 Oh, no. Rainbow Bear, you look confused. You need some help? Yeah, I just need help figuring out what these symbols mean. Oh, well, each of these symbols have names. This one means less and. Okay. An easy way I remember is, the symbol shape looks like an L. Oh, okay, less than, got it. Well, what does this symbol facing the other way mean? Now that symbol's name is the opposite. It means greater than. Oh, less than greater than, okay. I know the names, but what do these mean? Less than what? Greater than what? Good question. These symbols help us find bigger numbers in a number sentence, like this one. See this plate has six dinosaurs and this one has two dinosaurs. So, what number is bigger? The two or the six? Well, that's easy. Six. Exactly. So, the six is greater than the two. We write this greater than symbol in the middle. Oh, six is greater than two. Uh-huh. Well, that's so simple. Great, let's try this one. How about this new number sentence? Okay. This plate has two dinosaurs and this plate has six dinosaurs. You can't trick me, turtle. Six is still greater than two. Well, not so fast. We have to read our number sentence from left to right. The two comes first, so we use our less than symbol. Now we say two is less than six. Always read the number sentence from left to right. There is a less than symbol and a greater than symbol. Oh, so far so good. You want a cool little trick to help you remember the symbols? I love tricks, what is it? Oh, well both the less than symbol and the greater than symbols look like open mouths. Like maybe an alligator's open mouth. They do, look at that, they look like alligator's mouths. Yeah, alligators open their mouths when they're hungry. Since they are so hungry, they always want to eat the bigger number. Oh, okay. The open part of the greater than or less than sign always faces the bigger number. Well, that makes things a lot easier. So if I have this problem, this plate has eight dinosaurs and this plate has four dinosaurs. The mouth will open towards the eight like this. Eight is greater than four. Yup, great job, Rainbow Bear. One less thing though. We have one more symbol and it looks like this. It's called equal to. We use equal to when both numbers are equal or the same. Five is equal to five. Both numbers are the same. Woop, congratulations, Rainbow Bear. Thank you. Now you know the less than sign. Yup. The greater than sign. Yup, yup. And the equal to sign. Yup, yup, yup. Yeah. Man, I'm hungry. You want to get something to eat? Yeah, I'm going to go make a salad. Bop, bop, bop, bop, bop, bop, bop, bop, salad. Why would anybody make a salad when there's all these sandwiches you can make?
