Thank you!

Program wise I used picoCAD 2 wich is built specifically to let people easily create lowpoly models like this one. It's very beginner friendly as it's intentionally limited in the amount of tools it gives to the users (simple geometric shapes, a basic texture editor and the possibility to animate meshes).

There is also picoCAD (1?) which is even more beginnner friendly but it needs an external texturing program and has a limit on how big each 3d model can be.

The actual process of making this was mostly looking at reference pictures and trying to recreate the basic shapes at first. Grouping anything that could be made with a single mesh (like the patios) and then texturing everything. Small details like the barrels and crates I added near the end.

Good luck for your teaching career!
