Coat Check Math
Coat Check Math is Larry Smirthwaite's series of books and flashcards that help kids learn math. Larry is confident that this will be popular with kids since they love coats and love to turn them in to people and hopefully get them back. The series will include word problems like:
"Mr. Rehnquist goes into de Medici's restaurant and his party checks 16 coats, which are added to 32 coats already in the room. Two coats are lost, but two more come in, and one is lost."
Answer = 47
