Here is my version of Ashley over at That's So Second Grade!'s Common Core Standard Tabs for 3rd grade ELA and Math. I have created labels for K, 1st, 3rd, and 4th grade for both ELA and Math. These labels can be used to organize materials for each standard. Below you can find links to both my post and Ashley's post on how we are using the labels.
These should be printed on Avery or Office Max brand Templae 5366 File Folder Labels
