The board is marked with lines twelve inches from each end.
Children start and finish behind the lines at opposite ends.
When they switch they travel to the mark on the opposite end of the board before starting back to their original positions. Each child travels to the opposite end of the board and then back without falling off or touching any body part to the ground. There is no limit to the number of attempts or time allowed to complete this challenge. The two youngsters use each other for balance to switch places or travel to the opposite end of the board without falling off the board or without touching the ground with any body part. Children start the entire task over if any body part touches the ground.
