Earlier this week I shared a playlist of TED-Ed lessons about how the human body works. In responses to that playlist Lisa Winer sent me the suggestion to check out a TED-Ed lesson that she contributed to creating. That lesson is the Locker Riddle. In that lesson students have to use mathematics and logical reasoning to open a locker containing an inheritance.

The Locker Riddle is one of seven TED-Ed lessons that are based on riddles. All of the lessons challenge students to logical reasoning and mathematics to solve the riddle. The playlist of riddle-based lessons is embedded below.
