What are borders?

Borders are lines that show where one place ends and another begins.

Imagine you have a big cookie, and you want to share it with your friend. You use a knife to cut it in half, now each of you has your own piece, and the line where the knife went is like a border between two parts. That’s how borders work on maps or between countries.

Think about your favorite toy, maybe a teddy bear or a bicycle. If you put it in your room, there's usually a door that leads to the hallway. That door is like a border too! It shows where one place (your room) stops and another (the hallway) starts.

Sometimes, borders are like a fence around your yard, they help people know where they are and who lives nearby.

Just like you might move your toy from one room to another, borders can change too. Countries sometimes agree to redraw their lines on the map, just like you might decide to make a new play area in your room!
