00:00Compare two-digit numbers
00:06In this lesson, we will learn how to...
00:09Compare two-digit numbers
00:12Let's start learning about the comparison symbols for greater than, less than, and equal to.
00:19Look, we use the mouth of an alligator to represent the symbols.
00:24His mouth is always open to the larger number.
00:27Let's see.
00:29Let's compare two numbers, 32 and 14.
00:33When comparing two-digit numbers, we will compare the 10s first.
00:37If the 10s are the same, then we compare the 1s.
00:41We represent these two numbers in 10s and 1s like this.
00:45If we look at the 10s, 3 is greater than 1, so we can then say that 32 is greater than 14.
00:54We can also use the symbol to show this.
00:57The alligator's mouth opens to the larger number like this.
01:01It shows that 32 is greater than 14.
01:05Or, 14 is smaller than 32.
01:09This time, we are comparing 21 and 26.
01:14Let's compare the 10s first.
01:17Oh, the 10s are the same.
01:20Then we look at the 1s.
01:221 is less than 6.
01:25Therefore, 21 is less than 26.
01:29Now, the alligator's mouth opens to the larger number like this.
01:34It shows that 21 is less than 26.
01:38Or, 26 is greater than 21.
01:42Now, let's see another example.
01:45Can you compare these two numbers?
01:47When comparing the 10s, we find that they are the same, 5 and 5.
01:53Now, look at the 1s.
01:56OK, the 1s are also the same, 8 and 8.
02:01Thus, we can say that 58 is equal to 58.
02:06This time, the alligator does not know which number to eat, so his mouth looks like this.
02:13It means that 58 is equal to 58.
02:18Ready? Let's practice.
