Young children are simply sponges that want to learn something all the time and when they come to school especially they want to know the alphabet. Usually by the time they're 3 or 4 they've learned the alphabet song and yet that is simply a rote repetition of the letters and doesn't really teach them what the alphabet is. As they get into kindergarten teachers often times use one day for a letter of the alphabet and they immerse the children in that letter not only how to write it in the uppercase form and the lowercase form but also how does that feel. They sometimes use sandpaper and let them trace the letter with their fingers with the sandpaper or in the sand. They make them out of cookie dough. They bring all kinds of things to school that start with that letter and they use all of your senses to get going with the sense of the alphabet and what that letter means, how it sounds and where it is within words as well. But learning the alphabet for some children is very easy. For other it's quite difficult to understand what comes before what other letter because we build on all of that letter identification as we begin to alphabetize words later, learn how to use skills in the dictionary and things like that. But letters are very important. And the magical thing about the 26 letters in our alphabet is when you look at every book in the library and every book on the shelf you know that someone has taken only those 26 letters and they've made all of that writing.
