Compare & Order Numbers

Poll

How many pounds do you think the largest alligator ever caught weighed?

142 pounds

859 pounds

1,012 pounds

1,429 pounds

The correct answer is..... 1,012 pounds!!!! That's half a ton or about 100 bowling balls.

Since we just learned to round, let's go to the next slide and round that number.

Multiple Choice

What is 1,012 rounded to the nearest thousand?

2,000

1,100

1,000

...now back to comparing numbers.

Why is it important to know if a number is greater than or less than another?
What symbols do we use to compare numbers?

Poll

Which does not belong with the comparison symbols?

If you said +, you are correct! The comparison symbols are >, <, and =.

A fun and easy way to remember these symbols is to pretend they are an alligator's mouth. An alligator (especially the ginormous one we talked about earlier) loves to eat. They want to eat AS MUCH AS POSSIBLE!!
To model this, you would have the alligator's mouth eating the larger number. EX: 54 > 29
***This is a great way to remember which way the symbol goes, BUT, we do NOT say anything about an alligator when reading our comparisons. We always use correct mathematical language and use "greater than", "less than", or "equal to". :)

Multiple Choice
