When you open my file cabinet, the first thing you see are file folders for September through June, separated into activities and activity sheets. For example, I have a folder labeled September-Activities, and then a folder labeled September-Activity Sheets.
This is so if I need to create a morning work activity sheet, or an after-test packet, I can quickly grab all my fun monthly activity sheets to copy. If I'm looking for a hands-on craft or game to play with the kids, I look in the activities folder. I have separated each of these monthly pages into the two sections so you can make the two folders for each month as well.
Check out Busy Teacher's Cafe Monthly Theme link for activities for this month.
