- Good morning, everyone!

It's so good to be with you today.

I have been out getting some pizza for the teachers.

We're all gonna have pizza for lunch today and it smells so good!

(Frisbee muttering) Oh, Frisbee, thank you!

Frisbee brought my postcard.

Thank you.

- You're welcome.

- Okay, let's see what it says.

Miss Post, I need you to decide which of my siblings won our pizza eating contest.

We're all about pizza today.

I ate half of my pizza, my sister ate four-sixths of her pizza, my brother ate two-fourths of his pizza.

How fun!

It sounds like you have a really fun group of siblings at home.

So I get to help decide who the pizza champion is.

And I know just the math we need to do it.

- Fine!

I can take a hint.

I've got a bunch of math homework I need to go eat anyway.

(giggling) - Bye, Frisbee.

Okay, to make sure that everyone watching can picture just how much pizza you ate, I think we should cut these fresh pizzas, just like you described.

So let's say that you each had a large pizza for this contest.

I'll determine who the champion will be by comparing the amount of pizza that each of you ate.

So we'll see who ate the most, who ate the least, and were there any equal amounts?

Okay, let's pause and talk about fractions for just a minute.

I love to think of fractions just like the parts of a pizza.

So the top number or the numerator is the number of slices that were eaten, and the bottom number or the denominator is the number of ways that the pizza was sliced, it's how many slices you started with.

Okay, so you said that you ate half of your large pizza.

That means that the pizza was only sliced into two parts initially, and you ate one of those parts.

So we will cut this pizza into two slices, and then we'll show that you ate one of those slices.

Woo, it smells good!

Then you said that your sister ate four-sixths of her pizza, so that means that the pizza was sliced into six pieces and she ate four of those pieces.

So we're gonna cut this pizza just like you described.

And then last, you said that your brother ate two fourths of his pizza.

So that means that the pizza was sliced into four pieces, and your brother ate two of those four pieces.

So we'll cut this pizza just like that.

Now, let's compare.

I love this, this is such a great way for us to compare fractions.

And what we can see is that one half and two fourths are really the very same.

It also shows that your sister, who ate four-sixths of her pizza, definitely ate the most.

So you could write that as an inequality, which means one number is greater than, or lesser than the other number.

So in this case, your sister's four-sixth of a pizza was greater than the one half.

So be a good sport, tell your sister congratulations.

I had so much fun with you today.

I hope today's lesson helped you think about how you can picture fractions like slices of pizza.

Now, remember the numerator, that top number, is how many slices were eaten, and the denominator, the bottom number, is how many slices the pizza started with.

It's like your total that you start with.

Being able to picture your math problems is such an important skill.

I hope you have a great rest of the day.

I don't know about you, but I think I'm gonna have this pizza for lunch.

Remember, keep a positive mindset, grow every day by reading and asking questions.

And remember, there's nothing that you can't do if you put your mind to it.

I'll see you soon!

Frisbee!
