About earth day cryptograms
These Medium earth day cryptograms turn a list of earth day words into a secret code kids get to break. One letter always stands for the same other letter, so cracking a few unlocks the rest. On this medium page, one starter letter is given.
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 earth day 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 earth day theme, to guess the rest. Check each finished word against the answer key.
