Visual comparison means looking at two or more things and seeing how they are different or similar by using your eyes.
Let's pretend you have two toys in front of you, one is a red ball and the other is a blue block. You can visually compare them by looking at their color, shape, size, and texture. You notice that the red ball is round and the blue block is rectangular. You also notice that the red ball is smaller than the blue block. That's visual comparison!
When you are older, you might use visual comparison to compare things like graphs, photos or charts. For example, you might compare two graphs to see which has more information, or you might compare two different photos to see how they are similar or different.
Visual comparison is an important skill that helps you understand and analyze the world around you.
