Sam’s things are in a heap. Time to tidy up! He starts to organize his things, but quickly runs into trouble. He can make a pile of black and white things. But the penguin also belongs in the things with wings pile. He can make a pile of rocks. But the round rock also belongs in the round things pile. How will he ever sort his 100 things? Marthe Jocelyn takes a fun look at categories and counting in this very cleverly conceived story. Kids will delight in the cut-paper images of everything from a zipper pull to a robot, and Sam’s surprising solution makes for a tidy end to this unique story.
