Recognize the, a, I, and see instantly by sight, without sounding them out letter by letter.
Some small words do not follow the sounding-out rules very well. You already know the and a from the first story. Today you learn them for keeps, plus two new ones: I and see.
These are called heart words, because you learn to know them by heart, the way you know a friend right away. I is just one letter that stands for a whole word. See has a double e you have not learned yet, but you will read it anyway.
Mastery looks like: They recognize the, a, I, and see instantly by sight in any order, without pausing to sound them out.
Common stumbles: Trying to sound out a heart word letter by letter instead of recognizing it instantly; forgetting a heart word learned days ago without daily practice.
