The Zoology/Natural World 3-Part Reading Cards introduce children to the wondrous variety of living things and help them discover the many similarities and differences among kingdoms, phyla, classes, and species. We worked with a zoologist to make sure that each packet has the right balance of species for that group and that the set is truly representative of the diversity of the Natural World. Use the photo-only cards for vocabulary building and sorting activities. Use all 3-parts for reading activities. Begin with the great contrasts of Living and Non-living. Then, move through the kingdoms, phyla, and classes to show the finer levels of detail. For more information, download our free lesson plan describing how to use Zoology Cards along with our free zoology/natural world reference chart. Approximate card sizes are 3¾” x 4¼” (control cards), 3¾“ x 3” (photo cards), and 3¾” x 1¼” (word cards).
