Math Code Breaker Worksheet Generator

Build a fresh crack-the-code sheet in seconds. Every letter of a secret message hides behind a math problem: your child solves it, finds the answer in the key, writes the letter, and the message appears. Choose addition, subtraction or times tables and an answer range, type your own message (a birthday wish, a clue for a treasure hunt) or take a surprise one, then print straight from your browser with or without an answer key. Tuned for Kindergarten through Grade 3.

OperationAnswer rangeSecret message (optional, up to 28 letters)Include an answer key on a second page

Every letter in the message gets its own number in the key, plus a few decoy letters, so the only way to read the message is to solve the problems. Letters and spaces only; numbers and punctuation are dropped.
