Once upon a time, there was a mysterious box. It was big and blue. A little girl named Lucy found the box in her room. She was very curious about what was inside.
Lucy opened the box and saw many colorful things. She saw toys, books, and some math cards. Lucy wanted to sort the things in the box. She put the toys in one corner, the books in another corner, and the math cards in the last corner.
As Lucy was sorting, a little toy bear started to talk. The bear said, "Hello! I am your new friend, Teddy. I can help you with your math." Lucy was very surprised and happy. She and Teddy played with the math cards together, and they had lots of fun.
