We received the Calvert Math books from a friend that was done with them and we like them, but I just realized that we're missing a few pages in chapter 4. It's an older version of the book, but I was hoping that somebody else that is using it or has it would be able to scan the pages I'm missing and e-mail them to me ? If that's not possible I'll just wing it, since i do have the practice book.... But if anybody would be able to do that, that would be great! We're missing pages 81-88(about the last half of chapter 4).
