Gallaudet's Visual Language and Visual Learning (VL2) storybooks in app form. Stories are told in ASL and English. Built on bilingual learning principles.
Couple dozen digital storybooks online in three age categories: young children, older children, and young adults. Texts and illustrations. No built-in read-aloud option, but can't beat the price.
Read aloud on the "Between the Lions" tv show. Animation, effective read-aloud, text highlighted by phrase to assist beginning readers in following along. Nicely done.
