I Like - Book 4 VI is the fourth out of five reading books in Series 1. Series 1 focuses on teaching students the core words I Like along with a few secondary core words from the A.P.P.L.E. literacy program. The VI (vision impairment) books are designed for students with low vision and different learning styles. All of our reading books come in two formats (photo books and illustrated/VI books) and contain identical content in order to promote inclusive teaching. Please note: the reading books are best used in conjunction with the A.P.P.L.E. Teaching Guide and Resources book.
