The Tooth Fairy: A True Story

Last Friday I read a story with a first grade student during his independent reading time. Actually, he read to me a story of the Tooth Fairy.  His ancestors of a few generations back came from Mexico (that will matter towards the end of this commentary).

Here is our conversation after he finished reading the story:

Student: I know that the Tooth Fairy is not real.
Me: No?  (I know that this student has older siblings and I wondered what they had told him.)
Student: No.  It’s not real.
Me:  What more can you tell me?
Student: No, it’s not a fairy.  It’s a ratoncito. This is true!  In parts of Latin America it is not a fairy that leaves coins for a tooth it is a Ratoncito Pérez.
