About planets cryptograms
Ready to be a codebreaker? Each planets word below is written in a letter-swap cipher, and one starter letter is given. Figure out which letter stands for which, then decode all the planets words. Free to print, with an answer key included.
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 planets 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 planets theme, to guess the rest. Check each finished word against the answer key.
