The All Aboard Reading series features stories that capture beginning readers' imagination while developing their vocabulary and reading comprehension. The Picture Readers, appropriate for preschoolers, combine a very simple text with rebuses. Flash cards bound in the book help make the transition from the rebus to the printed word. As the levels progress, the stories get longer, and the print size gets smaller, preparing readers for longer books with chapters. All the books are illustrated in full color, and engage a child's curiosity with a range of topics from science to sports, history, and fantasy. Grades 2 - Grade 4.
