This weekend is National Girl Scout Cookie Weekend, but it's not just about the delicious cookies.
The CEO of Girl Scouts in Southern Arizona says the reason the teach the girls to sell cookies is so they can learn integral business skills. That includes math.
One girl scout troop leader says, "all the girls' math skills have just been exponentially amazing."
