What are dynamic representations?

Dynamic representations are ways to show things that can change or move, just like how a toy car moves on a track.

Imagine you have a box full of different colored marbles. If I ask you, "How many red marbles are there?" and you count them every time, that's one way to know. But if the marbles keep moving around, maybe they're inside a shaking jar, it’s harder to count them each time.

That’s where dynamic representations come in. They’re like a window into the box that shows you how many red marbles are there right now, even when things are moving. It's not counting every single marble each time, it's showing you the result as it changes, just like a digital counter on a game show.

Think of a living picture, not a still photo, but something that moves and updates itself. A dynamic representation is like that living picture. It shows you how things are changing in real time, without you having to do all the counting or figuring out yourself. It’s as if the box had its own little helper who tells you the number of red marbles every second, no matter how much shaking happens inside!
