This Activity is meant for Boy Scouts, Webelos scouts.
Decide for yourself if it is appropriate for your younger scouts or not.

100 sheets of paper
A pencil and couple extra papers to write on.
Some reward for the player or patrol that reaches the end first.

Create a grid of paper at least 6 sheets by 6 sheets - the bigger the grid, the longer it takes.

Place the sheets of paper in a grid on the floor.
On a sheet of paper, draw a 10x10 grid and on that grid draw this maze:

X X X X X X X X X X X X
X X X X X X X X X X X X
X X X . . . X X X X X X
X X X . X . X X . . . .
. . . . X . X X . X X X
X X X X X . X X . . . X
X X X X X . . X X X . X
X X X X X X . X X X . X
X X X X X X . . . . . X
X X X X X X X X X X X X

The dots indicate free spaces and the Xs indicate mines.
Have all scouts gather at the left side of the grid.
The first scout steps on any paper he chooses.
Compare where he steps with your master sheet. If it is a mine he is blown up, if it is open, he takes another step.
Continue until he hits a mine, then next scout gets to go.

This builds on each scout remembering previous correct moves and adding another until someone finally reaches the end and the reward.

Once a maze is done, if they want to go again, just draw a new one on your master sheet and start anew.
