Geometry Jokes and Puns

Bring some humor to your classroom with this collection of the best geometry jokes and puns. These jokes are sure to add a spark of fun to your geometry lesson and give your students a good laugh (or at least a groan at your cheesy math jokes.)

As a high school math teacher, I have been collecting mathematical jokes and math puns for years to add to my math lessons. I want to make it easy for you to do the same with these funny geometry puns. 

These funny geometry jokes are school-appropriate and teacher approved. These jokes would be appropriate for any geometry class at the middle school or high school level. If you teach more than just geometry, I suggest checking out my collection of over 100 of the best math jokes or my free printable math joke of the week posters.
