About mermaids cryptograms
Crack the secret code in these free printable mermaids cryptograms for kids. Every letter has been swapped for a different one, and the same code is used for all mermaids words on the page - so one starter letter is given to get you started. Decode each mermaids word and write it on the blank lines below.
Cryptograms are a sneaky-fun way to build spelling, letter recognition, and logical reasoning. Kids use pattern-spotting and process of elimination to crack the code, and the mermaids theme keeps them motivated to finish. Because the whole puzzle uses one consistent cipher, solving it rewards careful, methodical thinking - the same skill that helps with reading and math.
Start with the hint letter. Wherever that coded letter appears, write the real letter - the code is the same for every word. Use the letters you have decoded, plus the mermaids theme, to guess the rest. Check each finished word against the answer key.
