"Using limited vocabulary, simple sentences, and informative full-page color photographs, each book lists one amazing fact per spread. . . .Useful as browsing material and for early and reluctant readers interested in unusual facts."
School Library Journal
"This mature looking nonfiction series would be attractive to older struggling readers and English Language Learners but is also appropriate for first or second grade students. . . .The photographs are intriguing and well-chosen to illustrate the specific words in the description."
