These lecture and assessment materials were the basis of an intensive study of animal groupings. In total, there are 19 segments of notes, 19 assignments with answer keys, and an assessment. The last 8 assignments (Vertebrates) include alternate, modified versions for struggling learners. Much of the content is rather rigorous for upper elementary, but I find that students respond best to high expectations. These notes are the text portions of 16 powerpoint presentations, which are available for free as a single presentation.
