Have a tub/box to put your read alouds in after you finish reading them.
My classroom teacher has a tub next to her chair where she can put the books she has read that week in when she finishes reading them. I think this is a great idea because she can then quickly pick one of them up if she refers back to it while reading a different book or doing an activity about it. It is also very easy to remember what you have already read because it is all right there. Shelving the books at the end of the week is easy too because her books are organized by topic and she can simply pull of the books out and shelve them together when she finishes the week.
