Top picture book author and artist Keith Baker presents a classic book about problem solving for the very young.
One day Ant encounters a great big ball of string, and can't see his way over or through it. Fortunately, when he asks his friend Bird "How long is a string?" Bird wisely shows him all the wonderful ways a string can be cut up and used, to the delight of both friends. And after a day of adventure the question doesn't seem to be a problem anymore -- a string can be as long as Ant needs it to be.
