(upbeat music) (soothing music) ♪ It's a great morning ♪ ♪ And we're here learning ♪ ♪ Let's talk about measurements ♪ That's right, today, as you might have guessed from our song we are talking about measurement.

You know there's different types or ways to measure something.

So let's take a look at these objects.

We got different things, right?

We have a pizza pinata, because everyone needs a pizza pinata.

We have some dice, we got different kinds though.

One is made of foam, one is made of wood.

And then we've got a watermelon.

And if I said, "Hey, which of these objects is bigger?"

How would you answer that question?

What does bigger mean?

Well, that's where measurement comes in.

There are different ways that we might consider something to be bigger.

And two that we're going to talk about today are the length of something.

We could also refer to it as the height, if we're talking about how tall something is.

And the weight.

So we're looking at the height and the weight of different things.

And we're going to look at these objects and we're going to measure them.

And these are measurable attributes, okay.

When we're talking about height, we might think of the words short and tall as descriptors of height.

When we're talking about weight, we're thinking is something heavy or is it light?

So, is it easy to carry or is it hard to carry?

And so, what we're going to do is we're going to actually use our tools.

We've got some different tools.

So this is a yardstick.

You may have a ruler that is about a foot long.

Well, this is three feet long, okay.

So we can use this and it will tell us how many inches tall that our objects are.

Now that that's good for the height, but what about the weight?

This isn't going to help me with the weight, so we've got to use something else.

And we have another tool here.

We have a scale.

In fact, we have two different scales.

So if I set an object on top of this, it will tell me the weight of an object.

And this is our other scale.

And it can do things that are a little bit heavier.

So that's why we have that one.

You can even stand on this one.

So, let's figure out which of these objects is bigger.

You know what we need, we need to keep track of this in some way.

Think I need a chalkboard.

Chalkboard!

(hands clapping) (groovy tune) There we go.

Now we're ready.

Okay, so as we look at these objects, let's try and figure it out.

Let's start with our pizza pinata, and then we're going to move to the dice.

Okay, and let's start with the height.

Okay, height means we're seeing how tall something is.

So which tool do I need?

Do I need a scale or do I need a ruler or a yardstick?

I need the yardstick, right?

Okay, so let's start with this and let's go ahead and do our pizza one first.

So if I put it here, I'm starting on the ground.

And on the side it's telling me how many inches tall this is.

And this is about 16 inches, okay.

So let's keep track of that.

16 inches is the height of the pizza.

Okay, but we can measure the other things, right?

So if I'm looking here, I've got my foam dice and my wood dice.

Let's do the wood one, all right.

And that's about four inches tall.

Our foam one is about five inches tall.

So we can track those, right?

Okay, so we said the wood was four inches and the foam one was five.

Now we have the watermelon.

Now the watermelon, if I measure this one, okay.

It is about eight inches tall.

It's pretty close to eight.

And we've got all the heights.

So now that we've kind of tracked that and we're seeing how tall these things are, which one is the tallest?

I can see this in our chart, because now I've been tracking those.

And I know that the pizza pinata is the tallest.

Now I could probably have told you that just by looking at them, right?

But if I wanted to know by how much, I need specific measurements.

And that's where these come in and are really helpful.

Now, remember our question was, what is the bigger object?

Well, according to height, it's the pizza pinata.

The smallest object is our wood dice, but let's move to weight.

Now, as we go to weight, we can use our scale.

And I'm going to start with, what do you think is the heaviest object?

Maybe it's the one, that's the tallest.

We said, this was the tallest.

Well, if I measure this on my scale.

I got to turn it on first, as I measure it.

Well, it only reads that it is, oh, it's only one pound.

Okay, so one pound and I can track that.

And I can do this for each object.

And as I do it, here's my foam dice.

Well, it's only half a pound.

Oh, half a pound.

So that's not even a full pound.

My wood dice.

If I set that on here, it is also a pound.

So it's about the same as the pizza.

And then my watermelon.

Now I think this is pretty heavy, so I'm going to use the bigger scale.

And as I set it on.

It's 12 pounds.

12 pounds for the watermelon.

So look at that.

So what is bigger?

Well, it depends on what we're measuring.

Are we measuring weight?

Are we measuring height?

Now that you know how to measure these things, you can grab a scale, a ruler, and measure things around your home too.
