We did a cracking exercise to show appreciation of dead ground, judging distances, translating from what you see to a map, one was being sat on a high point during a walk and having to lay out what you see in front of you within set arcs( say 30 degrees and out to a prominent feature) without a map, then compare to map once done, the other was to walk a route then draw it to scale to practise pacing, taking bearings to mark position, route planning, both models can be 3D. The winner gets a steak dinner at the Savoy and a night of dancing at the RAC club!
