Helen Keller devotes an entire chapter in her memoir—chapter 7—to learning to read.
She explains that Miss Sullivan first gave her word cards. Each card had a word on it in raised letters. Helen would connect the word to an object and then string the words together to make sentences. She would also place the correct object on or by the card with the word printed on it. For example, if she was writing a sentence with the word doll, she would place a doll by the card printed with the word doll. This helped to reinforce her learning—and she enjoyed the process.
After learning enough words, Helen began with a simple book called Reader for Beginners. At this point, she loved both reading and reading games, and all of it was more like play than work to her. If Helen liked something, such as peaches, Miss Sullivan would find a story or poem about it. The chief way Miss Sullivan helped Helen improve her reading was to make it joyful for her.
Helen particularly loved to learn outdoors, so Miss Sullivan would often take her reading lessons and books outside, which is where she also learned about science and geography.
