They Did The Monster Math Shirt | Funny Halloween Math Teacher Tee

They did the math. They did the monster math. This monster math shirt lines up nine cartoon creatures, including a mummy, a stitched-up monster, a ghost, a werewolf, a pumpkin and a little red devil, each holding pencils, calculators and flashcards like they are ready for a pop quiz.

Why Teachers Love It
