Alphabetti books: Ages 3 - 6. These books are good for children just learning the alphabet, or as remedial education for children who struggle with letter recognition and differentiation. Beginner Phonics Books: Ages 4 - 7. These books are good for children who already know their alphabet. The books develop fluency in reading small, short-vowel words. Intermediate Phonics Books: Ages 6 - 8. These books are good for children who are comfortable reading short-vowel words. Some younger children can read these books, but proceed with caution.
Advanced Phonics Books: Ages 7 - 10. We don’t recommend these books for younger children unless they are gifted readers.
The books are also used in adult education (remedial and English as a Second Language), as well as in remedial education for middle and high school children.
The important thing is to proceed at a pace that suits the child/student. Some children/students need a LOT of repetition. Some children/students gobble it up (eat it up) and are ready to move on quickly.
