Be sure that you have an application to open this file type before downloading and/or purchasing.
An excel file with a page for each of the content areas within the essential elements (English, Science, Math). Each sheet will have the Essential Element standard related to the Common Core with an area to add your own activities, books that correlate with the standard, and other notes that you would like to add.
You can customize your own sheet on what works best for you. You could even copy and past this list into a word document if you just want a copy of the Common Core Essential Standards of your own to manipulate.
I teach in Wisconsin so these standards are coming straight from the DPI website.
