Use the greater than and less than signs to compare numbers. When we compare numbers, we're telling about their sizes. Three is greater than one. 2 is less than 9. Instead of writing in words, we use signs that tell about size. Math signs are quicker, tidier, and they're recognized around the world. Have you seen this before? This sign means greater than. We use it to show that one value is greater than another. So we could write four is greater than two. We know this statement is true. Four is more than two. This sign faces the opposite way. It is the less than sign. We could use it to write five is less than 10. Right about now, you might be thinking, "How can tell those signs apart?" I'll explain the sign, and you're going to get it very quickly. We understand the sign from left side to right side, like reading word on page. On the left, see two points, and on the right, there's one point. 2 is greater than 1. This is the greater than sign. I'll use it again. 6 is greater than three. This sign faces the other way. Again, go left to right. On the left, there's one point. And on the right, there are two points. One is less than two. This is the less than sign. Here's another example. Five is less than 10. You can use this thinking to get it right every single time. Watch this. Which sign do we use with these numbers? Well, put two points beside the bigger number and one beside the smaller number. Join the dots and we've instantly got the correct sign. This statement reads 2 is less than 8. Another one. Put two points beside the bigger number, one beside the smaller number. Join the dots. This statement reads 11 is greater than seven. You can see writing the sign is easy. Reading it off takes bit more practice. In time, these new signs will become familiar just like these signs. For now, think the best approach is to just get started with this easy logical thinking. And if your teacher gives you pair of numbers like this, then you use sign you already know. Now, it's time for you to use the greater than and less than signs for yourself in your math book. And while you're practicing, you'll be building your math muscle.
