Number Neighbors

Lesson Plan - Get It!

Audio:

• Do you know the neighbors on your block?
• What about friends who live on your street?

Sometimes, numbers can be like neighbors! Check out this number.

5,723

The numbers 5, 7, 2, and 3 are called digits, each living in a certain place.

• The 5 lives in the thousands place
• The 7 lives in the hundreds place
• The 2 lives in the tens place
• The 3 lives in the ones place

Hopefully, they all get along!

Like good neighbors, understanding their places helps you know how big the number is!

• But what if you need an even bigger number, like in the millions?

Here's a number like that.

7,768,000

That's about how many different animals there are in the world!

For bigger numbers, you need extra places for the digits to live.

• a one millionth place
• a hundred thousands place
• a ten thousands place

Another way to show big numbers like this is in extended form. Check this out.

2,346 lollipops

Wow, that's a lot! But you can break it down like this.

2,346 = 2000 + 300 + 40 + 6

I's the same amount but stretched out, which is why it's called extended form.

Here's how a really big one looks.

8,231,572 = 8,000,000 (That's 8 million!) + 200,000 + 30,000 + 1,000 + 500 + 70 + 2

Phew! That was a long one.

Great job breaking it down!
