An updated version of the Critter Finder Worksheet where Page 1 has been transformed from a static reference chart to an active, highly interactive matching and sorting worksheet just like Page 2. The activities are balanced across both pages to classify land animals (mammals, birds, reptiles, amphibians) on Page 1 and water/shelled creatures (fish, arthropods, mollusks, worms) on Page 2 using large, clear, low-text visual check-boxes and drawing lines.
