Line up 5 buckets with water in them (first bucket close and the fifth bucket would be farthest). Mark a start line about ten feet away (or closer for pre-schoolers). Each player stands at the start line and tosses a small ball into the buckets of water starting with the closest. The ball must land in the buckets in numerical order (first bucket, second bucket etc.) If a ball lands in a bucket out of numerical order then the child's turn is over. The child who tosses the ball into the buckets in order wins!
