Reader's Theatre is a dramatic enactment of text. Children can even write their own script from a story. Some Robert Munsch books such as "The Paper Bag Princess" and "Pigs" work well. Students read from scripts after
they have practiced pacing, expression and small actions. Usually you do not use costumes, but in some cases children could make headbands pictures attached to show what their character might look like. For example, in "The Rat Princess" I have had students attach a cloud, a rat, a sun, a wind and a rat's face to their headband to show which character they are. Students' entry and exit
on to the staging area as well as their voice projection are also important aspects of Reader's Theatre. It's easy and the kids love it. If you, as the teacher, write the script break parts up to include 3 or 4 narrators. That way you can accommodate more students.
