Pushes students to start predicting measurements from the beginning of the book. Students are actively modifying previous predictions and generating new ones as the story is read. This book would be suitable for kindergarten through fifth. Students in kindergarten could compare the animals in the book by putting them order them based on weight after the read aloud. This book could be used as an introduction for a "Stay Afloat" lesson, using a balance scale and base ten cubes to measure objects in the students' pencils boxes. Fifth grade students could apply the concept of sinking the boat to capacity. Students could transform the weight of the animals into specified units of water, and fill the boat with water until it has "sunk" (filled).
