I have a shelf elf in my library that goes with a book about taking care of books and using a quiet voice so as not to scare the elf, who hides around the library. The Elf on the Shelf sounds great. My own kids would have loved that when they were little.
This morning in my library I called for students to clean up what they were doing and go to class. I encouraged them to have a great day and focus on something new they learned in class that they could share with me later in the day. I said to one second grade boy (who said he probably wouldn't learn anything new), "you might even learn about something like, Roman numerals!" He answered quickly and a little irritated, "Roman noodles! I can't stand the taste! Why would I want to know more about them?" I was slightly confused by his answer (I was multitasking at the time) until I figured out he was talking about ramen noodles!
