Why are there no Enotes for 'The Owl in the Shower' and 'Pirates of the Caribbean Jack Sparrow Silver'  These are text for 5th grade?

The simple answer to this is that guides on these texts have not been requested and/or written. The e-notes editors respond to demand: we answer questions posed and produce assignments and teaching guides on texts requested by e-notes users. The request can come from students or education professionals. If you require specific detail, I suggest you ask a specific question on a text; if you requre a teaching guide I advise that you contact Scott Locklear to add your requested text(s) to the assignment lists.

As editors we are always ready to meet demand. Ask away - I am sure that some of my esteemed colleagues will be able to help you.
