Detective Themed Classroom Decor Ideas 1

A detective themed classroom is all about using observation and deduction for finding out answers. Students will value the importance of asking questions and reasoning. It really lends itself well to science and any discovery learning activities. The main colors in a detective classroom theme are yellow and black (like the caution tape).

Similar themes to a detective theme are classroom spy theme, FBI theme, Mission Impossible theme, and secret agent theme. Scroll down to see detective themed classroom decor printables.

How to Make a Secret Agent Bulletin Board: A large magnetic lined paper sheet was used at the center of this Secret Agent Handbook for Success bulletin board. The teacher added the lines ‘be honest’, ‘be attentive’, ‘be seated’, and ‘be respectful’. A yellow and white lightbulb border trim matches the yellow background.

Feature a quote: A detective theme is about persuing knowlege. So this quote ‘It is okay to not know but it is not okay to not try’ is fitting for a detective themed classroom bulletin board. Large footstep stickers were added.

  • Use locks for classroom activities: Students can unlock clues that you set out for them in classroom scavenger hunt activities. One teacher uses a three-digit password set of locks for her escape room-type simulations, like the “spy mystery treasure hunt”. She lets her students answer math problems to get the combinations and unlock more clues. The clues are kept in lockable zipper pouch bags. She knots carrying handles of the bags so that she can lock them to a padlock and keep the pouch closed, until her students have solved the clues and got the combinations.
