Here is a play about commitment and responsibility in love. Jack, an aspiring actor, is serious about his career but not about his girlfriend, Martha, an aspiring dancer. They drift along on a cloud of good times, until Martha gets pregnant. By the time Jack realizes he wants to make an emotional commitment to Martha and their child, she has had the baby and put it up for adoption. Martha becomes a self-sufficient contemporary woman; it is Jack who will hurt forever from the pain of eternal separation from his child.

In this book, the authors challenge some broadly-held assumptions about how children learn about fractions. After detailing their arguments, they then offer new research that could open the way for a dramatically improved way to teach children fractions.
