Closed map

Do you know what a map is? It's like a picture that shows you how to get from one place to another. But sometimes, when we look at a map, we don't want to see every little detail. That's where a closed map comes in.

A closed map is like a special kind of map that only shows you the important parts. It's like if you wanted to draw a picture of your family, but you only drew the people and not the background.

Another way to think about a closed map is that it "fits everything inside." Imagine you have a box and you want to put some toys inside. You can't leave any of the toys outside the box - they all have to fit inside. A closed map works the same way. It takes all the things you want to show (like roads, buildings, and landmarks) and makes sure they all fit on the map.

So, when we talk about a closed map, we mean a map that shows only the important things and fits everything inside. It's like a simplified version of a regular map, but it still gets us where we need to go.
