Think about a giraffe’s neck. It’s really long because it helps the giraffe reach the tall trees to eat leaves. When we say something is ‘long’, it’s like that neck - it stretches out and goes a long way. Maybe you have a toy train track that goes across the whole room. That track is long because it takes a while to get from one end to the other.

Picture a big piece of string. If you stretch it out from your hand to your friend’s hand, and it keeps going and going, that’s long. It’s like when you draw a line across a big piece of paper, and the line goes from one side to the other without stopping. That’s a long line!

Think of a caterpillar crawling on a leaf. It takes a long time to get across because the leaf is long. Just like when you walk down a long hallway, it feels like it takes forever to reach the end. So, ‘long’ is when something takes up a lot of space from start to finish, like the caterpillar’s journey across the leaf.
