It’s a simple color coded sticker Mr. Colby Hirns places on his students at Hilliard Memorial Middle School, but it represents a portion of a continent’s population. When students see how small the U.S. is compared to the rest of the world, their eyes are opened to an understanding of what his World Studies class will mean to them. Through world history students can learn the culture and development of other nations. In this class he used stickers to grab their attention but snuck in math and team building skills too. Students created equations to determine how many people were born each day and worked together to solve the problem. Mr. Hirn’s lesson: If we just learned about U.S. history we’d never learn how the global world we live in actually works.
