Arthur, Clean Your Room! — Marc Brown

When Arthur's mother orders him to get rid of some of the old junk cluttering his room, Arthur decides to have a garage sale.  But when his first customer, Buster, doesn't have enough money for the toy he wants, a trade is worked out. Soon word spreads that Arthur has great stuff to trade, and by the end of the day, Arthur has gotten rid of all his old junk. His mother is pleased, until she finds out that D.W. is in business too--renting out her room to store all of Arthur's new junk! Arthur, Clean Your Room! comes complete with a page of peel-off stickers to place on words throughout the book and another page of colorful garden stickers to get new readers started writing and illustrating their very own stories about Arthur and D.W.
