Definition: A division into smaller pieces of something that has already been divided.
Alright class, settle down, let’s take a look! That dictionary definition is pretty clever, you see – it really gets to the heart of what ‘subdivision’ means for you and me. Think of it like this: imagine you've got a big chocolate bar, right? (Raises hand enthusiastically) You break it into squares - that's one division! But then, you decide to split each square in half again – now you have even smaller pieces! That’s subdivision. It’s taking something already divided and making it even more broken down. It's like building with LEGOs – you start with a big baseplate, then you subdivide it into sections for your house, then even smaller blocks for the furniture. So, 'subdivision' simply means dividing something further than it already is. It’s about taking a piece that’s already been broken up and making those pieces even tinier. Does that make sense? Any questions before we move on to our next example?
