This four-week unit of study for grades 1-3 provides information and activities on 17 different dinosaurs. A 21-item pre- and post-test and a brief history of dinosaurs precede descriptions and full-page drawings of the following dinosaurs: (1) giant plant-eaters (brachiosaurus, brontosaurus, and diplodocus); (2) giant meat-eaters (allosaurus, gorgosaurus, and tyrannosaurus); (3) plated dinosaurs (stegosaurus); (4) armored dinosaurs (ankylosaurus); (5) duckbills and parrot beaks (psittacosaurus and trachodon); (6) horned dinosaurs (monoclonius, protoceratops, and triceratops); (7) lightweights (ornithomimus, oviraptor, and procompsognathus); and (8) flying reptiles (rhamphorhynchus). Following an explanation for the disappearance of dinosaurs, an activity section includes riddles, poems, a crossword puzzle, math problems, and additional activities which involve comprehension, writing, and visual perception skills. All activities have a dinosaur theme. Directions for making a dinosaur diorama conclude the activity section. A nine-item bibliography of books about dinosaurs is also included in this guide. This document is part of a collection of materials from the Iowa Education Agency 7 Teacher Center project. (EM)
