We put together this great little bundle of nine free printable secret code worksheets (seasonally themed, thank you very much), plus a “make your own” code worksheet so kids can try it themselves.

How to use secret code worksheets in the classroom

We love these worksheets as a fun activity for the whole class, but they also make a great “may do” for early finishers. Because these are seasonal secret code worksheets, you can use them throughout the year. However, we also know teachers who use them as part of a unit on mysteries or spies that includes cryptograms and ciphers.

Benefits of doing secret code worksheets

The great thing about secret code worksheets is that they’re fun and inherently motivating, but they also help students build important skills. Solving secret codes promotes problem-solving and abstract thinking skills. Reading and interpreting secret codes also supports their literacy development.
