The three little pigs

I read the three little pigs, Usborne first reading, level 3 book.
Three little pig's mother thought that their house was too small to live with.
So they decided to build new houses.
First pig built a house made of straws.
Second pig built a house of trees.
Third pig built a house of blocks.
One day a wolf look for the houses...
What will they do?

This is one of the very famous story in Japan.
And it was very interesting to read.
It was good that they beat the wolf finally.
I think that the third pig was very smart to build house of blocks.
