Can you believe my high schoolers actually look forward to test days? That's because every test day I give them one of my "Brainteaser Bell Ringers" to get their brains "warmed up." In reality, it's a light way to get students' minds energized for a big test and allows the them to loosen up and smile. This Brainteaser includes 9 middle/high school level (somewhat difficult) riddles. And don't worry- an answer key is included! Enjoy!
