Number Coolness!

The Algebra Project teaches us , “Math Literacy is the Key to 21st Century Citizenship”.  Incorporating the most basic programming concepts is a great way to teach about different numerical systems, decoding, problem solving, and well, just how cool numbers can be. Not to mention that it is number coolness that makes technology happen. There is no better way to demonstrate all of these concepts then with the use of a simple spreadsheet, the most under utilized tool in your tech toolkit. Spreadsheets welcome everyone, Excel, Numbers, Sheets, you name it. 

Here are a few Google Sheets you may want to integrate with your curriculum that provides another way to visualize different numerical systems, their relationship to programming, and more. I am sure you will see other ways to use these. Even if all this is greek to you, try them!  You will surprise yourself with an ah ha! moment or two.
