Interesting timeline...However I've found that names and dates teach us little to nothing about our history. It's when you learn the personal struggles and triumfants of the names and dates that Histroy will come alive and really teach you things you thought you understood but didn't!
In this Powerpoint, students look at famous works of art and discuss how many/types of angles they see. Great introduction to angle work and motivates students to find geometry in the world! Now included is a graphic organizer to help students analyze and reflect on the art, as well as directions to create their own Angle Art Project!
