What are three main components?

A system is like a toy box, it has parts that work together to make something fun happen.

1. Blocks are like the pieces you build with. In a system, they’re called components. Just like blocks help you make towers or cars, components help a system do its job.
2. Glue is what holds the blocks together. In a system, that’s like connections, things that let parts talk to each other and work as one.
3. Rules are how you know which block goes where. In a system, they’re called controls, kind of like instructions or switches that tell everything when to move or stop.

Together, these three main parts, components, connections, and controls, make sure your toy box (or any system) works just right! A system is like a toy box, it has parts that work together to make something fun happen.
