When my littlest kid was about this age, I remember going to a restaurant with my mom (a retired reading teacher). While we were waiting for the food, and everyone was talking about stuff, I saw my mom with a little notebook working through lists of words that she was handwriting and teaching my daughter to sound out.
She picked rhyming families and concentrated on a single internal vowel sound at a time. Then they wrote simple sentences.
By the time the food arrived, my daughter was reading sentences with no picture clues. And every now and then my mom would throw in a new word without warning that was similar and in the same family, but required my kid to look at the letters and think about what was happening.
Good teaching can take place anywhere, anytime, with the simplest of tools. You can keep your technology integrationist. I've got Grandma with a pencil.
