I was lucky enough to find different colored zippered pouches at Wal-Mart. This is a little more costly but definitely beats all those baggies. For my themed activities, I store them in small laminated manila envelopes with labels. (I have been including labels with directions in my newest TPT units- to assist with organizing and labeling the activities)
Small bin labels for literacy and math center activitiesI love to stay organized and label my materials and manipulatives. It makes it so appealing to the eye and "easy" to find everything. Below are my math and literacy manipulative labels. I have slowly been ready Debbie Diller's Math Work Stations book and have to say I wish I had ordered it sooner.

I hope these labels help you as much as they have helped me to stay organized all throughout the year.
