We use our home - and I do have a business that I run from home that sells and supplies educational things to make learning fun. And its building into a resource centre too - so I am happy to share ideas etc.
We are very blessed - we have a big garden, with a pool, space for a trampoline and a club house. I have a space the size of a double garage that is dedicated as a learning space and it is split into a reading corner, art corner, science/maths corner and a pretend play area (wooden toys, dress up clothes etc. Tables and chairs in the middle of the room, and things like lego, mechanno etc packed into plastic stackable crates. We have trees to climb and space for riding bikes and playing hopscotch.
We use our lounge for courses requiring presentations and we use the kitchen for cooking courses we run.
We do often spill over to the parks in the neighbourhood as well as sometimes other parents' homes.
We make it work I guess.
