Engage Your Students with Independent Centers

A few months ago, I was thinking about going back to work and wondering how I am going to manage doing so many things at once.  Right now, I am parenting, exercising, cleaning, and TpTing and feel like I can hardly handle everything.  Starting in September I will be doing all of that PLUS teaching full time!  I don't know how some of you do it, but I guess I will find out in a few months.
