I have been trying to teach my sons his letters with no succes so far (he wants to do it). Despite being in preschool 6 hours a day, everyday and my few attempts... he just guesses or try to find the patern in my questions (ABC, ABC, ABC, so then he repeats ABC but still identify A alone, B alone and C alone). Anyhow, I tried another method today: draw a picture of something familiar (cat, cow...), ask him what it is, then I write the word down. Then I ask him to find the letters of the word and write the word with those letters made of some foam material. After he finds the letters and put them down, I go over it again and then ask him what they are (in different order). For the last word, he did not want me to help him and that little boy was trying SOOOO hard to remember. It looked more painful than giving birth (and I just had a homebirth!lol). I really did think he was focusing for real since it lasted soooo long. Anf then: he did it!! remembered the 3 letters with no mistakes!!! yeah! he can do it
