You may want to consider, "1001 Chess Exercises for Beginners" by Franco Masetti and Roberto Messa.
I don't know if it is exactly what you are looking for; however, if you go onto Amazon.com and search for the book, you can use the "Look Inside the Book" feature and see how the chapters are organized. This should give you a better idea if it's a book for you. Good luck.
