## Alligator Eats the BIG Number

Antoinette Mia Pettis

Hi! My name is Ivan and I am 12 years old! I like numbers; do you?

My little brother DeSean, who is 5, does not like numbers. He doesn’t know how to compare numbers. Can you help him?

DeSean really likes Alligators! So I was thinking we could use Alligators to help him compare numbers.

< This is the less than sign.

> This is the greater than sign.

= This is the equal to sign.

See how the < and > look like an Alligator’s mouth?

The Alligator’s mouth needs to eat the big number. For example:

3 < 9

See how the sign faces the BIG NUMBER.

To help us remember which way the signs face we will use the saying “Alligator eats the BIG NUMBER!”

If the numbers are the same we use the = sign. For example:

5=5

Let’s do a few problems together to see if you and DeSean understand.

2 ___ 8

Which sign do we use?

2 < 8

Right! We do use the Less than sign because the Alligator eats the BIG NUMBER!

9 ____ 1

What do we use now?

9 > 1

Yes! You got it. We use the greater than sign because…the Alligator eats the BIG NUMBER!

6 ____ 6

6 = 6

Great job. We use the equal to sign because the numbers are the SAME.

I think DeSean understands comparisons now. Thank you so much for helping!
