Stand colorful foam pool noodles in gallon buckets weighted with sand (or soil or stones) and set up in a zigzag pattern. Fill a wagon with small water balloons. Kids must pull the wagon around the outside of each bucket without spilling any balloons.
all for the boys- finally a blogger who has crafts & activities JUST for boys!! and she has a little icon that shows how many minutes of bliss different activities give you. (i'm sure my girls will like it too)
