Compare these numbers. Nine, three, and eight. The smallest number is what? The greatest number is what? Order the numbers from smallest to greatest.

In this question, we’re being asked to compare three numbers together. They’re the numbers nine, three, and eight. We know that we need to compare the numbers together because we’re asked to find the smallest number. And then, we’re asked to find the greatest number. To help us find which number is the smallest, let’s model each of our three numbers. Perhaps, we could use cubes. Let’s start with the number nine. One, two, three, four, five, six, seven, eight, nine, a tower of nine counters. Our second number is three. One, two, three. This tower isn’t as tall as the first one, isn’t it? Our third number that we need to compare is the number eight. One, two, three, four, five, six, seven, eight.

Now, by modeling numbers like this, it’s going to help us to compare them. Our first sentence says the smallest number is what? Which of our three towers of cubes is the smallest? Well, we can see that our tower of three cubes is a lot smaller than number nine and eight. This means we can say the smallest number is three. Now, which of our three numbers is the greatest? The word greatest is another way of saying largest. Which of our three numbers is more than the other two? Well, again, if we look at our towers of cubes, we can see that our tower of nine cubes is the tallest. This must mean it contained most cubes. The greatest of our three numbers is the number nine.

Now that we’ve compared our numbers and we know what the smallest and the greatest numbers are, we can order them from smallest to greatest. We said the smallest number was the number three. The greatest number was the number nine. And this means that the number eight must be in the middle. We know this is true because if we put our towers of cubes in this order, we can see that they now go up in size from the shortest to the tallest. Out of the numbers nine, three, and eight, we found that the smallest number is three. The greatest number is nine. And in order from smallest to greatest, the numbers are three, eight, and nine.
