Once upon a time, in a small town, there was a big machine. The machine was very tired. It worked all day and all night. The machine had a job to do. It had to fit big blocks into small holes.
One day, a little boy named Tim came to see the machine. He wanted to help the tired machine. He tried to fit the big blocks into the small holes, but they would not go in. Tim thought and thought. Then, he had an idea!
Tim tried to fit the big blocks into big holes. And guess what? They fit! The machine was not tired anymore. It could work better now. Tim and the machine were happy. They had found a new way to fit the blocks and the machine could rest.
