Thanks to Tasha!  This is an awesome activity that looks really cool too!  Do a search on the internet for directions to do a triorama.  Then, do it four times and glue it all together to make a pyramid of four trioramas!  Look at the pictures below to see how it was done.
One side was all about the summary.  The second side was about characters and author's purpose.  The third side was about the title and author.  The final side is about their favorite scene.
