About t-rex cryptograms
Ready to be a codebreaker? Each t-rex 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 t-rex 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 t-rex 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 t-rex theme, to guess the rest. Check each finished word against the answer key.
Common questions
How does a t-rex cryptogram work?+
Each letter of the alphabet is swapped for a different letter, and the same code is used for every t-rex word on the page. You crack the code - figuring out which letter stands for which - and write the decoded t-rex words on the blank lines.
How many hints does the Medium t-rex cryptogram give?+
The Medium level gives 1 starter letter. The hints show which real letter a coded letter stands for, to get you started.
What age is the Medium t-rex cryptogram for?+
The Medium level suits ages 8-10. Cryptograms involve reading and spelling, so they work best for kids who can already read simple words; the hint count is what makes each level easier or harder.
Are these t-rex cryptograms free to print?+
Yes, completely free with no signup. Print these t-rex cryptogram puzzles as many times as you like for home or the classroom. An answer key is included on a separate page.
