One day, a boy named Tim went to the gym with his dad. The gym was a big room with lots of fun things to play with. Tim saw a big ball and ran to it. He wanted to play with the ball but he was a bit careless.
Tim tried to pick up the big ball, but it was too big. He tried to squeeze it with his hands, but it was too hard. Tim said, "Dad, I can't pick up the ball. Can you help me?"
Dad came over and said, "Tim, you have to be careful in the gym. Let's play with a smaller ball." Dad gave Tim a small ball that was easy to squeeze. Tim and his dad played together and had lots of fun in the gym.
