vowels

Dylan has been very tight-lipped about what he learns at school.  He will tell me about lunch, recess, music, and PE.  When I ask him about what he did in class, he will usually only tell me about centers (which his teacher says are only about 40 minutes of the day).  So, it's been a little hard to know just what he's learning since kindergartner's don't bring a lot of work home.  But the other day, I was watching wheel of fortune.  One of the contestants bought an o, and Dylan said "That's a vowel, and if you put a vowel between two consonents it makes a short sound, and if you put it between two cosonents with a vowel on the other end it makes a long sound."  I was amazed.
