“Eliminate all other factors, and the one which remains must be the truth,” Sherlock Holmes has said about his method of detective work. In Sylvan Dell’s new picture book, Deductive Detective, our hero Detective Duck shows that he’s learned from the best! He dons his best deerstalker hat, his much-too-big magnifying glass, and solves the case of the missing cake with the same methods the pros use!
That is, a style of logical thinking called “deductive reasoning.” In deductive reasoning, someone finds an answer they’re looking for by first finding out what the answer isn’t. When Detective Duck examines the clues and finds out which of his friends couldn’t have stolen the cake, it leads him closer to what really happened!
Of course, you don’t need a weird hat and a magnifying glass to use deductive reasoning. These methods come in handy every day! If you lose a toy, for example (or car keys), you may make your search easier by determining where the item isn’t.
“Oh yeah,” you may say, “I didn’t bring it to my friend’s house; I wasn’t holding it when I walked to the living room, or landed on the moon. I wouldn’t have brought it to my parents’ room or under the ocean or into Mordor.” By deciding where you shouldn’t look, you now have a better idea of where you should.
This kind of logic process happens throughout the day, sometimes without you even being aware of it; you might say your brain is always on the case as much as any detective!
Apply deductive reasoning the next time you’re in the bookstore: subtract the books that don’t meet the highest educational standards, offer pages of activities and facts, offer online supplements, are fun to look at and fun to read! You’ll be left with books by Sylvan Dell like The Deductive Detective!
