One of the first things that I do to prepare for the new school year is to set up my planner.
Once I’ve printed and ordered my pages, I take my planner to my local office supply store and have the front and back covers laminated for durability. 
The lamination and the spiral binding cost me less than $10.
This year, I also decided to add pockets because I previously used binder clips and paper clips to hold materials in my planner. I love these colorful binder tabs because they complement my color scheme, and I cover them with clear glossy tape for durability.
Once I have the planner assembled, I label the dates for my weekly spread, and I add in events from my school district’s calendar, my husband’s work, etc. I like to color code the events using repositionable flags because they’re easy to move when dates change. When I receive my class schedule, I will then label each block with class period and name. As the year progresses, it’s so helpful to keep track of what my students have done and what my future plans entail.
