The Montessori child begins to read and write when he or she is ready and then proceeds at his or her own pace. A child's experiences in practical life and read-and-writing education serve as a preparation for reading and writing. For example; the sandpaper letters in read-and-writing provide a phonetic basis for reading. Also the child's desire and sensitivity to touch are utilized by these letters. He or she not only hears the sound and sees the shape, but trains his or her muscles for when he or she begins writing. Storytelling, conversation and many other exercises intrigue the child's mind therefore pursuing his interest in reading and writing words. These activities serve as preparation for when the child assimilates what he knows and explodes into writing.
