• how do we know that which number is more than, less than, same as? is it the same with the fractions?

• For example: if the question is...
444 _ 555 look at the first number it is 4, 4 comes after five, so 555 > 444!

• Instead of counting one by one, can we count by 2's,5's, and 10's so it would not take too long to count?

• If the number is small, like 10, you could count by 1s or 2s or 5s...if it's a big number, like 100, you'd want to use 10s or somehting like that. It really depends on the number.

• Is counting numbers is same thing as natural numbers?

• Question: Is counting numbers the same as counting natural numbers?
The word number has a very broad definition. A number could be 0,1,2,3, 3.55, 4, 100, 101 .11 and so forth..its just a numerical value.

A natural number is more specific than just a number, but is very similar to just a number. Natural numbers by definition are considered positive integers (whole numbers not fractions or decimals) like 1,2,3,4,5, 100, 1000.

## Video transcript

Voiceover:Gavin has these horses. Is the number of horses in each picture below more than, less than, or same as the number of horses Gavin has? Let's first look at how many horses Gavin has. He has one, two, three, four, five, six horses. Let's remember that and let's compare each of these amounts of horses to the six horses that Gavin has. Let's look over here, over here we have one, two, three, four, five, six horses. This is the same number that Gavin has, they're just arranged differently. This is the same, we'll put in the Same as bucket. Now, here we have one, two, three, four five horses. This is less than the six horses that Gavin has, five is less than six. Here and I can just look at this and see that there's more than six but we can count them. We have one, two, three, four, five, and then another five that's going to be 10. Or we can say one, two, three, four, five, six, seven, eight, nine, 10. Well 10 is more than six, 10 is more than six, so we'll put it in the More than bucket. Now here we have four and four well that's going to be eight. One, two, three, four, five, six, seven, eight. It's again, that is more than the six up here. That's more than six and then here we have one, two, three, four horses. Well four is less than six, so I will put that, I will put that in the less than, in the Less than bucket just like that. Let's check our answer to see how we did. We got it right.
