Today we are talking about math and Mathalicious, this great way that turns math
from a boring subject for some students into something very interesting.
And we've learned about today a math coach who helps teachers to make their
lessons more interesting with this program.
He devoted himself to math and making it interesting for others.
Well, we still have some more to learn about Mathalicious in our second reading
today.
(Music).
Mathalicious!
For example: Do people with small feet pay more for shoes?
How long must a person exercise to burn off a Big Mac?
Each lesson includes handouts, a teacher's guide and a short multimedia
presentation.
Also, each lesson requires students to use specific math skills included in the
Common Core State Standards.
While the site does offer a handful of free samples, the lessons are based on
payment.
But for many math teachers, the cost is worth it.
Mathalicious gives them the tools they need to turn bored students into inspired
ones!
(Music).
Before the break we talked about open-ended questions, and we have some examples
here. We read:
For example: Do people with small feet pay more for shoes?
How long must a person exercise to burn off a Big Mac?
Well, these are great questions to think about, and they do involve math.
They do! And these are things that you can apply to your everyday life.
They have real-life applications.
And we see this phrase here: burn off.
How long must you exercise to burn off a Big Mac or a hamburger?
And if you burn something off, what does that mean, Gabe?
Well, that means maybe you have some... something on your body or some calories
or fat, and you want to get rid of it.
So often people exercise to burn off fat, to burn off calories.
You get calories by eating.
And especially something like a Big Mac or a hamburger might give you a lot of
calories.
You want to burn those off.
Right. So you want to use all of them up.
You want to exercise and use that energy and burn it off.
Continuing in the article we see:
Each lesson includes handouts, a teacher's guide and a short multimedia
presentation.
So each lesson has many different parts.
It's not just "This is a math problem. Please solve it." It's much more
interesting.
That's right.
You might have a piece of paper, a handout and also a multimedia presentation.
Well, that's kind of a fun word.
"Multi-" is many, and media.
And there are different kinds of media.
You might have a video.
That's a medium.
Or a PowerPoint presentation, that's a kind of media; or some... even pictures
on a slide show.
Even here at Studio Classroom, you might see some pictures in the background.
That's another kind of media.
Well, how do we continue?
We see: Also, each lesson requires students to use specific math skills included
in the Common Core State Standards.
So there are very specific skills that are being taught in these lessons so that
the students are continuing to learn.
That's right.
The Common Core State Standards, something that everybody must match up to.
Well, we continue.
While the site does not... or the site does offer a handful of free samples, the
lessons are based on payment.
So you do need to pay for this wonderful lesson.
Well, it's time for us to learn something new with Liz in the Grammar Gym.
Hello, friends.
I hope you're all doing well today.
My name is Liz, and I want to thank you for joining me here at the Grammar Gym.
In today's article we read:
While the site does offer a handful of free samples, the lessons are based on
payment.
That's our Grammar Tip sentence.
Notice how the sentence begins with the word "while." Normally we use "while" to
talk about how two things are happening at the same time like:
Jim waited in the car while Teresa went to buy coffee.
But in the case of today's sentence, "while" means "although." So we can say:
Although the site does offer a handful of free samples, the lessons are based on
payment.
Let's have a look at some more example sentences.
While cats are generally known to not like water, tigers do enjoy swimming.
Or: While tourists are not allowed to walk into the palace, the palace gardens
are open to the public.
Now it's your turn.
Try making a sentence using "although" at the beginning, and then change it and
practice using "while" instead.
That's it for today.
This is Liz from the Grammar Gym.
See you next time.
So you do have to pay for these lessons.
And in our article we see:
But for many math teachers, the cost is worth it.
Mathalicious gives them the tools they need to turn bored students into inspired
ones!
All right.
Well, let's take a look at that word "inspired." If you are inspired by
something, that means you are interested in it,
maybe even enough to do something or create something on your own.
You are inspired.
And if something is inspired, then it is special and you want to do great
things.
Well, I think that we might be inspired by watching another video and then
joining Michelle in the Language Lab.
When we turn on the TV, how does what we see affect our well-being?
According to University of California psychologist Dr. Keltner, we can measure
this using something called the jen ratio.
Every time we witness something negative, we add one to the denominater.
Every time we witness something positive, we add one to the numerator.
According to Keltner, the higher the ratio, the better off we are.
So if the jen ratio is rael, how much are we really able to control our own
well-being?
And in the face of all this negativity, what can we do to improve not just our
own jen ratio but everyone else's too?
(Music).
(Chinese).
And let's see what our teachers are up to.
We're talking about Mathalicious today.
And I do wonder if you have ever used math outside the classroom.
Carolyn?
I have, and actually it was really fun.
When I was in middle school, I was taking an advanced math class.
And our teacher taught us a trigonometry equation, this really complicated
thing.
But actually, it was very easy and very fun.
We got to go outside and figure out how fast the cars were driving in front of
our school by using this math equation.
So you can use math outside the classroom.
I have also used math outside the classroom.
I went to the market to buy two apples for myself and one for my friend.
I bought three apples.
I used math.
Well, it's time for us to say goodbye.
But we hope to see you next time join us here at Studio Classroom.
See you later.
