Laminate these pieces to add to your calendar. It covers each of the areas of Common Core Math. You can use it daily to spiral review the standards with your students. You can add your own numbers and information in order to work at your student's readiness levels.
I like to put magnets on the back of them and stick them to my board.
There is also a blank calendar that you can give your students to glue into their math journals. Students can turn in their calendars monthly so you can track their progress.
