Marthe Jocelyn is back with another clever concept book to follow Hannah's Collections, Ones and Twos and Where Do You Look? This time, she tackles counting and categories.

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.
