With all the excellent non-fiction text features that we have come to expect from National Geographic, this 2016 edition, Mars the Red Planet – Rocks, Rovers, Pioneers, and More, under the National Geographic KIDS label is especially suited for the elementary school audience – Grades 4-6. When I checked with a Grade 6 teacher and several of her students, I was encouraged to hear that many of them included books as well as online resources in their inquiry projects for the Sky Science unit. ELL students and reluctant readers particularly relate to the readable text, the photographs, time lines, diagrams and illustrations that come on every page. The Table of Contents, bold headings, sub-headings and Index help students locate information. The text is concise, using a small-sized font that appeals to older readers, and it was read easily by the grade 6 students that I know. Even though they had finished their science unit, they were interested in recent, new information, and wanted to take it out of the library right away – a good endorsement!
