Poor Arthur, his mom has just informed him that his teacher Mr Ratburn is going to be staying at their house for awhile. His roof was damaged in a storm and he needs a place to live, while it's getting repaired. Arthur is in a panic. He tells his parents that Mr Ratburn can't live at their house...it's just not right...school is school and home is home. But after Mr Ratburn moves in, Arthur finds out he's just a regular guy who wears jeans and tee-shirts around the house, watches TV and likes dessert. All goes well until Arthur gets an A on a very difficult math test. Now all his friends are mad at him. They won't stop teasing him and calling him names. Fortunately, Mr Ratburn comes up with a clever idea and saves the day.....Marc Brown has again written a funny, witty, gentle story about life's day to day ups and downs. His characters are very down to earth, their troubles, real and his solutions, always true to life. Youngsters easily identify with Arthur and the gang and learn simple lessons of how to handle everyday problems that pop up, time and again. You can't go wrong with an "Arthur" book. It's always a favorite and a great addition to all bookshelves.
