Being read to is a magical experience for kids, and is a crucial stepping stone for language learning. GLEN Books provides a collection of illustrated children’s story books in English and Spanish, narrated with synchronized text-highlight and the book pages being “turned” on the screen. The stories include popular children's classics, including adaptations of Aesop's fables and Indian folk tales, as well as original stories. Kids don’t need to know how to read in order to enjoy these beautifully illustrated stories by our expert narrators, but the audio-synced text highlighting provides a constant invitation to step into reading. Beginning readers can practice and develop their skills by turning off the narration, or by playing audio for selected phrases in the text. GLEN Books can be used to strengthen language skills for children at homes or in informal preschool environments, as well as a complement to in-class activities in Kindergarten-1st grade school settings. The auto-narration feature allows parents and caregivers to enjoy story-time with their kids regardless of their own level of literacy. Skilled teachers can craft a rich set of reading, comprehension and bilingual activities around GLEN Books. KEY FEATURES * Children’s stories in English and Spanish * Designed to engage kids of all ages with rich illustrations and warm narration * Audio-synced text highlighting is an invitation to reading * Flexible auto-narration: on, off, and phrase-by-phrase * Adapted children’s classics as well as original stories GLEN Books is developed by GLEN World, a nonprofit organization developing research-based learning apps to scale early English literacy.
