The document discusses several approaches to teaching reading:
1. The global reading approach assumes reading is best learned through natural text and focuses on memorization of whole words.
2. Examples given are language experience activities, neurological impress activities using books/charts, and shared reading of stories.
3. The phonics approach teaches reading through learning sound-letter correspondences and applying this to build word recognition.
4. Sight words are words that cannot be sounded out and must be memorized through repetition and context.
