It's so good to be with you this morning.
Let's see if there's any mail.
Yay!
A postcard for Ms. Post.
Let's see what it says.
"Ms. Post, Frisbee is my favorite part of Rise and Shine.
"Will you please make sure that he is on the show today?"
I can do that.
You know, I was thinking about how much I love getting postcards with beautiful pictures of places all over Arkansas.
Did you know that one of my favorite things to do is hike to places that I can't get to or see if I'm just driving in a car?
There are beautiful places all over Arkansas where you can hike to see waterfalls, caves, and very high lookout points.
Well guess who loves to go on hikes with me?
That's right, Frisbee.
Where is that silly dog?
Frisbee!
- Hey!
- Hey boy.
- Hey.
- I have your leash.
Did you hear me say the word hike?
- I heard hike, but I don't like the leash.
I'm a free-range pup.
- A free-range pup.
Well, I can't take you quite yet, but how about a treat?
- Sure.
- Okay.
- I don't say no to treat.
Here you go.
(Frisbee noms) - Don't forget about the hike.
- Okay, okay.
Now the teachers in the teacher house want to take Frisbee to see the highest point in the whole state of Arkansas.
Now it's a pretty short hike to the top, and this place is called Mount Magazine.
When you get to the top, there's a mailbox and it has a register.
A register is like a notebook and you get to sign it to show everyone that you were up there.
Also at the top, there are rocks laid out that make the shape of Arkansas.
It is such a neat place.
I was also thinking about taking Frisbee to see some other high points in the states all around Arkansas.
Look at this map with me.
It has the highest places in all of our surrounding states labeled.
First, Arkansas has Mount Magazine at 2,753 feet.
Oklahoma has Black Mesa at 4,973 feet.
Missouri has Tom Sauk mountain at 1,772 feet.
Tennessee has Clingman's dome at 6,643 feet.
Mississippi has Woodall Mountain at 806 feet.
Louisiana has Driscoll Mountain at 535 feet.
And Texas has Guadalupe Peak at 8,751 feet.
Now real quick, there's something I need to explain called sea level, because when you see these numbers, we're talking about their elevation, or how high these places are above sea level.
And sea level just means the level or the height of the ocean.
Now, if you've ever visited the ocean, you know, that its level changes.
So we go by the average height of the ocean over years and years and years.
All the high places that we're talking about today are way above sea level.
Isn't it interesting to see all the states compared this way?
Now, Arkansas and Missouri look pretty close and this makes me wonder how many total feet in elevation Frisbee And I would reach in one week if we climb to the top of the highest points in Arkansas and Missouri.
Let's add them up.
Okay, Arkansas, we said is at 2,753 feet.
And Missouri is at 1,772 feet.
Okay, let's add them up.
We start in the ones place, three plus two is five.
And then we work left.
Five plus seven is 12 and that's two digits.
So you leave the two and you carry the one.
One plus seven is eight, plus seven more is 15.
Again, two digits, so we're gonna leave the five and carry that one.
One plus two is three, plus one is four.
So a total of 4,525 feet.
Wow, that is a whole lot of feet in elevation.
How many more feet in elevation do you think that they reached in Arkansas than they did in Missouri.
Now, when I hear how many more, it makes me think of subtraction.
So let's subtract these numbers now.
2,753 feet minus 1,772 feet.
Start in the ones and work left.
Three minus two is one.
Five minus seven, we can't do.
So we're gonna borrow from the seven, drop it to a six, and our five becomes a 15.
15 takeaway seven is eight.
We can't take seven away from six.
So we borrow from the two, drop it to be a one, and our six becomes a 16.
16 takeaway seven is nine.
So 981 feet.
They were almost a thousand feet higher in Arkansas.
Thank you for the postcard.
Have a great rest of the day.
Remember, keep a positive mindset, grow every day by reading and asking questions, and there's nothing you can't do if you put your mind to it.
I'll see you soon, bye.
- Hey, you didn't forget, did you?
- Let's go on our hike, Frisbee.
- Let's do it.
- All right.
