Wide Awake Jake by Rachel Elliot tells the story of a little boy who has a hard time falling asleep. To help him go to bed, his mother encourages him to pretend to be an animal (such as a bird, a mouse, and a bear). Each time, he ends up becoming scared and has to go back downstairs to his mom. It isn't until his mom tucks him in that he's finally able to calm down and fall asleep.
I thought this book was cute, but I definitely think it should be reserved for younger elementary students. Kindergarten and first grade would probably enjoy reading this book more than second or third grade and up. I thought the illustrations were well done, and the book included a lot of different onomatopoeias that young children will enjoy hearing.
A fun way to incorporate an activity with this book would be to let children act out the animals as we read the book. I think it could be a fun way for students to learn more about the animals, and I also think they would enjoy having the chance to get up from where they're sitting in order to pretend to be the animals that we read about.
