When I was a classroom teacher, one of my favorite phrases was, “no prep.” That meant an activity could be put into my lesson plan without going to a copy machine, or cutting out a bunch of stuff, or even making a quick run to a store. Prepping lesson plans is one of the many reasons teachers don’t have time to get enough sleep. Some of you are already in back-to-school mode and others will follow along later in August. No matter which category you fall into, you can use three terrific no-prep time fillers.
