It was written by Julia Cook in 2005 and I think it's a must have for every pre-school and elementary teacher out there. It's a perfectly adorable story that will open a fantastic opportunity for discussing the age old problem of interrupting. As a frequent interrupter myself it is good to be reminded.
If you'd like to do some extension lessons based on the book I've put together a few simple activity pages. They include:
Metaphor Puzzles & Recording Sheets
Vocabulary Puzzles & Pocket Chart Cards
Hyperbole Activity Page
Graphic Organizer for brainstorming strategies for behavior
