Visible Thinking involves several practices and resources. Teachers are invited to use with their students a number of "thinking routines" -- simple protocols for exploring ideas -- around whatever topics are important, say fractions arithmetic, the Industrial Revolution, World War II, the meaning of a poem, the nature of democracy. Visible Thinking includes attention to four "thinking ideals" -- understanding, truth, fairness, and creativity.
