Which One Doesnt Belong?: A Shapes Book by Christopher DanielsonWhich One Doesn’t Belong? has won the Mathical Book Prize, which will be presented to Christopher Danielson at the National Math Festival in Washington, DC on April 22, 2017. The Mathical Book Prize is an annual award for fiction and nonfiction books that inspire children of all ages to see math in the world around them.
Every colorful page of Christopher Danielson’s children’s picture book, Which One Doesn’t Belong?, contains a thoughtfully designed set of four shapes. Each of the shapes can be a correct answer to the question “Which one doesn’t belong?” Because all their answers are right answers, students naturally shift their focus to justifications and arguments based on the shapes’ geometric properties.
In the companion teacher’s guide,(978-1-62531-081-1) Danielson shows how to facilitate rich discussions and teach mathematical argumentation using Which One Doesn’t Belong? He models how to listen closely and respectfully to students’ ideas about shapes. Danielson synthesizes research about how children learn geometry, discusses the role of geometry in the mathematics curriculum, and gives plenty of practical advice about different ways to implement Which One Doesn’t Belong? in classrooms. He also discusses the mathematical ideas likely to emerge on each page and—drawing from his direct experience using Which One Doesn’t Belong? at several different grade levels—helps teachers anticipate and think about students’ likely answers.
Most curricula treat geometry as little more than vocabulary lessons. Which One Doesn’t Belong? and its accompanying guide are powerful, flexible resources teachers can use to provoke lively discussions and deep learning about shapes with students of all ages.
"The Cardinal" on Imus - July 13 2006
Which One Doesn’t Belong?
Bernard McGuirk, the executive producer of Imus in the Morning, did and may still do a bit in which he played Cardinal Egan and would ridicule Don Imus up one side and down the other in a thick Irish accent. Imus was always wrong because Egan had a witty and sometimes degrading reason for which one actually did not belong. The winner the funniest will receive a copy of the book. Like Like. Wolterstorff is clearly the one who does not belong, because he has more than four letters in his last name.
A "Which One Doesn't Belong" routine encourages students to reason about the similarities and differences among a set of numbers, expressions, shapes, or images.
