Packed with fun facts for kids, this innovative series of levelled guided reading books combines a highly visual approach with engaging nonfiction narratives. Reading levels progress from brief, simple text in the early readers, to slightly longer, more detailed nonfiction chapter books, to challenging nonfiction containing rich vocabulary and more complex sentence structures. Fun quizzes boost reading comprehension. DK Readers are assessed by both Fountas & Pinnell and Lexile levels, and are ideal for learning to read, for subject research, and of course, for children to read for pleasure.
