I prefer to talk about the former: what should we have on hand to motivate readers? We are going to cover some familiar territory, so you returning campers can go off exploring on your own if you'd like. I have been thinking a bit about this as I see the ads for school supplies. I love supplies. I love buying new pens and paper and notebooks and such even though I no longer need to do so (almost all of my writing is done at the keyboard). But, for me, the first item on the list of supplies for motivating readers? A teacher who reads! Next? Books, right? Final supply? Time to read and talk about the books. These three things are better than any app ever will be or hope to be.
I could wax on eloquently, but I think short and to the point is the best. If you want to supply your classroom for the fall, gather up some books and start reading. We motivate kids first by showing them what is important in OUR lives.
