K-Gr 2—Introducing symbiosis in nature, these volumes pair full-page color photos with two or three sentences of information each on facing pages. The large-type texts run to only 175—190 words per volume, and are similar but not identical to each other in wording and structure. The easy-to-understand examples are well selected to show a range of relationships in a variety of environments, and children will come away with some exposure to the concepts of "parasite" and "predator" as well.
