From Talking Math With Your Kids
"Which One Doesn't Belong?" are thought-provoking puzzles designed to sharpen skills in analysis, argument and divergent thinking.
Created by Christopher Danielson and collected in his book, Which One Doesn't Belong - A Shapes Book, WODB sets help students improve their understanding of math by requiring specific and clear language when delineating how each item differs from the others.
