Congratulations on recognizing the signs that DD is on her way to loving reading!
My DD1 was about the same age as yours when I we did the same thing. I was introduced to Get Reading Right for parents which uses phonics. They have easy to understand material for you as a parent, and books that progress from teaching each of the 44 sounds to pre-readers and early readers. We found these much much better than others on the market, because they didn't have the obvious pictures telling the reader what each of the words were (so she needed to actually look at the sounds and blend them)! DD2 is now learning to read and when school sends home readers; many with obvious pictures, I can tell when she is guessing.
In addition, I used to take her to the supermarket and work on her vocab too. Help me find lemons, apples etc etc. Making a game out of every day activities (it also kept her busy and me from going bonkers trying to do the supermarket shopping
We also used other everyday activities to reinforce stories or play games (like sticking post-its on items around the house and having her find them. But this was done when she was about 5 and a half.
And, if you want to get tips, downloadables and free reading 'lesson' plan ideas (such as the supermarket and postit ideas). Sign up for this newsletter:http://www.phonicshero.com
Phonics Hero also has an online program which many schools use and Apps that supplement the Get Reading Right program (but you mentioned you don't have computer access).
Good luck with it!
