Simple tactical exercises would probably work well.
Present simple situtations where the best situations isn't presented as one of the obvious options. Make survival the clear goal rather than the death of the enemy.
I went through one kind of like this:
"Your in a room with a wooden door to the north and a wooden door to the south. You can hear, through the small gap at the base of the door, something large moving in the room to north. You do not hear anything to the south. The room you are in is lit by an oil lamp. There is a hand mirror by the lamp. Two cabinets are against the east wall. One contains a collection of weapons: a long sword, a shield, a spear, a mace, a strung short bown, a quiver of arrows, a dagger, and a great sword. The other contains common clothing items for men and women. The west wall is lined with the remains of furniture."
The goal is to survive so a smart person will try to figure out what's outside of the room. Using the hand mirror you can check under the doors to get an idea of what's beyond.
Basically everything else is described in an effort to dislead the person though because if you leave out of the south door, you get safety to town. That's the win condition. Choosing to retreat from obvious danger is the less, using any of the other props is a matter of degrees.
