This box set from DK (Dorling Kindersley) brings together six nonfiction children's books leveled for young readers at Grade 2 reading level. Designed as part of the DK Super Readers series, the collection helps children ages 7 to 9 build essential reading skills while exploring fascinating topics from the natural world, including animals and their habitats such as dogs, sloths, quokkas, giant pandas, and snakes.

Each book in the set is leveled using the MetaMetrics Lexile Framework for Reading, integrating science, geography, history, and nature topics to engage a wide range of interests. The books supplement core literacy programs and align to Common Core Standards, making them ideal for classroom or home use. Comprehension quizzes within each title reinforce vocabulary and reading retention, supporting children as they progress from beginning readers to confident independent readers.
