Have you said "You're a great helper!" to a child today?
Walk the Plank
2"x4"x8' boards
blindfold
flags
For older children: Lay the boards out end to end in a zig zag pattern (usually 3 boards). Place the mask on the child. Place a bucket of flags (can be handkercheifs) at the end of the planks. The object is to go from one end of the planks to the next (blindfolded), and bring back a flag in the shortest amount of time. Each time the player steps off - they need to go back to the start. For younger players: Lay out the boards in more of a straight pattern. Don't use the blindfold - and make the object to go from one end, grab a flag and make it back. They shouldn't be timed.
Optional for both ages: you can also set up two courses and make teams!
