Once upon a time, three little pigs left home to make their way in the world. The first pig quickly built a house from straw.

That night, a wolf knocked on the first pig’s door and asked to enter. “Nope! Go away,” said the first pig. “Well then,” replied the wolf, “I’ll huff and puff, and I will blow your house down!” The wolf did just that. The first pig ran away and went to live with his brother.

The next night, the wolf knocked on the second pig’s door. This pig had quickly built his house from twigs. “May I come in?” asked the wolf. “Nope! Go away,” said the first and second pigs. “Well then,” replied the wolf, “I’ll huff and puff, and I will blow your house down!” The wolf did just that. The first and second pigs ran away and went to live with their brother.

The following night, the wolf knocked on the third pig’s door. The third pig had carefully and slowly built his house from bricks. “May I come in?” asked the wolf. “Nope! Go away,” said the first, second, and third pigs in unison. “Well then,” replied the wolf, “I’ll huff and puff, and I will blow your house down!” The wolf huffed and puffed, took a breath, and then huffed and puffed again. Nothing. The bricks held, and the three little pig were left in peace to enjoy their dinner

Each time the wolf knocks, the pigs say no.
Each time the wolf blows down a house, there is one less place for the pigs to run.
Each time the wolf blows down the house, there are fewer pigs left alive.
