Award-winning “Budding Reader Book Set 4: Hop!” introduces the short “o” vowel sound and 11 new words (Bop, do, hop, hops, looks, Mop, Pop, not, they, up, will) while reviewing seven simple words previously introduced in the series (and, at, down, go, look, on, stop). Arguably the easiest learn-to-read books on the market, Budding Reader eBooks were developed in consultation with Cecilia Minden, Ph.D., the former Director of Literacy and Language at the Harvard Graduate School of Education, and Melissa Ferrell, a former Development Associate at Walt Disney Television. The series was illustrated by Doug Oglesby, winner of one Emmy, five Emmy nominations, and three international awards from the Broadcast Designers Association.
