A Girl Called Al — Constance C. Greene

Her name is Al, not Alexandra! Al's real name is Alexandra, but she hates it. She has always considered herself a nonconformist -- she is the only girl in the entire school who wears pigtails, and when all the other girls take the cooking and sewing class, Al wants to take shop. There's just one problem: Girls aren't allowed. Al is determined only to learn useful things, like making bookshelves. With the help of her new best friend, a seventh grader who lives down the hall from her, and their building's kind superintendent, Mr. Richards, she just might get her wish.
