There are few things that Ruben likes more than daydreaming. One day, while he's supposed to be finishing some exercises his teacher has assigned him, he starts jotting down a pirate story in his math notebook. Incredibly--and mysteriously--the exercises that he was supposed to be working on disappear. Will he be able to recover them before his teacher gives him a failing grade? This humorous tale will delight kids as they learn about the importance of studying.
