Math Path to 7 Billion (2017)

NGSS Standard: MS-ESS3-4


Science and Engineering Practices: Engaging in Argument from Evidence


Crosscutting Concepts: Cause and Effect; Influence of Science, Engineering, and Technology on Society and the Natural World


Year Created: 2017


Phenomena: Students engage in the mathematical phenomena of understanding how big 1 billion truly is. 


Reflection: Recently, the world's population passed 7 billion people. However, students (and people in general!) have a very difficult time actually understanding how big of a number 7 billion is. These activities are meant to address this disconnect before discussing how much of an impact 7 billion people has on our planet. I used the World of 7 Billion website to get the activities, and created a document where students can record their answers. I also worked with the math teacher to discuss common language for introducing the idea of exponential growth in the science classroom.
