Keeping all of the pieces together really helps me from year to year. I love being able to go into my decimal or fraction bin, quickly grab the center I want and I'm done. I've also found that it works well to include all pieces when I hole punch, even the answer key and recording sheet. It makes is so easy for me to make copies of the recording sheet and then take the answer key off for quick grading. I don't have to go back to my TPT account and re-download to print the recording sheets again.
When I'm not using the centers i store them in bins that I got from the Dollar Store. I found similar ones online for $2.75 each and I feel like the ones that I have aren't that much more expensive. I would recommend getting the bigger storage bins if you are anything like me and have a center buying problem.
Each storage bin is labeled with the type of centers that are inside of them. I am currently working on organizing these bins more specifically, but as of right now it works pretty well. I would love to see how you organize your centers and if you've got any tips for me!
Happy Cyber Monday Shopping!
