Get or make some flash cards with site words on them-- start with the alphabet, and the sounds they make, and then small words like the, and, but, or, A, I, me, you, we, us, they, for, red, green, blue, yellow, etc.... do the flash cards with her- you say the word and make her say the word- and also writing the word will help. Any of this will help her to recognize the words.. then once she begins learning the sounds- you can read and let her do some of the souding out while she read with the finger pointing, etc..... I am a certified teacher and principal and think it is great that you are working with her and are so willing. You will not regret this decision in any form or fashion.
