Content Area: Math
Domain: Measurement and Data (think of this as the heading or topic)
Cluster: Work With Time and Money (sub-topic)
Standard: Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and cent sign appropriately (think of this as all of the "files" for working with time and money)
I went through and created new folders for each topic. For example, I teach 3rd grade, so I typed a folder for every Operations and Algebraic Thinking topic (3.OA1, 3.OA2, etc...) and all other domains. That way, I can easily slip lessons that I create into those folders and they are nice and organized. Use or lose, but that's how I chose to organize it on my computer.
