Ordering: Tallest, Longest, and Shortest

In this video, we will learn how to directly compare more than two objects by length or height using the words tallest, longest, and shortest.

When we compare height, we can use the words tallest or shortest. When we compare the length of objects, we can use the words longest or shortest. This snake is longer than the other two snakes. And this snake is shorter. Let’s practice comparing objects by length or height using the words tallest, longest, and shortest.

Which is the tallest? Is it the mouse, the giraffe, or the dog?

Let’s compare the heights of the animals. This is the height of the mouse, the giraffe, and the dog. The giraffe is taller than the mouse. The giraffe is also taller than the dog. So the giraffe is the tallest animal.

Which animal is the shortest? Is it the cat, the zebra, or the skunk?

The cat is shorter than the zebra, so is the skunk. The skunk is also shorter than the cat. If the skunk is shorter than the zebra and the cat, then the shortest animal must be the skunk. This animal is the shortest.

Which is the longest? Is it the school bus, the paper clip, or the carrot?

We need to compare the lengths of these objects to find the longest. This is the length of the school bus, and this is the length of the paper clip. This is the length of the carrot. The carrot is longer than the paper clip. The school bus is longer than the paper clip and the carrot. If the school bus is longer than the paper clip and the carrot, then it’s the longest. So the school bus is the longest.

What have we learned in this video? We’ve learned how to compare height and length using the words tallest, longest, and shortest.
