You know how to solve math problems. Like a detective, you sift each clue until you solve the mystery.
But what can you do when you come across a real stumper?
Well, here's one way to make sense of textbook word problems: turn them into a block puzzle. Denise Gaskins demonstrates how to use the problem-solving tool of bar model diagrams. These block-like drawings are actually a type of algebra that reveals the underlying structure of a math word problem and helps you see a path to the solution.
If you can build with Legos or play Minecraft, you can solve math puzzles.
Try your detective skills on story problems inspired by several classic books and movies, from Mr. Popper's Penguins to The Lord of the Rings. Then make up new puzzles of your own, using your favorite story worlds.
