.
Good.
So we have 10, 20, 30, 40, 50.
We have five tens, and then we have, 51, 52, 53, 54.
54.
So if I add 20 to this number, what is the only place that's going to change?
Yeah, the tens place.
I'm gonna add 20.
10, 20.
So now, you're right.
I have 74.
Awesome.
See, adding 10 is a really, really really important skill.
Okay?
Okay.
Now let's see if we can try it without the blocks this time.
Can you figure these out without using the blocks?
For the first time, we can always use them if we need them.
So if I have 62 and I add 30, what do you think the answer is?
Good.
You know the ones place is going to stay the same.
And then you have six and you're adding 10 to six.
So six, seven, eight, nine.
92.
Let me show it to you.
So we have 62, 20, 30, 40, 50, 60, and then we're gonna add 30.
So here's 60 and I'm gonna add 30.
So now we have 92.
Awesome job.
Okay guys.
(sighs) So we're gonna keep using the same strategy but I'm gonna try and make it a little harder.
What if I did this?
Whooo.
Now the number has three digits.
It has a hundreds, a tens and a ones place.
We're adding 20 to it.
Okay.
So I'm fresh out of hundreds, so I'm gonna pretend that this is a hundred right here.
Okay?
So 130, one, two, three, four, five.
135.
Now I have a hundreds place, is the tens place still the only place that's gonna change?
Yes, you're right.
So now I'm just adding 20 to the tens.
10, 20, right?
So now let's count the tens.
I still have 100, 10, 20, 30, 40, 50, and then five ones.
155.
All right.
Come back here tomorrow and we are gonna subtract with multiples of 10.
