Cryptarithms — sometimes also called alphametics — are mathematical puzzles where, instead of numbers, letters of the alphabet represent each digit. The puzzles can vary in complexity, and students must figure out the value for each letter while ensuring the equation or calculation still makes sense. This problem-solving activity is fun and engaging and really gets students to work their number-sense muscles, whether they’re solving a cryptarithm or creating one of their own. We’re sure you’ll love cryptarithms as much as we do once you give them a try.
