What is modelling?

Modelling is when we take something big or complicated and make it into a smaller version that’s easier to understand.

Imagine you have a giant chocolate bar, it's too big to eat all at once. So, you break it into little pieces, like squares or rectangles. Each piece is still part of the whole chocolate bar, but now it’s easier to count and see how much you’re eating. That’s kind of what modelling is like in real life, we take something big or hard to understand and turn it into a simpler version that shows us how things work.

Think about building a tower with blocks. You might not have the actual tower in front of you, but you use blocks to show what the tower looks like. Each block is part of the whole picture, just like models help us see parts of something big without having to look at the whole thing all at once.

So whether it's a chocolate bar or a building, modelling helps us understand things by breaking them down into smaller pieces we can handle and play with.
